3/8in clamp load (5 sec, low torque)
- 1Snap-on 3/8in and 1/2in universal joint11,955 lb3rd
3rd place in the 3/8in clamp-load ranking
- 2Stanley Proto 3/8in and 1/2in universal joint9,692 lb
- 3Showmemy 3/8in and 1/2in universal joint12,630 lb1st
the best clamp load of any 3/8in brand tested
- 4GearWrench 3/8in and 1/2in universal joint
'less than 100 lb behind the Showman [Showmemy]' - per the closing recap this is 12,534 lb, 2nd place in the 3/8in clamp-load ranking
- 5Workpro 3/8in and 1/2in universal joint
a clamp-load figure of 11,397 lb appears in the transcript attributed mid-sentence to 'the Duratech' moving into second place, but the surrounding sentences ('the Workpro is making torque quickly just like the Duratech... just like the Workpro, the Duratech is hitting really hard... at only 10.6 degrees of slop, the Workpro held up really well') strongly suggest this figure actually belongs to Workpro, with Duratech's own clamp load already separately stated as 11,386 lb; treated here as Workpro's true 3/8in figure per the brand-testing-order gotcha, but the transcript's own mid-sentence brand swap is preserved as a flag
- 6Icon 2-piece 1/4in-drive-less universal joint set9,520 lb
- 7Duratech 3/8in and 1/2in universal joint11,386 lb
(see Workpro's entry for a separate, possibly mislabeled 11,397 lb figure attributed to 'the Duratech' moments later in the transcript)
- 8Craftsman chrome, impact-rated, full lifetime warranty ($50 SKU)9,878 lb
- 9Neiko10,384 lb
described as 'performed better than average'
- 10Libraton10,992 lb
('around 400 lb less than the Workpro')
- 11Capri Tools9,891 lb
described as struggling to make torque
- 12Lexivon8,681 lb
the weakest 3/8in clamp-load result of any brand explicitly given a number
- 13Sunex Tools9,808 lb
('about 2,700 lb less than the GearWrench')
- 14Craftsman 3-piece set, not impact-rated ($17 SKU)9,204 lb
- 15Casoman9,256 lb
described as having 'way too much impact energy dissipation'
- 16Wett9,057 lb
('almost 1,000 lb behind the EPAuto'), despite having the best (least) starting slop of the video at that point
- 17Pittsburgh Pro, 3/8in and 1/2in universal joint8,772 lb
('about 1,300 lb less than the EPAuto'); described as suffering the 'Harbor Freight death wobble' after about half a second
- 18EPAuto 3/8in and 1/2in universal joint10,009 lb
less than half the torque the Milwaukee wrench delivered through a socket alone (20,407 lb baseline)
3/8in slop
- 1Snap-on 3/8in and 1/2in universal joint
started 7.6 degrees, ended 9.8 degrees - 2nd best (least) slop of the 3/8in test
- 2Stanley Proto 3/8in and 1/2in universal joint
started 8.2 degrees, ended 12.5 degrees - but per the closing recap, Proto has the least slop overall (8.7 degrees is credited to Duratech instead; see that entry for a transcript inconsistency note)
- 3Showmemy 3/8in and 1/2in universal joint
started 9.4 degrees, ended 10.2 degrees - 3rd best (least) slop of the 3/8in test
- 4GearWrench 3/8in and 1/2in universal joint
started 8.9 degrees, ended 12.2 degrees
- 5Workpro 3/8in and 1/2in universal joint

- 6Icon 2-piece 1/4in-drive-less universal joint set
started 12.1 degrees, ended 14.5 degrees
- 7Duratech 3/8in and 1/2in universal joint
started 7.5 degrees (best yet at the time), ended 8.7 degrees - per the closing recap this 8.7-degree figure is the least slop of any 3/8in brand in the whole video, though the recap sentence itself names the brand 'Duralast' rather than 'Duratech'
- 8Craftsman chrome, impact-rated, full lifetime warranty ($50 SKU)
started 20.5 degrees (a tremendous amount), ended 23.1 degrees
- 9Neiko
started 13.5 degrees, ended 17.7 degrees
- 10Libraton

- 11Capri Tools

- 13Sunex Tools
started 9.8 degrees, ended 12.5 degrees
- 14Craftsman 3-piece set, not impact-rated ($17 SKU)
started 19.6 degrees, ended less than 2 degrees higher (per narrator, 'held up better than the EPAuto and the Pittsburgh with less than 2 degrees of additional slop')
- 15Casoman
started 11.6 degrees, ended 15.5 degrees (almost 4 degrees of extra slop)
- 16Wett
started 8.1 degrees (the best yet at that point in testing), ended 11.2 degrees
- 17Pittsburgh Pro, 3/8in and 1/2in universal joint
started 28.1 degrees (same as EPAuto), ended 39.9 degrees - the largest slop increase of the standard clamp-load test
- 18EPAuto 3/8in and 1/2in universal joint
started 28.1 degrees (worst starting slop, tied with Pittsburgh), ended 30.3 degrees; one of the pins was noted as about to fall out during testing
1/2in slop
- 1Snap-on 3/8in and 1/2in universal joint
started 2.6 degrees, 3.7 degrees after the first stage, 4.3 degrees final (only 1.7 degrees of additional play) - 2nd most durable of the video
- 2Stanley Proto 3/8in and 1/2in universal joint
started 2.6 degrees (same starting point as Snap-on), 2.9 degrees after the first stage, 3.9 degrees final (only 1.3 degrees of additional play) - the single most durable universal joint in the entire video
- 3Showmemy 3/8in and 1/2in universal joint
started 5.7 degrees, 7.8 degrees after the first stage, 11.3 degrees final
- 4GearWrench 3/8in and 1/2in universal joint

- 6Icon 2-piece 1/4in-drive-less universal joint set
started 4.3 degrees, 5.1 degrees after the first stage, 7.3 degrees final
- 7Duratech 3/8in and 1/2in universal joint
started 4.9 degrees, 7.1 degrees after the first stage, roughly 11.1 degrees final (the transcript states '10 second rodeo caused 4 degrees of additional play' but does not explicitly restate the resulting total; 11.1 is derived by adding that 4 degrees to the 7.1-degree reading)
- 9Neiko
started 4.4 degrees, 6.2 degrees after the first stage, 11.5 degrees final
- 10Libraton
started 6.9 degrees, 8.3 degrees after the first stage, 12.9 degrees final
- 11Capri Tools
started 4.1 degrees, 5.6 degrees after the first stage, 6.8 degrees final - held up better than most
- 12Lexivon
started 6.3 degrees, 8.2 degrees after the first stage, 11.7 degrees final
- 13Sunex Tools
started 6.3 degrees, ended 11.4 degrees after the full 10-second test (no intermediate reading given)
- 17Pittsburgh Pro, 3/8in and 1/2in universal joint
started 15.3 degrees, 18.4 degrees after the first pass, 23 degrees after the full 10-second abuse test ('did stay together, but it is a handful to manage')

- 4GearWrench 3/8in and 1/2in universal joint3,420 g
stated in the transcript as 'just under 6 pounds' though 3,420 g actually converts to about 7.5 lb; the gram figure is preserved as spoken and the pound conversion is flagged as inconsistent rather than corrected
- 5Workpro 3/8in and 1/2in universal joint
confirmed true figure is 'over 6 kilograms or around 13 pounds,' by far the best result at the time it was tested, finishing 3rd overall in the closing recap at 13.29 lb; a separate, much lower figure ('really struggled in this test at only 1,396 grams or about 3 pounds') is also attributed to Workpro later in the same test segment but directly contradicts this confirmed 13.29 lb closing-recap figure, so the 1,396 g reading is flagged as an unresolved brand mislabel rather than assigned to Workpro
- 7Duratech 3/8in and 1/2in universal joint
a figure of 3,236 g ('moves into third place behind the Pittsburgh') is given under the name 'Duralast'
- 9Neiko3,582 g
'about the same as a Craftsman' (unclear which Craftsman SKU is meant)
- 10Libraton
'just under 2 kilograms or just over 4 pounds,' described as struggling
- 11Capri Tools

- 8Craftsman chrome, impact-rated, full lifetime warranty ($50 SKU)
tentatively 16,958 lb, from a data thread that says 'just like the 3/8 Craftsman universal joint, the half-inch Craftsman is pretty loose at 14.9 degrees... performed better than average at 16,958 pounds... now at 15.6 degrees... the most of all the single joint adapters at 17.1 degrees'; assigned to this (impact-rated, presumably single-jointed) SKU rather than the non-impact-rated 3-piece SKU, but see notes for an unresolved third Craftsman data thread in this same test
- 9Neiko15,253 lb

test had to be stopped early because both pins vibrated loose and the joint was 'about to fly apart'; pins were pushed back into position and slop went from about 17 to 19.8 degrees (this starting figure does not precisely match the 16.0-degree derived total from the prior pass, preserved as spoken rather than reconciled)

How it was tested
- weight, range of motion (degrees of articulation), and baseline slop measurement for each 3/8in universal joint
- 3/8in clamp load after 5 seconds of impact-wrench torque at a fixed lower setting, then post-test slop remeasurement
- 3/8in detent-ball/pin retention test (force in grams/pounds required to release a socket)
- 1/2in universal joints: baseline slop, then clamp load and post-test slop after 5 seconds of impact torque at a lower setting
- 1/2in universal joints: a 10-second high-torque 'abuse' test (5 sec tightening + 5 sec loosening at the impact wrench's highest setting), with clamp load and slop measured before, mid-test, and after
- microscope inspection of wear on the pin/socket contact points for select brands
- physical profile/diameter comparison to assess fit in tight spaces, separated by double-jointed vs single-jointed design
“The Snap-on had by far the best average finish of 2.3. It's definitely the best universal joint in the lineup, but it is extremely expensive.”
Data notes and caveats
17-brand (18-SKU, since Craftsman has two distinct products) universal-joint showdown across two socket sizes (3/8in and 1/2in), matching the channel's largest-showdown format; a Milwaukee impact wrench delivering 20,407 lb (3/8in, socket only) and 21,300 lb (1/2in, socket only) serves as the reference ceiling throughout and is not itself a competing product. The video's final verdict uses a computed 'average finish' ranking across all sub-tests rather than a single test: Snap-on wins overall (2.3), Stanley Proto is runner-up (4.3), and Showmemy is explicitly named the value/budget pick (5.7, at $17, 'outperformed a lot more expensive brands'). This is one of the more caption-garbled videos processed: the brand introduced as 'Duratech' is called 'Duralast' in every later mention (resolved as the same product via matching numbers); 'Showman' drifts to 'Show Me Me'/'Show Me Minnie' for 'Showmemy'; 'Wet' resolves to 'Wett'; the description's 'Libration' conflicts with the transcript's consistent 'Libraton' (flagged, not resolved). The half-inch abuse-test section has an unresolved data-attribution problem: a clamp-load/slop sequence attributed to 'Craftsman' (10.2 to 15.2 degrees, 13,711 lb) doesn't cleanly map to either of the two actual Craftsman SKUs purchased, and a low detent-test figure (1,396 g) attributed to Workpro directly contradicts Workpro's own confirmed closing-recap detent result (13.29 lb); both are flagged as unresolved caption/brand-mislabel ambiguities rather than force-assigned. Casoman and Wett were only tested at the 3/8in size; no 1/2in data exists for either in this video.
