Same as the kanka at 17 inch pounds or 9 Inch pounds more than the right tool We'll skip the heavy duty welding since It doesn't have a swivel head so the Right tool has the most efficient swivel Head at only eight inch pounds Irwin Performed well at 11 7-inch pounds into Crescent and Stanley Proto 12 inch Pounds when I Can't Get Enough clamping Force with just using hand force on the Handle a cheetah bar really helps so Let's see how much force we can achieve Before bending the handles and the shop Tech made it to 812 pounds before the Handle became bent and the Pittsburgh Claims to be industrial grade clamp and A Pittsburgh briefly made it to 2163 Pounds before losing ground the frame of The Pittsburgh now has a small Bend and A wind is out performing the Pittsburgh Throughout the Showdown and it Outperformed the Pittsburgh and this Test tube making it to 2568 pounds the Wind's frame did experience a small Bend At 14 the Irwin is priced for Value Andy Irwin outperformed the win by almost 750 Pounds finally reaching a peak force of 3 321 pounds with the handlebent the Irwin's frame and adjusting screw are Still in good shape the heart and cost The same amount as the Irwin but Delivers half the performance at 1 537 Pounds the handle is badly bent just Like the hardened the pony struggled in
This test with the frame beginning the Bend at 1 562 pounds and a Performance Tool ran out of performance at 1416 Pounds and it didn't go down quietly the Handle is now bent and the Lincoln Electric performed about the same as the Pony at 1 681 pounds when the frame Began to twist and a yoast is pretty Heavy duty at just over five pounds and It performed by far the best yet at over 5 300 pounds the handle is the first to Go but the frame is Not Bent for a Lightweight clamp that only weighs three Pounds the grows perform well making it To 3 669 pounds when the frame began to Twist the bestie is also pretty Lightweight at 2.79 pounds and it also Performed well at 3 625 pounds when the Frame began to bend and the kanka weighs Just a little bit more than the Irwin But it's quite a bit stronger at 4 354 Pounds which is good enough to move into Second place behind the yoast the frame Has a small Bend and a Bessie F style Clamp is rated for 1 330 pounds and it Did better than advertise at 1 615. the Frame does have a very small Bend and The Crescent moves into the lead at just Over 5 700 pounds unfortunately the Threads are now galled and the clamp is Very difficult to work with and the Stanley Proto weighs just over five Pounds and it performed by far the best Yet at almost nine thousand pounds just
Like the crescent the threads are now Galled and it's very difficult all to Work with and the right tool is just Under five pounds but it outperformed All the other brands at just over nine Thousand pounds when the frame began to Twist and the adjusting screw was still In great shape and the frame is Not Bent And the Wilton is the heaviest clamp yet At 5.59 pounds but the weight Advantage Isn't enough almost 6 400 pounds is About 3 600 pounds less than the right Tool and the Wilton's adjusting screw is Now bent and the heavy duty Wilton is Designed for bridge and shipbuilding and It delivered more than three times as Much force as the second place finisher At almost 34 000 pounds very impressive No damage to the Wilton so the heavy Duty Wilton came out on top at 33 880 Pounds right tool finished in second at 9060 and Stanley Proto 8 980 pounds if a Clamp is already under load let's see How much holding Force each brand can Offer before experiencing damage and the Shot Tech went in two different Directions at 980 pounds and the Pittsburgh performed better than the Shop Tech making it to 2581 pounds when The frame broke and the cast metal is Pretty brutal and the wind outperformed To Pittsburgh on previous tests and the Win outperformed the Pittsburgh on this Test too finally breaking into almost
4000 pounds at 3 500 pounds the frame Began to bend and twist and the Irwin is Finished at just under 3 900 pounds the Adjusting screw just isn't very refined On the Harden but the frame offers Pretty good strength at over 5200 pounds The frame is badly bent but it didn't Crack and the pony weighs a little bit Less than the Harden and it also gave up A little sooner when the frame snapped At 2765 pounds the Performance Tools Adjustment screw doesn't offer too much Clamp load but the frame does have Pretty good strength at almost 4 200 Pounds the frame in the adjustment screw Are badly bent and the Lincoln Electric Frame made it to almost 3 200 pounds When things went from happy to Snappy And the Lincoln Electric is finished and The yoast refused to break making it to Almost ten thousand pounds instead of Bending and holding the bend the frame Returned to the original position once The tension was removed and it grows as Two pounds lighter than the yoast and it Grows made it to just over four thousand Pounds when it suddenly snapped I made a Couple attempts to reach failure point With the Bessie and it made it to almost 5 000 pounds when the frame experienced A really bad Bend I also made a couple Attempts to reach failure point with the Kanka and it made it to almost six
Thousand pounds the frame is now Twisted In bed and the Bessie style F clamp is Very light and quick to use it made it To just over 2 000 pounds when the frame Began to twist and bend and the Crescent Is made of drop forward steel and it's Extremely durable finally giving up at Just over ten thousand pounds the frame Did experience a bend the drop forward Steel frame on the Stanley Proto is even Stronger than the crescents finally Giving up at over 11 000 pounds the Frame did experience a pretty bad Bend And the right tool is outperformed the Previous Brands throughout the Showdown And is back in the lead again at just Over 11 300 pounds the frame did Experience a small Bend and the Wilton Made it to just over 9 200 pounds and That's all the frame can handle after a Couple of attempts the frame and Adjusting screw are now bent and the Wilton C-clamp is rated for 27 500 Pounds and the hydraulic ram is way over Its 20 ton rating and the Wilton is Stretching but not bending or breaking And 50 327 pounds very impressive no Damage to the Wilton so the heavy duty Wilton came in on top at over 50 000 Pounds right tools and Stanley Proto Both finished at over 11 000 pounds and Crescent at just over ten thousand for Many applications throw capacity can Make a huge difference and the best EF
Clamp has the most capacity at 4.6 Inches the Yost and wiltner at four and A quarter inches Crescent Proto and Right tools 4.2 inches so with C-clamp Is the best if it's all about Brute Force the heavy duty Wilton is in a League of its own in my opinion it's way Too large heavy and expensive for most Applications the Stanley Proto and right Tool both performed extremely well but Both of them fall within the buy ones And cry one's category when it comes to Price and it's all about affordability I Really like the Irwin at only 14 it Performed extremely well I definitely Don't say it enough I just want to thank Everyone that supports the channel Through YouTube memberships as well as Patreon for helping me fund the Destruction I have a lot of fun testing Products and it really helps to know the Failure point of each tool all the Videos in this channel including this One our viewers suggested so if you have A video idea I hope you'll take time to Leave a comment thanks so much for Watching please take care and look Forward to next time
