Review on Eprosperous Aluminum Thumbscrew Gopro Color by Jarod Berthelson

These aluminum thumbscrews are fantastic value and the small screws are good in tricky situations. The only problem I noticed is that the threaded shank is 1-2 millimeters too long. The screw enters the swivel nut before the thumbscrew is tightened. If you're using an o-ring (gasket?), the screw will be the correct length, but the washer won't engage the handle tightly. Unscrewing the handle with the washer installed will damage the washer. For now, two stainless steel washers solve the problem. I can touch the thread end with a slow grinder to permanently fix the length problem. If a long medium set was offered with this short medium set, I would buy it too.
