Richard D. ★★★★★

The zinc plating on these thumb screws is clean and even, and the 3/8" shoulder gives just the right grip for tightening by hand without needing a tool. I've already used a dozen for quick fixture adjustments and they hold firm.

Ruby ★★★★★

Finally got around to swapping out the standard thumbscrews on my mitre gauge, and these fit perfectly with no wobble. The zinc plating gives them a nice, smooth finish that resists fingerprints. They're exactly the right size for my jig adjustments.

Victoria ★★★★★

Installed these on a jig I'm building, and the knurled shoulder gives a good grip for hand-tightening. The zinc finish looks clean and should resist rust in my shop just fine.
