براغي إبهام كتف 1/4-20 × 3/8" | فولاذ مطلي بالزنك (50 / عبوة)

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.

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.

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.
