Customer Reviews (5.0 / 5 · 5 reviews)

Carter ★★★★★

Just installed a set of these on my gear shaft and they held tight without stripping—the 18-8 stainless feels solid compared to cheaper alloys. Great for the price, especially with 150 in one pack.

Richard E. ★★★★★

Used a full pack securing pulleys to a motor shaft, and all 150 screws threaded in cleanly with no stripping. The 18-8 stainless steel feels durable enough for repeated adjustments under load.

Violet ★★★★★

The hex socket drive on these worked great for tightening down a pulley I was securing. All 150 screws looked uniform with clean threads, no burrs or defects.
