Charlotte D. ★★★★★

I used these on a precision jig build and the 18/8 stainless held up perfectly without any corrosion worries. The 2-1/2" length gave me just the right thread engagement for the assembly.

Jason ★★★★★

The hex socket drive grips the allen key cleanly with no wobble, and every one of the hundred screws threaded smoothly into my jig fixture. The 18/8 stainless finish looks sharp and resisted the coolant splashes during a full day of runs.

Julian P. ★★★★★

Finally an exact fit for the #5-40 thread in my fixture clamp—these are actually the right length. The hex socket drive engages perfectly without stripping.
