براغي رأس مقبس #5-40 × 2-1/2 بوصة | محرك مقبس سداسي | فولاذ مقاوم للصدأ 18/8 (100 / عبوة)

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.

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.

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.
