براغي رأس أسطوانية 1/4-20 × 7/8" | محرك سداسي | صناعة أمريكية | فولاذ سبائكي مؤكسد حراري أسود (200/عبوة)

I needed a good batch for my jig and these socket cap screws went in clean without any stripping. The hex drive engages the driver tightly, and the 200 count will last me through several projects.

The hex socket drive bites well with a standard Allen key, and the 7/8" length fit my jig setup perfectly. Finish is consistent across all 200 pieces—only wish the threads came slightly pre-oiled for smoother first seating.

The black oxide finish on these screws is holding up well against my oily shop environment, and the hex drive seated perfectly without stripping. Took a star off only because the package arrived with a few rattling loose inside the bag, but the threaded holes all cleaned up fine.
