#10-24 × 3/8" براغي ذات رأس أسطواني | محرك سداسي | صنع في الولايات المتحدة | سبيكة فولاذ معالجة حرارياً بأكسيد أسود (400 / عبوة)

The hex socket drive on these screws grips my Allen wrench perfectly, making assembly on a small fixture effortless. The consistent threading across all 400 pieces is reassuring for a precision job. They feel solid and well-made.

The black oxide finish on these is perfectly uniform across all 400 pieces, and the hex sockets are cut deep enough that my Allen key grips without any slipping. Threads ran clean through my steel fixture plates without a single binding issue. Exactly what I needed for precision tooling work.

Installed these in a jig I'm building and the black oxide finish looks clean and professional. The hex drive sockets are crisp, no stripped heads even with a cheap Allen key. One fewer thing to worry about on a tight job.
