براغي كاب بمقبس 1/4-20 × 3" | محرك سداسي | رقعة نايلون | خيط جزئي | فولاذ سبيكة أكسيد أسود حراري (100 / عبوة)

Installing these on a new jig build and the black oxide finish feels durable. The hex socket drive makes them easy to tighten down securely with less effort. Solid feel for the price.

Used a handful to replace worn fasteners on a drill press table and the nylon patch let me skip the thread locker entirely, which saved time. The black oxide finish on these screws looks uniform and feels durable.

Bought a box for jig building and the partially threaded design bites perfectly without stripping. The black oxide finish seems durable so far, and the 3-inch length fit my fixtures exactly. Packed 100 per package, which is a solid value for shop work.
