براغي رأس كبس 3/4-10 × 3-1/2" | مشغل بمقبس سداسي | حبيبة نايلون | ملولبة جزئياً | سبائك فولاذ مع أكسيد أسود حراري (25 / عبوة)

I needed a 3/4-10 x 3-1/2" screw for a jig I was building, and the nylon pellet locking feature keeps these from backing out under vibration better than I expected. The hex socket drive made installation a breeze, even in a tight spot.

The black oxide finish on these screws looks and feels professional, not cheap. They’ve held up perfectly in the jig I’m building, and the hex socket drive makes them easy to torque down even in tight spots.

The partial threads on these are cut clean, so seating them in a tapped block took zero fuss. They're stiff out of the package, but the black oxide finish gives them a nice grip for wrenching.
