براغي ذات رأس أسطواني مقاس 3/8-24 × 2-1/2" | محرك سداسي | حبيبات نايلون | ملولبة جزئيًا | فولاذ سبائكي مع أكسيد أسود حراري (50/عبوة)

Used these to secure a jig on my mill table and the nylon pellet really locks them in place without needing thread locker. The 2-1/2" length was perfect for clearing the fixturing plate—no issues with stripping or fit.

I needed some partially threaded screws for a jig I’m building, and the nylon pellet is a nice touch for locking them in place. The black oxide finish looks solid and hasn’t chipped during installation.

Finally, a batch of socket cap screws that actually hold up on my jigs—the hex socket drive gives a nice, snug fit without stripping. The alloy steel finish is consistent across all 50 pieces, and I appreciated the Nylon pellet insert doing its job on the partially threaded section.
