براغي ذات رأس مقبس #10-32 × 1 بوصة | محرك سداسي | حبيبات نايلون | ملولبة بالكامل | فولاذ سبائكي مع أكسيد أسود حراري (100/عبوة)

Used a handful to secure a jig fixture on my milling table, and the nylon pellet let me lock them in place without any loosening under vibration. The hex socket drive made installation straightforward with a standard Allen key, and the black oxide seems durable. Pack of 100 should last me through se

The black oxide finish on these screws gives them a nice, uniform look, and the hex socket drive made installation into my precision assembly much easier than with Phillips heads. I've already ordered another pack for a second jig.

Installed these in a jig I’m building and the hex socket drive made setting them deep into a counterbore so much easier. The threads cut cleanly into the tapped holes without any binding.
