#4-40 × 1/2" براغي ذات رأس مقبس | رأس منخفض، محرك سداسي المقبس | فولاذ سبائكي مع أسود حراري مؤكسد (100 / عبوة)

The black oxide coating on these screws gives them a nice, even finish that makes them easy to handle with tweezers. They fit perfectly into the tapped holes on my small milling jig without any wobble.

Picked up a pack for securing a small jig on my mill, and the 1/2" length is just right for thin plates. The black oxide finish makes them look clean and should resist rust well enough for shop use.

The low head profile on these #4-40 screws is perfect for tight clearance spots in my fixture plate. The black oxide finish seems durable and the hex drive engages without any stripping. I'll definitely order another pack for future builds.
