#6-40 × 1" براغي ذات غطاء مقبس | رأس زر، محرك سداسي المقبس | ملولب بالكامل | فولاذ سبائكي معالجة حرارية بأكسيد أسود (200/عبوة)

The hex socket drives seated perfectly on my Allen key without any wobble, and the fully threaded length grabbed cleanly through my jig plate. A full box of 200 means I'll have spares for years of precision assembly work.

The black oxide coating on these #6-40 screws is holding up perfectly during assembly, and the button head gives a clean, low-profile finish on my jig setup. For the price, getting 200 pieces of alloy steel hardware this precise feels like a steal.

The hex socket drive on these #6-40 screws fits my hex key perfectly, and the black oxide finish seems durable. They worked great for securing some tooling fixtures in my shop.
