1/2-20 × 2-1/4" براغي رأس كب | رأس زر سداسي | ملولبة كاملة | سبيكة فولاذ حراري أسود مؤكسد (50/عبوة)

The black oxide finish on these screws is just what I needed for a tooling fixture where corrosion resistance matters. They threaded in cleanly and the hex socket held the driver without any slipping.

Had to swap out a worn bolt on a jig at the shop and these fit perfectly, the hex drive grabs cleanly and the black oxide looks proper. They're fully threaded which made positioning easy, and at fifty per pack I've got spares for the next project.

The black oxide finish on these screws is exactly what I needed for my tooling setup—no glare, and they thread smoothly into the alloy steel parts. They're fully threaded, so I can use them for clamping without worrying about length. Pack of 50 means I've got spares for the next project.
