براغي SEMS ذات سن داخلي #4-40 × 1 بوصة | رأس بان مع محرك فيليبس | فولاد مع أكسيد أسود (800/عبوة)

Finally found some #4-40 screws that actually stay put under the driver bit; the pan head gives you a solid grip without slipping. The black oxide coating seems durable and hasn't flaked off during my assembly project. Exactly what I needed for a consistent, reliable fastening job.

The black oxide finish on these screws matches perfectly with my dark metal project parts, giving everything a clean, uniform look. The Phillips drive seated well without stripping, even when I was driving them into tight spots on the assembly. Just what I needed for a secure fastening job.

Installing these little pan head screws into tight spots was a breeze thanks to the Phillips drive, and the internal tooth lock washer held firm without any slipping.
