براغي رأس أسطوانية سداسية 5/8-11 X 1-3/4" | رأس مسطح محرك سداسي | سنون كاملة | نحاس (25/عبوة)

I needed brass fasteners for a marine project, and these fully threaded flat head screws seated perfectly flush with my workpiece. The hex socket drive held up well under torque without stripping.

These brass screws cut clean threads into my steel fixture without any galling, and the hex socket drive made them easy to torque down precisely. The fully threaded shaft gave me exactly the grip length I needed for a tight assembly.

Installing them in a jig, I was pleasantly surprised how smoothly the hex drive seated without stripping. The brass finish gives them a clean look, and the 5/8-11 threading matched up perfectly with my existing setup.
