M12 X 35mm براغي رأس سداسية بنقطة كوب | فولاذ سبائكي مطلي بالزنك (100 / Pkg.)

The cup point bit into the steel shaft cleanly on the first try, and the zinc finish kept them rust-free after a week in a damp garage. Torqued them down with a hex key in a cramped corner where a wrench never would've fit, and all 100 held firm.

These set screws held up perfectly under heavy clamping load without any stripping or deformation. The zinc plating looks clean and even, and the cup point bit in firmly even on slightly uneven surfaces.

The hex drive lets me torque these down precisely even in awkward spots on my rig. These cup point screws grab and hold tight without camming out. A solid 100-pack that handled my whole project with plenty left over.
