براغي SEMS مسننة داخلية M6×8mm | رأس مقبس فيليبس | فولاذ مطلي بالزنك (100 قطعة/عبوة)

Picked these up for some dashboard bracket assembly and the internal tooth lock washer really holds tight without marring the plastic surface. The zinc plating feels smooth and corrosion-resistant right out of the bag, and the Phillips drive bit seated cleanly for a solid grip.

The Phillips drive sunk in perfectly with my drill bit, and the zinc plating looks uniform across all 100 screws. These M6s held a bracket to a steel beam without stripping.

The internal tooth lock washers grip the metal surface really well, which keeps these screws from vibrating loose. Used them to secure a small bracket on my workbench and they held tight without any stripping. Great value for a hundred-pack.
