براغي مقبس نقطة مسطحة M5 × 4 مم | سبيكة فولاذية (1000 / عبوة)

Used these for a few small machine adjustments where a hex key was the only tool that fit—worked perfectly. The flat point holds well once tightened, and 1000 per pack means I won't run out anytime soon.

Finally found M5 x 4mm set screws that actually fit the tiny hex driver without stripping, and the flat point holds tight on my indexing jig. The alloy steel feels solid, and a full thousand pack means I won't run out mid-project.

Just used a full pack on a jig I'm building and the hex socket drive made tightening them up in recessed holes a breeze. The alloy steel feels plenty tough for the clamping force I need.
