M6-1 X 70mm براغي رأس مقبس | رأس زر محرك مقبس سداسي | كامل الخيوط | فئة 12.9 سبيكة فولاذ مطلية بالزنك (200/عبوة)

I needed a full bag of 200 for a jig build, and these 12.9 alloy steel screws feel much tougher than the grade 8.8 ones I've used before. The zinc plating looks clean and even, no flaking or rough edges on the threads.

These screws are exactly what I needed for my jig setup; the 12.9 alloy steel feels seriously tough and the hex socket drive made install a breeze. The zinc plating looks clean and uniform across all 200 pieces, which is a nice bonus for the price.

The hex socket drive fits my hex keys perfectly, which saved me time during assembly. Zinc plating looks clean and consistent across all 200 pieces, no rust worries there. Only minor thing is the heads sit a bit higher than I expected for button head.
