براغي رأس مقبس M12-1.75 X 55mm | رأس مسطح بمحرك مقبس سداسي | خيط كامل | فئة 12.9 فولاذ سبائكي مطلي بالزنك (50 / عبوة)

The zinc plating looks clean and even across all 50 pieces, no flaking or rough edges right out of the bag. Threads cut smoothly into my jig base without binding, and the hex socket seated perfectly every time. For the price per unit, these are solid for precision assemblies.

I needed a set of high-strength bolts for a press jig, and these 12.9 grade ones fit perfectly without any wobble. The hex socket drive made torquing them down easy even in tight spots.

These M12 screws were perfect for clamping down a router lift on my workbench. The hex drive seated smoothly without stripping, and the zinc plating looks clean. They hold firm with zero flex.
