M4-0.7 X 14mm براغي ذات رأس مقبس سداسي | رأس مسطح محرك مقبس سداسي | خيط كامل | فولاذ سبائكي فئة 10.9 مطلي بالزنك (600 / عبوة)

For the price per piece, you can't beat the Class 10.9 alloy steel on these – they've held up great in my jigs without any stripping. The zinc plating is consistent across all 600, and the flat heads sit flush just like I need them to.

Used a full pack building a custom jig for my drill press and every single screw seated perfectly without stripping. The zinc plating is smooth and even, making them easy to handle with magnetic bits.

Bought these for a fixture plate and the hex socket drive seated perfectly every time. The 10.9 alloy steel feels solid, and the zinc plating's held up after a week of clamping and adjusting. For 600 pieces, the price per screw is hard to beat.
