براغي رأس مقبس M4-0.7 × 20 مم | رأس زر محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (600 / عبوة)

I needed these for a jig I’m building, and the hex socket drive made installation a breeze—no stripping or slipping. The 12.9 alloy steel feels incredibly strong, and the zinc coating gives them a clean, durable finish. Exactly what I expected for the price.

Just finished assembling a full set of tooling jigs for a production run and these M4s held up perfectly—no stripped heads or wobble at all. The zinc plating gives them a nice, even finish that resists rust so far.

I needed a big batch of M4s for building custom jigs, and these 12.9 alloy steel screws have held up perfectly under repeated clamping pressure. The hex socket drive makes installation quick and clean with no cam-out issues.
