براغي رأس مقبس M5-0.8 X 16mm | رأس زر بمحرك سداسي | خيط كامل | سبيكة فولاذ درجة 12.9 مطلي بالزنك (400/عبوة)

The hex drive seats the Allen key perfectly, no stripping even after tightening a dozen into my drill jig. Zinc plating looks clean and the 12.9 grade feels plenty tough for the fixture work I’m doing.

I’ve been using these M5-0.8 x 16mm screws for mounting brackets on a metalworking fixture, and the hex socket drive makes them easy to tighten precisely. The zinc plating has held up well in my shop without any rust after several weeks.

My jig build needed a solid batch of fasteners and these 12.9 alloy steel screws came through without a single stripped head. The zinc plating has a clean, uniform look and they threaded into my tapped holes with satisfying precision. For 400 pieces, this is a buy-once-and-done deal.
