براغي رأس أسطواني M5-0.8 × 20 مم | محرك سداسي داخلي | ملولبة بالكامل | فئة 8.8 من سبائك الصلب مطلي بالزنك (400 / عبوة)

The hex socket drive grabbed my Allen key cleanly every time, no stripping even after I torqued them into a steel jig. The zinc plating held up fine against the coolant splashes in my shop. Just the right length for clamping 15mm plates without bottoming out.

These M5 screws were exactly what I needed for a jig I was building, and the zinc plating on all 400 pieces looks evenly done. The hex socket drive held up well under a fair amount of torque without stripping.

The hex socket drive on these M5-0.8 x 20mm screws made assembly much easier than using a standard Allen key. I used a full pack for a small jig build, and the zinc coating held up well without any rust. Exactly what I needed for precision work.
