مسامير زنبركية M4 × 20 مم | فولاذ مقاوم للصدأ 18/8 (500/عبوة)

Exactly 500 pieces in the bag, and every M4 pin I’ve used so far slides in smoothly and holds firm. The 20mm length is perfect for lining up small brackets without any wiggle.

The 18-8 stainless steel finish gives these pins a clean, uniform look straight out of the bag, and the 20mm length seats perfectly for light alignment work. I’ve used maybe 150 of the 500 for jig fixtures, and every one slid in without binding. Solid value for the price.

Popped a couple of these spring pins into a jig alignment project I’m working on — the M4 diameter fits snugly, and the stainless finish resisted a quick spray of solvent without any rust. For light-duty fastening, they’re doing exactly what I needed without fuss. Glad I grabbed the 500 pack.
