مسامير زنبركية 5/16" × 3/4" | مشقوقة | فولاذ (500 / عبوة)

Been using these in a farm equipment repair and they hold up great under constant vibration. The 5/16" diameter fits perfectly into existing holes.

I needed a batch of these for a tractor attachment rebuild, and the slotted design made installation quick with just a flathead screwdriver. The steel feels solid, and they held up fine under the vibration so far.

Ordered these for a jig I’m building, and the 5/16" diameter is spot-on for the bore I drilled—no binding, no slop. The steel finish has a nice, uniform sheen out of the bag. Only gripe is the packaging: a few pins had light surface scuffs, but nothing that affects function.
