مسامير زنبركية 5/16 × 2-1/2 بوصة | مشقوقة | فولاذ (500 / عبوة)

Used a dozen of these to secure some heavy-duty shelving brackets in my workshop, and they drove in clean with no bending. The slotted design really held tight under the vibration from my table saw. Solid buy for the price.

I was a bit skeptical about buying a bulk pack of pins, but these are perfect for my tractor's mower deck. The steel feels sturdy and the 2-1/2 inch length holds everything tight even with the constant vibration.

The slotted design made alignment so much easier during assembly, and the steel finish handled heavy vibration without any issue. These pins are holding together a new bracket on my tractor with zero movement so far.
