مسامير زنبركية 7/16 بوصة × 3-1/2 بوصة | مشقوقة | فولاذ مطلي بالزنك (300 / عبوة)

Zinc plating looks clean and even across all 300 pins, and they slid into the alignment holes with just the right amount of resistance. Used them to secure a hydraulic cylinder mount on a skid loader, and they’ve held tight through a week of heavy use.

Installed these to hold a tractor's PTO shaft in place, and the 3-1/2" length was just right for the frame thickness. They slid into the slotted holes cleanly and the shear load hasn't budged them a bit.

These pins slid right into place without any binding, and the zinc plating is even and clean across all 300 pieces. I've been using them to hold a jig together under constant vibration, and they haven't budged a bit.
