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

Used a few of these to pin a bush hog linkage arm and they held tight even with the vibration. The 5/16" diameter was a perfect fit in the pre-drilled holes, and the slotted design made installation straightforward.

Putting these in to hold a mower deck spindle was a breeze. The slotted end makes installation quick with just a screwdriver, and the steel feels sturdy enough to handle the vibration. Exactly what I needed for heavy equipment pins.

I needed a bulk pack for my tractor's PTO shaft and these spring pins worked perfectly—the steel is sturdy enough to handle heavy vibration without bending. 500 was way more than I'll use at once, but the price per piece makes it worth storing the extras.
