Uxcell Split Cotter Pin -4mm x 45mm 304 Stainless Steel 2-Prongs Silver Tone 30Pcs

Description:
A cotter pin secures two items with the use of a common hole. Place the cotter pin in the hole, the bulbous head will stop the pin from moving all the way through. Then bend the open tips to secure in place. Depending on the application, various sizes and finishes are available.

Feature:
1. Cotter pins are most frequently used to secure clevis pins or castle nuts.
2. Cotter pins insert into holes of certain types of fastener systems to secure them into place.
3. Once inserted through the hole, the two prongs at the opposite end can be separated and bent outward to lock the pin.
4. The bulbous end prevents the pin from pulled through the hole so it is important to select a pin that has a diameter measurement larger than the hole diameter in the fastener you are working with.
