The practical hairpin style design ensures that most bolts are tightly fitted and fixed for a long time, improve stability, prevent rotation, and will not loosen during use, helping you to complete your work efficiently.

High quality R cotter pins and hair pin will firmly hold the bolts in place, perfect used for automotive, mechanics, car garage, workshop, power equipment, cars, trucks, lawn mower and etc.

Simply insert the straight foot into the hole and press the bent foot down into the outer diameter of the shaft. After tightening the nut, insert the cotter pins into the nut groove and the hole at the end of the bolt-pull the tail of the split pin apart to prevent the nut and bolt from rotating relative to each other.
