  • EXTENDED PRONG DESIGN: One prong of the cotter pin is extended for easy insertion into a punched or drilled hole
  • BULB HEAD: Stops pin from moving all the way through a punched or drilled hole when inserted
  • EASY INSTALLATION: Parts install easily using either standard or needle-nose pliers
  • CORROSION-RESISTANT: Zinc plating and rubber material offer strong protection against rust and corrosion

It is a pin.

2 years ago
It is a cotter pin. If you bought the right size, it does its job. Can say with certainty, but the odds are that I'll lose it before it wears out.

Yes, I recommend this product.
