Ball-and-Cotter Double-Locking Quick-Release Pins
These pins lock in place until you push the button to release the spring-loaded retaining balls, and can also be secured with a cotter pin for longer-term holding. Two-step locking prevents accidental removal. Use these pins in a hole as close to the diameter as possible, but not larger than the diameter at extended ball height.
Pins meet SAE AMS5643 specifications for material. They're made of 17-4 PH stainless steel for strength with some corrosion resistance, and passivated for added protection against corrosion and oxidation. They are magnetic.
