Also known as double-acting pins, these pins lock in place until you push or pull the handle to release the spring-loaded retaining balls. Use them in a hole as close to the diameter as possible, but not larger than the diameter at extended ball height. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

Pins meet NAS1332 specifications. 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.
