Knob-Grip Super-Corrosion-Resistant Locking Quick-Release Pins
Also known as R-style marine pins, these all-stainless steel pins stand up to corrosive environments and are passivated for added protection against corrosion and oxidation. The extra height and smaller width of the grip make the button more accessible in tight spaces. For a more secure hold than standard quick-release pins, they lock in place until you push the button 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.
316 stainless steel pins have the best corrosion resistance of our stainless steel pins. They may be mildly magnetic.
17-4 PH stainless steel pins are stronger than 316 stainless steel pins, but not as corrosion resistant. They are magnetic.
