Spring Pin
Shanghai Metal Corporation is a leading Spring Pin manufacturer and supplier.
A spring pin (also called tension pin or roll pin) is a mechanical fastener that secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the hole diameter, and a chamfer on either one or both ends to facilitate starting the pin into the hole. The spring action of the pin allows it to compress as it assumes the diameter of the hole. The force exerted by the pin against the hole wall retains it in the hole, therefore a spring pin is considered a self retaining fastener.
Spring pins may be used to retain a shaft as a journal in a plain bearing, as a type of key to fasten one shaft to another, or to precisely fasten flat faces of mating parts together through symmetric hole locations.
The most corrosion resistant slotted spring pins we offer. Also known as roll, tension, split, and expansion pins, the slot is pressed closed when the pins are inserted and does not flex after installation. The pins may be mildly magnetic and the ends are beveled or rounded to aid insertion. They are commonly used for fastening, pivoting, and holding.
Because spring pins are larger than the hole into which they're installed, they are held in place by tension against the hole wall. The actual diameter is slightly larger than the diameter shown, allowing pins to fit tightly when installed. For the best fit, your hole should be equal to or slightly larger than the diameter shown.
