Spring pins are a type of wire fastener that's widely used across industries. Spring pins secure, or fasten, two components together by compressing into a small diameter hole or slit. They may also be described as hollow press-fit fasteners. MW offers slotted spring pins that are hollow, cylindrical tubes with an end-to-end slot that allows for easier installation. Spring pins are also known as roll pins, split pins, tension pins, and C-pins.
We have several sizes and types of spring pins in stock as well as offering custom build-to-spec services for your spring pin design.
