Prime‑Line® spring pins provide strong, flexible fastening for applications that require secure alignment and vibration resistance. Also known as roll pins, these hollow, slotted pins compress during installation and expand inside the hole to create a tight, self‑retaining fit without the need for threads or additional hardware. Ideal for use in machinery, tools, appliances, lawn and garden equipment, hinges, and mechanical assemblies, Prime‑Line spring pins help hold components in position while allowing slight movement to absorb shock and reduce wear. Designed for easy installation into properly sized drilled holes, they can be installed with basic hand tools or a hammer and punch. Manufactured from quality materials for durability and consistent performance, Prime‑Line spring pins make it easy to complete assemblies and repairs with reliable, long‑lasting results trusted by DIY homeowners and professionals across the U.S.
