A Garter Spring is either a helical Compression Spring (space between coils) or a helical Extension Spring (close wound coils) that is coiled in a length, with both ends connected to form a ring or circle. Garter Springs are most commonly manufactured with ends that have hooks that assemble together, or with one end tapered to screw into the other end. A Garter Spring that has space between coils is used in applications where a radial expansion (outwards) force is necessary, whereas a Garter Spring that has close wound coils is used in applications where a radial contracting (inwards) force is required; this is mostly dependent on the application.
Spring steels most commonly used in our process for manufacturing Garter Springs are Music and Stainless Steel wire. Our Garter Spring manufacturing capacity typically ranges in wire diameters from .020″ up to .105″, with many of our prototype and short run orders ranging within these sizes.
