Industrial Grade Garter Spring is a long, close coiled extension springs with the ends fastened together. The Garter Spring is used in the form of a ring to hold mechanical seals on a shaft. The Garter Spring can also be used to hold round segments together, or as driving belts such are often found in cameras, projection machines, and similar devices. The Industrial Grade Garter Spring ensures that a small screw can be inserted tightly in one end and the other end of the spring is reverse twisted so it winds itself onto the projecting end of the screw.
