The Extension Spring #73 (SRM73) is a durable spring steel extension spring designed for applications requiring reliable tension and return force. With a 13/16" outside diameter, 10-1/4" length, and .072 wire gauge, this spring provides consistent performance in mechanical assemblies, repair projects, and equipment requiring controlled tension. Manufactured from spring steel for strength and resilience, it’s built to stretch and return repeatedly under load—because a good extension spring should bounce back every time, even when the workload keeps pulling on it.
