Description
This is the HILLMAN #61 Extension Spring, designed for applications that require a precisely sized extension spring with a .035-inch wire. Someone needing a #61 spring will choose this model for its zinc-plated finish and consistent spring dimensions, ensuring it matches the specifications required for replacement or assembly. The zinc plating gives the spring a durable metal coating while the .035 in wire size defines its thickness for predictable tension characteristics. Use it when an accurately sized extension spring is called for in mechanical linkages, hardware repairs, or restoration projects where the correct spring number and construction matter. The HILLMAN name and the clear spring number make identifying and matching this component straightforward.
