HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 625A 09 is a heavy-duty die compression spring from the HEFTY™ Die Spring series, specifically engineered for demanding industrial applications requiring durabiliy and substantial load capacity. This spring features an 0.565-inch outside diameter (14.35 mm) with a 0.625-inch hole diameter (15.88 mm) and extends to a free length of 4 inch (101.6 mm), making it ideal for stamping and die applications. Made from Music Wire with a 0.09-inch wire diameter (2.29 mm), the spring delivers a spring rate of 44 lb/inch (7.706 N/mm) through its 20.87 active coils out of 22.87 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 1.99 inch (50.55 mm) while supporting a maximum load of 88.4 lb (393.22 N) at full compression. The spring has Squared and Ground ends and a Gray Powder Coat finish for optimal die spring performance.
