HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 500A 8A 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 0.475-inch outside diameter (12.07 mm) with a 0.5-inch hole diameter (12.7 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 0.072-inch wire diameter (1.83 mm), the spring delivers a spring rate of 27.5 lb/inch (4.816 N/mm) through its 22.4 active coils out of 24.4 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 1.9 inch (48.26 mm) while supporting a maximum load of 61.696 lb (274.44 N) at full compression. The spring has Squared and Ground ends and a Gray Powder Coat finish for optimal die spring performance.
