HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 375C 03 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 0.348-inch outside diameter (8.84 mm) with a 0.375-inch hole diameter (9.53 mm) and extends to a free length of 1.5 inch (38.1 mm), making it ideal for stamping and die applications. Made from Music Wire with a 0.065-inch wire diameter (1.65 mm), the spring delivers a spring rate of 96 lb/inch (16.813 N/mm) through its 12.31 active coils out of 14.31 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 0.92 inch (23.37 mm) while supporting a maximum load of 55.7 lb (247.77 N) at full compression. The spring has Squared and Ground ends and a Black Powder Coat finish for optimal die spring performance.
