HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 375D 04 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 0.354-inch outside diameter (8.99 mm) with a 0.375-inch hole diameter (9.53 mm) and extends to a free length of 1.75 inch (44.45 mm), making it ideal for stamping and die applications. Made from Music Wire with a 0.071-inch wire diameter (1.8 mm), the spring delivers a spring rate of 115 lb/inch (20.14 N/mm) through its 14.62 active coils out of 16.62 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 1.16 inch (29.46 mm) while supporting a maximum load of 67.9 lb (302.03 N) at full compression. The spring has Squared and Ground ends and a Orange Powder Coat finish for optimal die spring performance.
