HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 375B 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 0.335-inch outside diameter (8.51 mm) with a 0.375-inch hole diameter (9.53 mm) and extends to a free length of 7 inch (177.8 mm), making it ideal for stamping and die applications. Made from Music Wire with a 0.058-inch wire diameter (1.47 mm), the spring delivers a spring rate of 13 lb/inch (2.277 N/mm) through its 61.44 active coils out of 63.44 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 4.1 inch (104.14 mm) while supporting a maximum load of 43.17 lb (192.03 N) at full compression. The spring has Squared and Ground ends and a Purple Powder Coat finish for optimal die spring performance.
