Heavy Duty Compression Springs

Lee Spring LHL 375D 10 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 0.353-inch outside diameter (8.97 mm) with a 0.375-inch hole diameter (9.53 mm) and extends to a free length of 8 inch (203.2 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 26 lb/inch (4.553 N/mm) through its 65.37 active coils out of 67.37 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 5.46 inch (138.68 mm) while supporting a maximum load of 83.628 lb (372 N) at full compression. The spring has Squared and Ground ends and a Orange Powder Coat finish for optimal die spring performance.
