HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 1250D 01 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 1.205-inch outside diameter (30.61 mm) with a 1.25-inch hole diameter (31.75 mm) and extends to a free length of 2 inch (50.8 mm), making it ideal for stamping and die applications. Made from Oil Tempered Chrome Silicon with a 0.25-inch wire diameter (6.35 mm), the spring delivers a spring rate of 1625 lb/inch (284.591 N/mm) through its 3.97 active coils out of 5.97 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 1.5 inch (38.1 mm) while supporting a maximum load of 812.5 lb (3614.18 N) at full compression. The spring has Squared and Ground ends and a Orange Powder Coat finish for optimal die spring performance.
