HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 1250C 07 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 1.195-inch outside diameter (30.35 mm) with a 1.25-inch hole diameter (31.75 mm) and extends to a free length of 4 inch (101.6 mm), making it ideal for stamping and die applications. Made from Oil Tempered Chrome Silicon with a 0.243-inch wire diameter (6.17 mm), the spring delivers a spring rate of 625 lb/inch (109.458 N/mm) through its 9.29 active coils out of 11.29 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 2.76 inch (70.1 mm) while supporting a maximum load of 775 lb (3447.37 N) at full compression. The spring has Squared and Ground ends and a Black Powder Coat finish for optimal die spring performance.
