HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 750AB 02 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 0.72-inch outside diameter (18.29 mm) with a 0.75-inch hole diameter (19.05 mm) and extends to a free length of 1.25 inch (31.75 mm), making it ideal for stamping and die applications. Made from Music Wire with a 0.115-inch wire diameter (2.92 mm), the spring delivers a spring rate of 240 lb/inch (42.032 N/mm) through its 4.73 active coils out of 6.73 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 0.8 inch (20.32 mm) while supporting a maximum load of 108 lb (480.41 N) at full compression. The spring has Squared and Ground ends and a Beige Powder Coat finish for optimal die spring performance.
