HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 750AB 08 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 0.7-inch outside diameter (17.78 mm) with a 0.75-inch hole diameter (19.05 mm) and extends to a free length of 3.5 inch (88.9 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 90 lb/inch (15.762 N/mm) through its 13.95 active coils out of 15.95 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 1.89 inch (48.01 mm) while supporting a maximum load of 144.9 lb (644.55 N) at full compression. The spring has Squared and Ground ends and a Beige Powder Coat finish for optimal die spring performance.
