HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 750AB 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 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 inch (76.2 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 102 lb/inch (17.864 N/mm) through its 12.31 active coils out of 14.31 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 1.76 inch (44.7 mm) while supporting a maximum load of 126.5 lb (562.7 N) at full compression. The spring has Squared and Ground ends and a Beige Powder Coat finish for optimal die spring performance.
