HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 750A 13A 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 0.71-inch outside diameter (18.03 mm) with a 0.75-inch hole diameter (19.05 mm) and extends to a free length of 6.5 inch (165.1 mm), making it ideal for stamping and die applications. Made from Music Wire with a 0.105-inch wire diameter (2.67 mm), the spring delivers a spring rate of 29.5 lb/inch (5.166 N/mm) through its 26.75 active coils out of 28.75 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 3.08 inch (78.23 mm) while supporting a maximum load of 102.7 lb (456.83 N) at full compression. The spring has Squared and Ground ends and a Gray Powder Coat finish for optimal die spring performance.
