HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 750B 11 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 0.655-inch outside diameter (16.64 mm) with a 0.75-inch hole diameter (19.05 mm) and extends to a free length of 5 inch (127 mm), making it ideal for stamping and die applications. Made from Oil Tempered Chrome Silicon with a 0.125-inch wire diameter (3.18 mm), the spring delivers a spring rate of 104 lb/inch (18.214 N/mm) through its 22.67 active coils out of 24.67 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 3.1 inch (78.74 mm) while supporting a maximum load of 197.6 lb (878.97 N) at full compression. The spring has Squared and Ground ends and a Purple Powder Coat finish for optimal die spring performance.
