HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 750C 06 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 2.5 inch (63.5 mm), making it ideal for stamping and die applications. Made from Oil Tempered Chrome Silicon with a 0.142-inch wire diameter (3.61 mm), the spring delivers a spring rate of 330 lb/inch (57.794 N/mm) through its 9.67 active coils out of 11.67 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 1.67 inch (42.42 mm) while supporting a maximum load of 273.9 lb (1218.37 N) at full compression. The spring has Squared and Ground ends and a Black Powder Coat finish for optimal die spring performance.
