HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 1250B 09 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 1.14-inch outside diameter (28.96 mm) with a 1.25-inch hole diameter (31.75 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 0.207-inch wire diameter (5.26 mm), the spring delivers a spring rate of 255 lb/inch (44.659 N/mm) through its 12.74 active coils out of 14.74 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 3.065 inch (77.85 mm) while supporting a maximum load of 493.4 lb (2194.75 N) at full compression. The spring has Squared and Ground ends and a Purple Powder Coat finish for optimal die spring performance.
