HEFTY™ Die Spring Compression Springs

Heavy Duty Compression Springs

Lee Spring LHL 625B 12 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 0.585-inch outside diameter (14.86 mm) with a 0.625-inch hole diameter (15.88 mm) and extends to a free length of 8 inch (203.2 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 40 lb/inch (7.005 N/mm) through its 39.5 active coils out of 41.5 total coils, with Factory Option wind for predictable deflection behavior. The spring compresses to a solid height of 4.7 inch (119.38 mm) while supporting a maximum load of 145.706 lb (648.13 N) at full compression. The spring has Squared and Ground ends and a Purple Powder Coat finish for optimal die spring performance.
