The 58528-2 is a bottoming die component used in crimp tooling systems to guarantee proper crimp force application during wire terminal crimping. This die is engineered to control the compression and reduction of cross-sectional area of both wire and terminal, ensuring consistent crimp quality and repeatability. The tool operates with a handle force range of 40 to 47 lbs and achieves a crimp height between 38.18 and 498 units after crimping, with specified gage pin measurements for quality verification. The 58528-2 requires recertification every 8 months or 1,000 cycles to maintain long-term consistency and confirm that proper crimp force results in specified tensile strength, mechanical stability, and electrical conductivity. This bottoming die is essential for production environments requiring reliable, repeatable crimping operations that meet strict electrical and mechanical specifications.
