The standard OEM pin is prone to fracturing at the cross-hold location. This results from being made of high tensile, low alloy steel, quenched and tempered at 340-371 HB. Geographe developed the Enhanced Performance Wrench Pin to address this issue. It omits the cross-hold lubrication hole and is made from case-hardening alloy steel, gas-carburised with a core hardness of 400 HN and a surface hardness of 58+ HRC. The pin also undergoes heat treatment for improved strength, toughness, fatigue resistance, and wear properties. These enhancements make the Enhanced Performance Wrench Pin a valuable component for PV271 Drills.
