Hot Rods Crank Pin - 8 x 20 x 45

This is the Hot Rods Crank Pin, measuring 8 x 20 x 45 millimeters. It's crafted from hot-rolled ASTM 4115 steel, a strong material chosen for its reliability in engine components. The pin is then case-hardened to a hardness of 58-62 Rc, which significantly increases the surface durability and resistance to wear.

This hardening process is crucial for parts like crankshaft pins that experience constant stress and friction during engine operation. By making the outer surface harder, it can better withstand the forces involved, helping to ensure the longevity of your engine's rotating assembly. The specific dimensions of 8 x 20 x 45mm mean it's designed for a precise fit within its intended application.
