The plate features two counterbored mounting holes that accommodate M14 fasteners, allowing for secure attachment to the chassis or suspension mount using standard hardware.
The counterbored design allows the fastener heads to sit flush with the plate surface, preventing interference with mating components and providing a clean, compact installation.
The plate’s geometry is optimised to provide a large contact area that distributes impact forces over a wide surface, reducing the risk of localised deformation or indentation.
Chamfered edges and a smooth transition radius at the corners prevent stress risers that could lead to cracking under repeated impact loading.
The 332106416 Stop Plate undergoes a comprehensive heat treatment process to achieve the optimal balance of hardness, toughness, and wear resistance.
The plate is through‑hardened to a hardness of 45–50 HRC, providing excellent resistance to plastic deformation and impact damage.
The hardening process is carefully controlled to ensure uniform hardness throughout the plate’s cross‑section, preventing soft spots that could lead to premature wear or failure.
Following heat treatment, the plate is finished with a zinc‑nickel plating that provides exceptional corrosion resistance, followed by a black oxide coating that enhances lubricant retention and provides a low‑friction surface.
The zinc‑nickel plating offers over 500 hours of salt spray resistance, ensuring the plate remains free from rust and corrosion even in the most aggressive environments.
The black oxide finish also provides a degree of self‑lubrication, reducing friction during contact and extending the life of both the stop plate and the mating stop surface.
