Caliper Bolts (Pair) Hardened

The Caliper Bolts (Pair) Hardened by HOWE are purpose-built fasteners engineered for brake system assembly and maintenance on GM vehicles. These bolts secure brake calipers to mounting brackets with precision and durability, making them essential for any technician or operator performing brake service, restoration, or tactical vehicle maintenance. Available for sale as a matched pair, these hardened steel bolts meet OEM specifications and deliver the reliability demanded in both civilian and professional automotive environments.

Constructed from cadmium-plated hardened steel, the Caliper Bolts feature a 3/8-16 inch thread pitch with a 4.75-inch length and 5/8-inch hex head for wrench engagement. The built-in shoulder design prevents over-tightening and ensures consistent clamping load, a critical factor in brake system safety and performance. Cadmium plating provides superior corrosion resistance and lubricity, reducing galling during installation and extending service life in harsh conditions. The hardened steel composition resists stripping and fatigue, maintaining bolt integrity under repeated thermal cycling inherent to brake system operation.

Mechanics, fleet operators, and tactical vehicle maintenance teams rely on OEM-specification fasteners to ensure brake system reliability and safety compliance. This pair is compatible with GM brake caliper mounting applications where 3/8-16 inch fasteners are required. Whether performing routine service, upgrading brake components, or maintaining specialty vehicles, these hardened bolts deliver the precision fit and durability that prevents brake system failure. Installation requires a standard 5/8-inch wrench or socket, and proper torque specifications should be observed per manufacturer guidelines.
