Innovative design prevents loosening from vibrations for reliable performance.

Proform Wedge-Locking Header Bolts are engineered to provide a secure fastening solution for exhaust systems. These bolts feature a unique wedge-locking technology that eliminates the need for constant re-tightening of collector bolts, addressing a common issue caused by vehicle vibrations. The super-hardened external teeth of the wedge-locking washers grip the bolt head and flange surface, ensuring a snug fit that remains intact even under challenging conditions.

Constructed from Grade 8 steel with a black oxide finish, these bolts are designed for durability and longevity. Each set includes twelve hex head bolts with a 3/8-16 thread size and a length of 1 inch, making them suitable for universal applications. The installation process is straightforward, requiring only a standard wrench for both installation and removal, and they can be reused after lubrication.

The Proform Wedge-Locking Header Bolts are an essential component for maintaining the integrity of exhaust systems, providing a reliable solution that minimizes the risk of loosening due to vibrations. Their robust construction and innovative design make them a valuable addition to any automotive toolkit.
