Advanced locking technology for secure exhaust header installation.
The Proform Header Bolt is designed for universal application with a 3/8 - 16 inch thread size and a length of 3/4 inch. This bolt features a hex head and is constructed from durable steel with a black oxide finish, ensuring longevity and resistance to corrosion. Each bolt is permanently assembled with a pair of special wedge locking washers that enhance its performance by providing a secure grip against loosening due to vibration.
The innovative wedge locking mechanism allows for easy installation and removal, as the bolts can be untightened with a standard wrench, lubricated, and reused without the need for additional clips or retainers. The unique design utilizes tension rather than friction, which means that oil can actually improve the locking effect, making these bolts highly effective in maintaining a secure fit under various conditions. This set of 12 bolts is an essential component for any exhaust header installation, providing reliability and ease of use.
