Durable locking bolts designed for secure header installation.
The Proform Header Bolt is engineered for universal application with a 3/8 - 16 inch thread size and a length of 3/4 inch. Each bolt is equipped with a pair of specially designed wedge locking washers that enhance grip and prevent loosening due to vibration. When torqued to 28+ feet pounds, the hardened teeth of the washers bite into the bolt head and header surface, creating a secure locking mechanism that is resistant to rotation. This innovative design allows for easy removal and reuse, as the bolts can be untightened with a standard wrench and lubricated for future applications.
Constructed from high-quality steel and finished with a black oxide coating, these bolts are built to withstand the rigors of automotive environments. The wedge locking system eliminates the need for additional clips or retainers, simplifying the installation process. Furthermore, the performance of the locking mechanism is enhanced by the presence of oil, which facilitates the wedge effect, ensuring a reliable and long-lasting hold. Proform Header Bolts are an essential component for any header installation, providing both security and convenience.
