Allen Head Body Bolt Kit - 1/4" ID, 1-1/4" OD Aluminum Washers with Serrated Nuts

Body bolts are mission-critical fasteners that demand precision and reliability—especially when vibration, weather, and track abuse are constantly testing your work. This Allen head body bolt kit eliminates guesswork with properly sized aluminum washers and serrated nuts that won't back out under load. Whether you're reassembling a fender after damage or building out a dirt late model from the ground up, having the right fasteners in stock saves time and ensures a professional, secure fit.

The serrated nuts grip the bolt threads mechanically, providing vibration resistance without relying on thread-locking compounds. The aluminum washers distribute clamping force evenly across body panels, preventing dimpling and stress concentration—critical for maintaining panel gaps and aerodynamic integrity on race cars. Available in practical pack sizes of 10, 25, or 50, you can stock what you need without excess inventory.
