The Jack Bolt Boss is a precision-engineered threaded boss designed for automotive mechanics and fabricators who need reliable mounting solutions for aftermarket components, sensors, and accessories on modern vehicles. This versatile threaded insert provides a clean, professional anchor point where factory mounting options don't exist, making it essential for serious vehicle modification work.
Built by U-B MACHINE (MPN 35-1100), the Jack Bolt Boss features a compact design that measures 2.15 x 1.6 x 3.75 inches and weighs just 0.38 lbs. Its precision-threaded design ensures repeatable, vibration-resistant connections—critical when mounting electronic sensors or mechanical components in high-vibration engine compartments where loose fittings can lead to sensor drift, electrical noise, or component failure.
Mechanics and performance enthusiasts use the Jack Bolt Boss across a wide range of applications, including custom gauge pods and turbo boost controllers. Its compact footprint allows integration into tight spaces where traditional welded or bolted solutions prove impractical, accommodating standard fasteners for secure, adjustable positioning without permanent modification to factory components.
