Radlok 5.7mm Stud — m8x1.2 Male

Radlok 5.7mm Stud — M8x1.25 Male

A Racing History Company manufactured Radlok 5.7mm stud with an M8x1.25 male thread. Copper core with tin plating delivers high electrical conductivity with added oxidation resistance, keeping connection integrity intact over time. Threads directly into any M8x1.25 tapped location — chassis grounding points, engine block threads, transmission cases, or factory body locations — and presents a 5.7mm Radlok-compatible stud for a press-lock high-current connection.

Radlok is an Amphenol-engineered connector system originally developed for EV battery systems, heavy equipment, and aerospace — applications where connection integrity is critical. Using RADSOK hyperbolic grid contact technology, it maximizes surface contact between pin and socket, resulting in significantly lower resistance than a traditional ring terminal or bolt-on lug. Less resistance means more of your electrical energy reaches its destination instead of being lost at the connection.

Traditional terminals are one of the most overlooked failure points on a built car. Rings stretch, nuts back off from vibration, and the resulting intermittent contact is one of the leading causes of no-start conditions that take hours to diagnose. Thread this stud into your existing M8x1.25 hole, press the Radlok cable end on, and the connection locks in place — resistant to loosening, resistant to corrosion buildup, and reliable every time.
