Description
Radlok 5.7mm Stud Adapter — M8x1.25 Female
A precision-machined stud adapter that converts any M8x1.25 threaded terminal into a Radlok 5.7mm quick-disconnect connection. Copper core with tin plating delivers high electrical conductivity with added oxidation resistance, keeping connection integrity intact over time. Threads directly onto M8x1.25 posts — including the B-series starter solenoid — and presents a 5.7mm Radlok-compatible stud for tool-free connect and disconnect without altering the host component. Suited to starter circuits, battery terminals, or any high-current M8x1.25 application.
Radlok is an Amphenol-engineered high-power press-lock connector originally developed for EV battery systems, heavy equipment, and aerospace — applications where connection failure isn’t an option. The connector uses RADSOK technology, a hyperbolic grid contact design that maximizes surface contact between pin and socket, resulting in significantly lower contact resistance than a traditional ring terminal or bolt-on lug. Less resistance means more of your electrical energy reaches the starter instead of being lost at the connection — translating directly to a stronger, more consistent crank. Thread the adapter onto your terminal, press the Radlok cable end onto the 5.7mm stud, and it locks in place with no tools required.
