Euclid Inner Cap Nut
The Euclid Inner Cap Nut fits dual-mounted aluminum wheel service, where the inner wheel hardware has to clamp securely before the outer wheel hardware is handled. Its Grade 8, through-hardened build suits heavy wheel-end fastening where torque load, thread engagement, and repeated service removal all matter. The part’s 3.06-inch length and right-hand thread format matter because cap nuts sit deep in the wheel stack, where access and alignment affect final assembly. Wheel service can slow down when old cap nuts have rounded flats, damaged threads, or mixed hardware from earlier repairs. For Euclid E-5978-R, the inner wheel position gets a fastener built for aluminum dual wheel mounting.
