It uses a single nut design with a spring steel keeper to lock onto the spindle while maintaining correct wheel bearing preload under high torque loads. With a 3.48 in-12 thread and an eight-point 4.813 in hex, it suits common TP trailer and Pro-Par axle spindles and is installed using a matching heavy-duty socket. The nut is heat-treated for strength and wear resistance in demanding road transport service. It is compatible with HM518445 \/ HM518410 outer bearing cup and cone sets and is widely applied on Fruehauf, Meritor, Dana Spicer, Hendrickson and Ingersoll axles. This construction supports accurate wheel end adjustment, helps prevent over-tightening and bearing damage, and provides reliable wheel retention on trucks and trailers in fleet and workshop applications.","brand":"STEMCO","offers":[{"title":"Default Title","offer_id":49057061306619,"sku":"ZST4474723","price":149.89,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/6030\/4123\/files\/40679.jpg?v=1783511893","url":"https:\/\/www.tranzmile.com\/products\/axle-nut-pro-torq-saf-hp-zst4474723","provider":"Tranzmile Truck \u0026 Trailer Parts","version":"1.0","type":"link"}
