Studs and bolts are made from high-quality premium steels that are domestically melted. The steel bars are cold worked to enhance mechanical properties and eliminate surface impurities. OptiTorque fasteners undergo a proprietary heat treatment process, allowing them to achieve higher tensile strengths while maintaining toughness. The fasteners are centerless ground to ensure concentricity and remove any surface defects from heat treating. Threads are roll formed on the hardened fasteners. After threading, the fasteners are stress relieved, deburred, and plated or polished to meet each customer's packaging requirements.\u003c\/p\u003e","brand":"OptiTorque","offers":[{"title":"Default Title","offer_id":51607061365034,"sku":"10392P","price":624.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0912\/1851\/0122\/files\/ProductImage_30.png?v=1780064877","url":"https:\/\/pml-parts.ca\/products\/1989-1998-cummins-5-9l-optitorque-patriot-head-stud-kit-10392p","provider":"PML Parts","version":"1.0","type":"link"}
