Professional Applications & Engineering Value
This heavy-duty hex head screw in 450 Stainless Steel is engineered to address critical challenges in industrial fastening, such as corrosion, high tensile loads, and vibration loosening. The UNC coarse thread and Class 2A thread fit provide secure, rapid assembly in structural frameworks, machinery, and equipment where reliability is paramount. The partially threaded design with an integrated flange distributes clamping force evenly, reducing the risk of joint failure. With a tensile strength of 170,000 psi and excellent hardness, it withstands extreme conditions in construction, automotive, and manufacturing sectors, ensuring minimal maintenance and extended service life.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a Class 2A thread fit for precise dimensional accuracy. It meets industry specifications for inch system fasteners, including head dimensions (9/16" width, 15/32" height) and flange diameter (27/32"). Manufactured from 450 Stainless Steel, it complies with common industrial requirements for material performance and is suitable for applications demanding high strength and corrosion resistance, aligning with standards like ASME for mechanical fasteners.
