S-92865A757 9/16"-12 x 1" ASME B18.2.1, SAE J429 Medium-Strength Grade 5 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 120,000 psi ensures reliable performance in demanding applications, reducing the risk of fastener failure.
• Superior corrosion resistance from zinc plating extends service life and maintains integrity in harsh industrial environments.
• High hardness rating (Rockwell C25) provides excellent wear resistance and durability under repetitive stress.
• Coarse UNC thread design allows for quicker installation and better performance in materials prone to stripping or vibration.
• Class 2A thread fit ensures consistent, reliable engagement with standard nuts and tapped holes, minimizing assembly issues.
• Full threading along the 1" length offers maximum grip and adjustability, ideal for applications requiring secure fastening through varying material thicknesses.
• External hex drive design enables high-torque installation with common tools, speeding up assembly and maintenance processes.

Professional Applications & Engineering Value

This Grade 5 steel hex head screw is engineered to address critical challenges in heavy-duty industrial settings, such as machinery assembly, structural frameworks, and automotive components. The zinc plating provides a protective barrier against moisture and chemicals, significantly reducing corrosion-related failures in outdoor or high-humidity environments. Its UNC coarse thread and fully threaded design ensure rapid installation and secure holding power in soft materials or where vibration resistance is paramount. With a Rockwell C25 hardness and 120,000 psi tensile strength, it withstands extreme loads and repetitive stress, making it a reliable choice for construction, manufacturing, and equipment maintenance. The external hex drive allows for efficient tightening with standard wrenches, streamlining workflow and reducing labor time in B2B procurement scenarios.
