S-97763A362 3/8"-16 x 1" ASME B18.3 Stainless Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from Black-Oxide 18-8 Stainless Steel construction, ideal for harsh environments.
• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing performance.
• Precise thread engagement with Class 3A thread fit, ensuring secure fastening and vibration resistance.
• Easy installation and removal using a standard 7/32" hex drive, reducing assembly time.
• Full threading along the 1" length provides maximum grip and uniform stress distribution.
• Coarse UNC thread spacing enables quick assembly and is less prone to clogging in dirty conditions.
• Compliance with ASME B18.3, RoHS 3, and REACH guarantees quality and environmental safety for industrial use.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these Black-Oxide 18-8 Stainless Steel Rounded Head Screws address common challenges like corrosion, vibration loosening, and high-stress fatigue. The button head design with a rounded profile offers a low-profile, snag-resistant finish, making them suitable for machinery, automotive assemblies, and outdoor equipment where clearance is limited. The Class 3A thread fit and coarse UNC threading ensure tight, reliable connections that withstand dynamic loads and thermal cycling. With a fully threaded shank and hex drive, they simplify maintenance and provide consistent clamping force, reducing the risk of joint failure in critical applications.

Specification Summary & Compliance

This screw features a 3/8"-16 UNC coarse thread with Class 3A precision tolerance for accurate fit. It meets ASME B18.3 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and reliability in industrial use.
