S-97715A572 5/16"-24 x 1 1/2" Brass Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with brass construction, ideal for harsh environments and moisture-prone applications
• Exceptional tensile strength of 50,000 psi ensures reliable, long-lasting fastening under high-stress conditions
• Precision Class 3A thread fit provides tighter tolerances for secure, vibration-resistant connections in critical assemblies
• Fine UNF threading (5/16"-24) offers enhanced grip and load distribution compared to coarse threads
• Fully threaded design maximizes engagement along the entire length for uniform clamping force
• Hex drive compatibility (3/16") allows for easy installation and high torque application with standard tools
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and global market accessibility

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these brass rounded head screws combine Rockwell B55 hardness with excellent machinability, making them ideal for electrical enclosures, marine equipment, and plumbing systems where corrosion resistance is critical. The 5/16"-24 UNF fine thread and Class 3A fit minimize backlash and prevent loosening under vibration, while the button head profile provides a low-profile, aesthetically pleasing finish. Their fully threaded design ensures consistent performance in assemblies requiring uniform pressure distribution, reducing the risk of joint failure in precision machinery and automotive components.

Specification Summary & Compliance

This screw adheres to UNF thread standards with a Class 3A thread fit for high-precision applications, featuring a right-hand thread direction and fine thread spacing. Manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloys and REACH (EC 1907/2006) SVHC compliance as of January 17, 2023, ensuring regulatory adherence for international industrial use.
