S-97715A141 8-32 x 1/4" ASME B18.3 Brass Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with brass construction, ideal for humid or chemically exposed environments
• Precise Class 3A thread fit ensures reliable engagement and reduces cross-threading risks in assembly
• High tensile strength (50,000 psi) provides exceptional load-bearing capacity for demanding applications
• Rockwell B55 hardness offers excellent durability and resistance to wear over repeated use
• Fully threaded UNC coarse spacing enables faster installation and stronger holding power in softer materials
• Hex drive (3/32") design allows for secure tool engagement and reduced cam-out during tightening
• Compliance with ASME B18.3, RoHS 3, and REACH guarantees industry-standard quality and environmental safety

Professional Applications & Engineering Value

These 8-32 UNC brass rounded head screws are engineered to address critical challenges in electrical enclosures, marine hardware, and plumbing systems where corrosion resistance and reliable fastening are paramount. The brass material naturally resists oxidation and galvanic corrosion, while the Class 3A thread fit and coarse thread spacing ensure vibration-resistant connections that maintain integrity under stress. The button head style with hex drive provides a low-profile, flush finish that minimizes snagging and allows for easy access in confined spaces. With fully threaded design and 50,000 psi tensile strength, these screws deliver consistent performance in assemblies requiring repeated disassembly and reassembly.

Specification Summary & Compliance
