S-92453A078 2-56 x 5/16" ASME B18.6.3 Brass Round Head Slotted Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from brass construction, ideal for humid or chemical-exposed environments
• High mechanical strength with 50,000 psi tensile rating and Rockwell B40 hardness for reliable load-bearing performance
• Precision thread engagement with Class 2A fit and UNC coarse spacing for quick assembly and vibration resistance
• Easy manual installation using standard slotted drive tools, reducing assembly time and tooling costs
• Full threading coverage along the 5/16" length ensures maximum grip strength in thin materials
• Regulatory compliance with RoHS 3 and REACH standards for safe use in regulated industries
• Standardized dimensions per ASME B18.6.3 guarantee interchangeability and consistent performance

Professional Applications & Engineering Value

These brass rounded head slotted screws deliver exceptional value in electrical enclosures, marine hardware, and precision instrumentation where corrosion resistance is critical. The UNC coarse thread design prevents cross-threading during high-speed assembly while maintaining secure fastening in softer materials. With fully threaded construction and Class 2A thread fit, these fasteners provide uniform stress distribution across the entire engagement length, eliminating weak points in vibration-prone applications. The combination of 50,000 psi tensile strength and non-magnetic properties makes them ideal for sensitive electronic equipment and corrosive industrial environments where steel fasteners would fail.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for precision assembly. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features UNC coarse threads (2-56) in right-hand direction with standard inch system measurements including 0.162" head diameter and 5/16" length.
