S-92451A714 1/2"-13 x 1 1/4" ASME B18.6.3 Brass Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to brass construction, ensuring long-term reliability in humid or corrosive industrial environments
• Exceptional tensile strength of 50,000 psi provides reliable fastening performance under significant mechanical stress
• Precision Class 2A thread fit guarantees smooth installation and secure connections with standard mating components
• 82° countersink angle with standard flat head profile enables flush mounting for clean, professional finishes
• Fully threaded 1-1/4" length offers maximum grip and holding power throughout the entire fastener engagement
• Rockwell B50 hardness rating maintains thread integrity and prevents deformation during repeated installations
• Slotted drive compatibility allows for quick installation with standard screwdrivers commonly available in maintenance kits

Professional Applications & Engineering Value

These brass flat head slotted screws with 1/2"-13 UNC coarse threading solve critical engineering challenges in applications where corrosion resistance and electrical conductivity are paramount. The combination of 50,000 psi tensile strength and Rockwell B50 hardness ensures reliable performance in electrical panels, marine hardware, and plumbing systems where exposure to moisture and chemicals would degrade standard steel fasteners. The fully threaded design provides maximum thread engagement in soft materials or thin-section components, while the standard 82° countersink creates seamless finishes in precision assemblies. These industrial brass screws maintain dimensional stability across temperature variations, making them ideal for instrumentation, HVAC systems, and manufacturing equipment requiring non-magnetic, non-sparking properties.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerances ensuring compatibility with standard UNC nuts and threaded holes. The 1/2"-13 UNC coarse thread profile provides optimal engagement in various materials while the right-hand threading follows industry standards. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for international industrial applications.
