S-92941A714 1/2"-13 x 1 1/4" ASME B18.2.1 Brass Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from brass construction, ideal for humid or marine environments without compromising integrity
• High tensile strength of 50,000 PSI ensures reliable load-bearing capacity in demanding industrial applications
• Rockwell B55 hardness provides excellent durability and resistance to wear during repeated installations
• Class 2A thread fit guarantees smooth assembly and consistent engagement with standard nuts
• External hex drive with 3/4" head width allows for high-torque application using common wrenches
• Fully threaded 1-1/4" length offers maximum grip and adjustability across the entire fastener
• Compliance with ASME B18.2.1, RoHS 3, and REACH ensures regulatory adherence for global supply chains

Professional Applications & Engineering Value

This 1/2"-13 UNC brass hex head screw delivers exceptional performance in corrosive or electrically sensitive environments where steel fasteners would fail. The coarse threading and Class 2A fit prevent cross-threading during high-speed assembly, while the external hex drive provides superior torque transmission for tight sealing in plumbing, HVAC, and electrical enclosures. Engineers specify this fully threaded brass fastener for its combination of 50,000 PSI tensile strength and natural corrosion resistance, eliminating the need for additional plating or coatings in marine, chemical processing, and outdoor infrastructure applications.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 dimensional standards with Class 2A thread tolerances for consistent mating with UNC nuts. The 1/2"-13 coarse thread and fully threaded design ensure rapid installation. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and material traceability.
