S-92941A726 1/2"-13 x 3 1/2" ASME B18.2.1 Brass Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from high-quality brass construction, ideal for harsh industrial environments
• Exceptional mechanical strength with 50,000 psi tensile rating and Rockwell B55 hardness for reliable load-bearing performance
• Optimized torque transmission through external hex drive and 3/4" head width for secure installation
• Precision thread engagement with Class 2A UNC coarse threads ensuring consistent fastening in various materials
• Controlled thread engagement through partial threading design preventing over-tightening in deep applications
• Regulatory compliance assurance meeting ASME B18.2.1 standards and environmental regulations (RoHS 3, REACH)
• Versatile industrial compatibility with right-hand coarse threading suitable for multiple assembly applications

Professional Applications & Engineering Value

This brass hex head screw delivers critical performance advantages in demanding industrial settings where corrosion resistance and mechanical reliability are paramount. The UNC coarse thread configuration provides superior holding power in soft materials and faster installation times, while the partial threading design prevents cross-threading in deep-set applications. Engineered with 50,000 psi tensile strength and Rockwell B55 hardness, this fastener maintains structural integrity under vibration and load stress. The external hex drive with substantial head dimensions ensures maximum torque application without stripping, making it ideal for heavy equipment, marine components, and electrical enclosures where brass's non-sparking properties and environmental resistance are essential.

Specification Summary & Compliance

This 1/2"-13 UNC brass hex head screw features precision Class 2A thread fit tolerances with coarse thread spacing, measuring 3 1/2" in length with minimum thread length of 1 1/4". Manufactured in compliance with ASME B18.2.1 specifications for dimensional accuracy and performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial applications.
