S-92941A710 1/2"-13 x 3/4" ASME B18.2.1 Brass Hex Head Screws

Key Features & Benefits at a Glance

• Corrosion-resistant brass construction ensures long-lasting performance in humid or chemically aggressive environments, reducing replacement frequency and maintenance costs.
• High tensile strength of 50,000 psi provides reliable load-bearing capacity for demanding industrial assemblies, minimizing the risk of mechanical failure.
• Class 2A thread fit with UNC coarse threading offers faster installation and easier alignment, improving assembly efficiency and reducing labor time.
• External hex drive and hex head design allows for high-torque application with standard tools, ensuring secure fastening in high-vibration settings.
• Full threading along the 3/4" length maximizes grip and holding power across the entire fastener, enhancing joint integrity in varied material thicknesses.
• Rockwell B55 hardness maintains thread form and head integrity under repeated use, extending service life in cyclical load conditions.
• Compliance with ASME B18.2.1, RoHS 3, and REACH guarantees adherence to industry standards and environmental regulations, supporting global supply chain requirements.

Professional Applications & Engineering Value

This brass hex head screw is engineered to address common challenges in industrial settings, such as corrosion-induced degradation and assembly inefficiencies. The UNC coarse thread design enables quick installation in soft materials or pre-tapped holes, reducing cross-threading risks and speeding up production lines. Made from durable brass, it resists galvanic corrosion and is ideal for electrical enclosures, plumbing systems, and marine equipment where moisture exposure is frequent. The external hex drive and fully threaded body ensure uniform stress distribution, preventing loosening in high-vibration machinery. With a tensile strength of 50,000 psi and Rockwell B55 hardness, it withstands mechanical stresses in heavy-duty applications like pump assemblies or structural frameworks, delivering reliable performance while meeting ASME B18.2.1 specifications for dimensional consistency.

Specification Summary & Compliance

This screw adheres to precise Class 2A thread fit tolerances under the UNC coarse thread standard, ensuring compatibility with corresponding nuts and threaded holes. Manufacturing follows ASME B18.2.1 for dimensional accuracy, including a 1/2"-13 thread size, 3/4" length, and external hex drive configuration. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for safe use in industrial and consumer products.
