Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
- Black-oxide coating on alloy steel provides enhanced corrosion resistance, extending service life in harsh environments.
- Class 3A thread fit with UNC coarse threads delivers precise, secure engagement for vibration-resistant assemblies and easier alignment.
- Fully threaded design and 5" length offer consistent clamping force along the entire shank, ideal for thick materials or adjustable setups.
- Hex socket drive (3/8") and standard head profile enable easy installation with common tools, minimizing assembly time and tool slippage.
- Rockwell C37 hardness maintains durability under repeated loads, preventing deformation and ensuring long-term fastener integrity.
- Compliance with ASTM A574, RoHS 3, and REACH guarantees material consistency and environmental safety for global supply chain requirements.
Professional Applications & Engineering Value
Engineered for demanding settings, these socket head cap screws combine black-oxide alloy steel and UNC coarse threads to address common industrial challenges like vibration loosening and corrosion. The Class 3A thread fit ensures tight tolerances for secure fastening in machinery, automotive, and construction assemblies, while the fully threaded rod type allows uniform stress distribution across joints. With a 170,000 psi tensile strength and Rockwell C37 hardness, they resist wear in high-load scenarios, reducing maintenance needs. Ideal for industrial fasteners in equipment frames or structural supports, they provide a reliable, corrosion-resistant solution that meets rigorous engineering standards.
Specification Summary & Compliance
This screw features a 1/2"-13 UNC coarse thread with Class 3A fit for precise dimensional accuracy, adhering to ASTM A574 manufacturing specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability in professional use.
