Key Features & Benefits at a Glance
- Exceptional tensile strength of 140,000 psi ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
- Class 3A thread fit provides superior precision and tighter tolerances for secure, vibration-resistant assemblies in demanding environments.
- Black-oxide coating on alloy steel offers enhanced corrosion resistance and durability, extending service life in harsh conditions.
- Ultra-low socket head profile allows for installation in confined spaces where clearance is limited, improving design flexibility.
- 5/32" hex drive ensures easy installation and removal with standard tools, minimizing assembly time and labor costs.
- Rockwell C32 hardness maintains structural integrity under heavy loads, preventing deformation and ensuring long-term reliability.
- Full threading along the 1" length enables consistent clamping force and versatility across various material thicknesses.
Professional Applications & Engineering Value
Engineered for precision and endurance, these 5/16"-18 UNC socket head cap screws are ideal for machinery, automotive, and aerospace applications where space constraints and high vibration are common challenges. The black-oxide alloy steel construction combats corrosion while the coarse thread design facilitates quick assembly in softer materials or where disassembly is frequent. With an ultra-low profile head and Class 3A thread fit, these screws deliver secure fastening in tight tolerances, reducing maintenance needs and enhancing operational safety in heavy-duty industrial settings.
Specification Summary & Compliance
This product adheres to UNC coarse thread standards with a Class 3A thread fit for precise engagement. Dimensions include a 1" length with a tolerance of -0.005" to 0.005", ensuring consistent performance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally conscious and regulated industrial use.
