Key Features & Benefits at a Glance
- Exceptional tensile strength of 180,000 psi ensures reliable performance under high-stress industrial conditions, reducing the risk of fastener failure.
- Class 3A thread fit provides superior precision and tighter tolerances for secure, vibration-resistant assemblies in demanding applications.
- Black-oxide finish on alloy steel enhances corrosion resistance and durability, extending service life in harsh environments.
- Integrated split lock washer prevents loosening from vibration, maintaining clamp load and assembly integrity over time.
- Rockwell C39 hardness offers excellent wear resistance, ensuring the screw retains its form and function through repeated use.
- Coarse UNC threading allows for quicker installation and easier alignment, saving time in high-volume production settings.
- Full threading enables consistent engagement along the entire length, providing uniform load distribution and enhanced holding power.
Professional Applications & Engineering Value
This 8-32 UNC Socket Head Cap Screw is engineered to address common industrial challenges such as vibration-induced loosening and material fatigue. The black-oxide alloy steel construction, combined with a Rockwell C39 hardness, ensures long-term durability in machinery, automotive, and heavy equipment applications where exposure to dynamic loads is frequent. The inclusion of a split lock washer directly counters vibrational stresses, making it ideal for assemblies requiring maintained torque and security. Its coarse thread spacing and Class 3A fit facilitate rapid, precise installation, reducing downtime in production lines while providing reliable, high-strength fastening solutions for critical components.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a precise Class 3A thread fit for accurate engagement. It is manufactured from alloy steel with a black-oxide surface treatment and includes a split lock washer of the same finish. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety standards for industrial use.
