Key Features & Benefits at a Glance
- Permanent vibration resistance with integrated nylon patch thread locker, preventing loosening in dynamic applications from -70° to 250°F.
- Exceptional tensile strength of 170,000 psi ensures reliable performance under high-stress conditions in industrial machinery.
- Superior corrosion protection from the black-oxide finish, extending service life in demanding environments.
- Precise Class 3A thread fit provides secure, accurate fastening with minimal risk of cross-threading or play.
- Easy installation and removal using a standard 9/64" hex key, reducing assembly time and tool wear.
- Full thread engagement along the 1" length allows for consistent clamping force across various material thicknesses.
- Compliance with major standards including ASME B18.3 and ASTM A574, ensuring quality and interchangeability.
Professional Applications & Engineering Value
These black-oxide alloy steel socket head cap screws are engineered to address critical challenges in industrial assembly, such as vibration-induced fastener failure and thermal cycling. The nylon patch thread locker provides a permanent locking mechanism without requiring additional adhesives, ideal for UNC coarse threads in machinery, automotive, and aerospace components. With a Rockwell C37 hardness and high tensile strength, they resist deformation under load, while the socket head design allows for compact installations in confined spaces. This combination of material durability and thread locking technology ensures long-term reliability in temperature-varying environments, reducing maintenance needs and downtime.
Specification Summary & Compliance
This screw features an 8-32 UNC thread with Class 3A fit for precise tolerance, coarse thread spacing, and a right-hand thread direction. It meets ASME B18.3 specifications and ASTM A574 material standards, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for global industrial use.
