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.
- 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.
- Coarse UNRC threading allows for quicker installation and easier alignment, saving time and labor in assembly operations.
- Partially threaded design combines the grip of threads with the strength of an unthreaded shank, ideal for precise clamping applications.
- 5/8" hex drive socket enables high-torque installation with standard tools, ensuring a tight, secure fit without stripping.
- Compliance with ASTM A574, RoHS 3, and REACH guarantees material consistency and environmental safety, meeting global industrial standards.
Professional Applications & Engineering Value
This black-oxide alloy steel socket head cap screw is engineered to address critical challenges in heavy machinery, automotive, and construction sectors. Its high tensile strength (170,000 psi) and Rockwell C37 hardness prevent deformation under extreme loads, while the coarse UNRC threads and Class 3A fit minimize loosening from vibrations. The partially threaded rod design provides optimal stress distribution, reducing the risk of fatigue in dynamic applications. Ideal for industrial assembly where reliability is paramount, this screw ensures long-term performance with its corrosion-resistant black-oxide finish, making it a top choice for engineers seeking durability and compliance with ASTM A574 specifications.
Specification Summary & Compliance
This socket head cap screw features precise Class 3A thread fit and UNRC coarse threading with a thread size of 3/4"-10 and minimum thread length of 2". It adheres to ASTM A574 manufacturing standards and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for industrial use.
