Key Features & Benefits at a Glance
- Exceptional strength and durability with 170,000 psi tensile strength and Rockwell C39 hardness, ideal for high-stress industrial environments.
- Superior corrosion resistance thanks to the black-oxide finish on both the alloy steel screw and washer, extending service life.
- Reliable, precision threading with Class 3A fit and 10-24 UNC coarse thread, ensuring secure fastening and vibration resistance.
- Enhanced load distribution via the integrated flat washer, reducing surface pressure and preventing material damage.
- Easy installation and removal with a 5/32" hex drive socket head, allowing for high torque application in confined spaces.
- Partially threaded design for precise clamping control, minimizing the risk of over-tightening.
- Compliance with industry standards including ASTM A574, RoHS 3, and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This black-oxide alloy steel socket head cap screw is engineered to address common industrial challenges such as vibration loosening, corrosion, and high tensile demands. The 10-24 UNC coarse thread and Class 3A thread fit provide excellent grip and reliability in dynamic applications, from machinery assembly to automotive components. The integrated flat washer distributes clamping force evenly, protecting softer materials and enhancing joint integrity. With a Rockwell C39 hardness and robust 170,000 psi tensile strength, it withstands heavy loads and harsh conditions, making it a trusted choice for engineers seeking durable, compliant fasteners that meet ASTM A574 specifications and environmental regulations like RoHS and REACH.
Specification Summary & Compliance
This socket head cap screw features precise Class 3A thread fit and 10-24 UNC coarse threads with a minimum thread length of 1-1/8". It is manufactured in accordance with ASTM A574 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring high dimensional accuracy and environmental safety for industrial use.
