Key Features & Benefits at a Glance
- Superior tensile strength of 140,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
- Precision Class 3A thread fit guarantees smooth installation and secure fastening, minimizing assembly time and improving joint integrity.
- Low-profile socket head design allows for use in confined spaces where standard head height is prohibitive, enhancing design flexibility.
- Black-oxide coating on alloy steel provides excellent corrosion resistance, extending service life in various industrial environments.
- Fully threaded body offers consistent engagement along the entire length, ensuring uniform clamping force and vibration resistance.
- High hardness (Rockwell C39) resists wear and deformation, maintaining dimensional stability through repeated use and torque applications.
- Compliance with ASTM A574 assures material quality and manufacturing consistency, meeting rigorous industry standards for socket head cap screws.
Professional Applications & Engineering Value
Engineered for industrial applications requiring robust fastening solutions, this low socket head cap screw combines black-oxide alloy steel construction with a Class 3A UNC coarse thread to address common challenges like space constraints and vibration-induced loosening. The fully threaded design ensures maximum grip in machinery, automotive assemblies, and structural frameworks, while the hex drive allows for high-torque installation without slippage. Its high tensile strength and hardness make it ideal for heavy-duty equipment, reducing maintenance needs and enhancing operational reliability in harsh conditions.
Specification Summary & Compliance
This product adheres to ASTM A574 specifications, with precise Class 3A thread fit and UNC coarse threading for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets.
