• Precise and secure fastening ensured by the Class 3A thread fit and 1/4"-28 UNF fine thread, minimizing the risk of loosening.
• Optimized for high-torque applications with a standard socket head and 3/16" hex drive for easy installation in confined spaces.
• Versatile partial threading on a 2" length allows for a combination of clamping and alignment functions.
• Compliance with major environmental regulations, being RoHS 3 and REACH compliant for use in regulated industries.
• Right-hand thread direction for standard, intuitive assembly and disassembly processes.

Professional Applications & Engineering Value

This 316 Stainless Steel Socket Head Cap Screw is engineered to solve critical challenges in demanding industrial settings. Its core value lies in the combination of high corrosion resistance from the 316 material and passivated finish, making it ideal for applications exposed to chemicals, moisture, and marine environments. The Class 3A UNF fine thread provides a superior, vibration-resistant fit compared to coarse threads, which is crucial in precision machinery, automotive assemblies, and aerospace components where safety and reliability are paramount. The socket head design with a hex drive allows for high torque application in tight spaces, a common pain point in complex equipment assembly and maintenance. This fastener delivers long-term durability and strength, reducing maintenance frequency and failure risks in critical industrial fastening applications.
