• Easy installation and removal with a standard hex drive (3/32") and socket head design, allowing for high torque application in confined spaces.
• Broad compatibility with UNC coarse threading (4-40) and right-hand direction, making it suitable for a wide range of standard assemblies.
• Full-threaded design for maximum grip and holding power along the entire 3/32" length of the screw.
• Regulatory peace of mind with compliance to ASME B18.3, ASTM F837, RoHS 3, and REACH, ensuring safety and environmental standards are met.

Professional Applications & Engineering Value

This 4-40 UNC socket head cap screw is engineered to address critical challenges in precision assembly and machinery. The 18-8 stainless steel material offers excellent resistance to oxidation and corrosion, which is vital for components exposed to moisture, chemicals, or varying temperatures. Its Class 3A thread fit and coarse UNC threading provide a tighter, more reliable connection than standard fits, reducing the likelihood of thread stripping and ensuring long-term joint integrity in high-vibration environments like automotive, aerospace, and industrial equipment. The socket head with hex drive allows for efficient installation in tight spaces, enhancing assembly speed and maintenance workflows while the fully threaded design maximizes load distribution.
