• Exceptional tensile strength of 70,000 psi ensures reliable performance under high-stress applications
• Precise Class 3A thread fit provides superior engagement and vibration resistance in critical assemblies
• Standard hex socket drive allows for high-torque installation with common 3/32" hex tools
• Full threading along the 1/2" length enables maximum adjustability and secure fastening depth
• Rockwell B70 hardness rating maintains thread integrity and prevents stripping during repeated use
• Right-hand coarse UNC threading ensures quick installation and compatibility with standard components

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these socket head cap screws combine the corrosion-resistant properties of 18-8 stainless steel with high-strength performance. The 5-40 UNC coarse thread configuration provides excellent engagement in various materials while resisting vibration-induced loosening. With a 70,000 psi tensile strength and Class 3A thread fit, these fasteners deliver reliable performance in machinery assembly, automotive components, and precision equipment where vibration resistance and corrosion protection are critical. The standard hex socket drive design enables flush mounting in confined spaces while accommodating high installation torque requirements.
