S-92196A755 5-40 x 1 1/8" ASME B18.3 18-8 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for reliable, high-stress applications
• Precise, secure fastening ensured by Class 3A thread fit, minimizing the risk of loosening under vibration
• Optimized for high-torque installation using a standard 3/32" hex drive, providing a secure, non-slip engagement
• Versatile partial threading design allows for precise clamping control and alignment in assemblies
• Guaranteed dimensional consistency and interchangeability through compliance with the ASME B18.3 standard
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives

Professional Applications & Engineering Value

This 5-40 UNC thread socket head cap screw is engineered to solve critical challenges in precision assembly and machinery. The 18-8 Stainless Steel material provides excellent resistance to oxidation and corrosion, extending service life in demanding conditions like manufacturing equipment, automotive subsystems, and outdoor enclosures. The coarse UNC thread and Class 3A fit enable rapid, reliable installation with high resistance to vibrational loosening, a common failure point in dynamic systems. The partially threaded shank and 1-1/8" length offer design flexibility, allowing engineers to securely fasten components where full threading is unnecessary or could weaken the joint. Its socket head design is ideal for applications with limited clearance, providing a flush profile while accommodating high torque via the 3/32" hex drive.

Specification Summary & Compliance

This fastener adheres to Class 3A thread fit for superior precision and a tight, secure assembly. It is manufactured in accordance with the ASME B18.3 specification, ensuring dimensional accuracy and interchangeability. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for hazardous substances.
