S-90117A195 10-32 x 3/4" ASME B18.3 Alloy Steel Wire-Lockable Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Black-oxide coating on alloy steel provides enhanced corrosion resistance, extending service life in demanding industrial environments.
• Class 3A thread fit offers superior precision and tighter tolerances for secure, vibration-resistant connections in critical assemblies.
• Fine UNF threading delivers improved load distribution and better sealing capabilities compared to coarse threads.
• 5/32" hex socket drive allows for high-torque installation with standard tools, minimizing stripping and improving assembly efficiency.
• Fully threaded design enables consistent clamping force along the entire length, ideal for adjustable or deep-set applications.
• Rockwell C37 hardness provides excellent wear resistance, maintaining thread integrity through repeated use and disassembly.

Professional Applications & Engineering Value

This black-oxide alloy steel socket head cap screw is engineered to address common industrial fastening challenges where precision, strength, and durability are paramount. The 10-32 UNF fine thread configuration ensures superior engagement in tapped holes, reducing the likelihood of cross-threading in precision machinery, automotive components, and aerospace assemblies. The socket head design with hex drive facilitates installation in confined spaces where wrench clearance is limited, while the high tensile strength prevents elongation under load in heavy-duty applications. Ideal for manufacturing equipment, robotics, and structural frameworks, this screw maintains Class 3A thread fit accuracy for vibration-resistant connections that withstand dynamic operating conditions without loosening.
