S-90117A187 10-24 x 1/2" 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 under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel extends service life and maintains integrity in harsh industrial environments.
• Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies, minimizing loosening in critical machinery.
• High hardness rating (Rockwell C37) offers excellent wear resistance, maintaining thread integrity through repeated use and installation.
• Standard hex socket drive (5/32") allows for easy installation with common tools while providing high torque capability without stripping.
• Fully threaded UNC coarse thread design enables faster assembly and superior holding power across the entire length of the screw.
• Compliance with major standards including ASME B18.3, RoHS 3, and REACH ensures quality, safety, and environmental responsibility for global supply chains.

Professional Applications & Engineering Value

Engineered for industrial applications requiring uncompromising reliability, these socket head cap screws solve critical fastening challenges in machinery, automotive, and heavy equipment. The black-oxide alloy steel construction combats corrosion while the Class 3A thread fit maintains precise alignment in vibration-prone assemblies. The 10-24 UNC coarse thread configuration provides rapid installation and superior resistance to loosening, making these fully threaded fasteners ideal for high-stress joints. With 170,000 PSI tensile strength and Rockwell C37 hardness, they withstand extreme mechanical loads without deformation, ensuring long-term operational safety in right-hand thread applications where failure is not an option.

Specification Summary & Compliance
