S-90343A125 10-32 x 1/2" ASME B18.3 18-8 Stainless Steel Thread-Locking Socket Head Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with epoxy adhesive thread locker that maintains integrity across extreme temperature ranges (-60° to 300°F)
• Superior corrosion resistance through 18-8 stainless steel construction for extended service life in harsh environments
• Precision thread engagement with Class 3A fit ensuring reliable, consistent fastening in critical applications
• High-load capacity with 70,000 psi tensile strength and Rockwell B70 hardness for demanding mechanical assemblies
• Optimized torque transmission through 5/32" hex drive design preventing tool slippage and head stripping
• Full-thread engagement along the entire 1/2" length for maximum grip strength and load distribution
• Industry-standard compliance with ASME B18.3 specifications guaranteeing interchangeability and quality assurance

Professional Applications & Engineering Value

These 10-32 UNF socket head cap screws deliver exceptional engineering value in applications where vibration resistance and precision matter most. The epoxy adhesive thread locker chemically bonds to mating surfaces, creating permanent fastening solutions that eliminate the need for secondary locking mechanisms in machinery, automotive, and aerospace assemblies. The Class 3A thread fit provides tighter tolerances than standard fasteners, ensuring precise alignment in CNC equipment, precision instruments, and robotic systems. Manufactured from 18-8 stainless steel, these screws maintain structural integrity in corrosive environments while the fine thread spacing offers superior clamping force distribution compared to coarse thread alternatives. The combination of 70,000 psi tensile strength and fully threaded design makes them ideal for high-stress applications where fastener failure is not an option.

Specification Summary & Compliance

These precision fasteners feature Class 3A thread fit per UNF standards with 10-32 thread size and fine thread spacing. Manufacturing complies with ASME B18.3 specifications for dimensional accuracy and performance requirements. The epoxy adhesive thread locker begins hardening within 15 minutes and reaches full strength after 24 hours, providing permanent locking solution. Materials meet industry standards for 18-8 stainless steel composition with Rockwell B70 hardness and 70,000 psi tensile strength ratings.
