S-90357A126 8-32 x 5/8" Alloy Steel Ultra-Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional Tensile Strength - With 140,000 psi tensile strength, these screws provide superior load-bearing capacity and reliability in demanding applications
• Precision Thread Fit - Class 3A thread fit ensures tight tolerances and secure fastening with minimal backlash in critical assemblies
• Enhanced Corrosion Resistance - Black-oxide coating on alloy steel offers improved protection against rust and environmental degradation
• Space-Saving Design - Ultra-low profile socket head allows for installation in confined spaces where standard heads won't fit
• Consistent Performance - Rockwell C32 hardness maintains structural integrity and prevents deformation under stress
• Reliable Drive Engagement - 5/64" hex drive provides positive torque transmission and reduces stripping risk during installation
• Regulatory Compliance - Meets RoHS 3 and REACH standards for safe use in regulated industries and international markets

Professional Applications & Engineering Value

These 8-32 UNC thread socket head cap screws deliver critical engineering solutions where space constraints and high-strength requirements intersect. The ultra-low profile design enables installation in compact machinery, precision instruments, and electronic enclosures where conventional fasteners would protrude excessively. Manufactured from black-oxide alloy steel, these screws withstand harsh industrial environments while maintaining their protective coating integrity. The Class 3A thread fit ensures precise engagement in tapped holes, eliminating play in vibration-prone applications. With coarse thread spacing and right-hand threading, these fasteners provide rapid assembly in production environments while the fully threaded design offers maximum grip length for secure connections across various material thicknesses.

Specification Summary & Compliance

Precision-engineered to Class 3A thread fit standards with tight length tolerance of ±0.005" for consistent performance. Manufactured according to UNC thread specifications with 8-32 thread size and coarse thread spacing. These socket head cap screws feature a 5/64" hex drive and ultra-low profile head design. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors and international markets.
