S-92323A585 6-32 x 1/2" IFI 111, SAE J429 Medium-Strength Grade 5 Steel Serrated-Flange Hex Head Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for longer service life in harsh environments
• Superior load-bearing capacity with Grade 5 classification and 110,000 PSI tensile strength for demanding applications
• Secure anti-rotation locking provided by serrated flange design that eliminates need for separate washers
• Optimized thread engagement with Class 2A thread fit and coarse UNC threading for faster assembly and vibration resistance
• Reliable hardness performance with Rockwell C22 rating ensuring consistent durability under repeated torque applications
• Full-length threading enables maximum grip length and uniform stress distribution across the entire fastener
• Industry-standard compatibility with external hex drive design for use with common wrenching tools

Professional Applications & Engineering Value

These Grade 5 hex head screws deliver exceptional engineering value for industrial assembly applications where vibration resistance and structural integrity are critical. The zinc-plated steel construction provides essential corrosion protection for machinery, equipment frames, and structural components exposed to moderate environmental conditions. The combination of coarse 6-32 UNC threading with Class 2A tolerance ensures rapid installation while maintaining precise thread engagement, significantly reducing assembly time in production environments. The integrated flange with serrations creates a permanent locking mechanism that prevents loosening under dynamic loads, making these fully threaded screws ideal for automotive components, industrial machinery, and heavy equipment where vibration is a constant challenge.

Specification Summary & Compliance

This hex head screw features precise Class 2A thread fit with 6-32 UNC coarse thread specification and right-hand thread direction. Manufacturing complies with SAE J429 standards (IFI 111) for Grade 5 mechanical properties, ensuring consistent 110,000 PSI tensile strength and Rockwell C22 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications with strict material restrictions.
