S-92949A264 10-32 x 7/16" ASME B18.3 Stainless Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance through 18-8 stainless steel construction and passivated finish, ideal for harsh industrial environments
• Exceptional thread precision with Class 3A UNF fine threading ensures reliable, vibration-resistant connections in critical assemblies
• High mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness for demanding load-bearing applications
• Secure installation and removal using the 1/8" hex drive design, providing positive torque transfer without cam-out
• Optimized low-profile design with rounded button head that reduces snagging while maintaining generous bearing surface
• Full threading capability along the entire 7/16" length allows for maximum adjustment flexibility and grip length
• Regulatory compliance assurance meeting ASME B18.3 standards and environmental regulations including RoHS 3 and REACH

Professional Applications & Engineering Value

These 10-32 UNF Class 3A rounded head screws deliver exceptional engineering value in precision assemblies where vibration resistance and corrosion protection are critical. The 18-8 stainless steel material combined with passivated finish creates a robust barrier against chemical exposure and atmospheric corrosion, significantly extending service life in manufacturing equipment, electronic enclosures, and marine applications. The fine UNF threading with Class 3A fit provides superior engagement in tapped holes, minimizing loosening under dynamic loads. The hex drive design ensures reliable installation in confined spaces, while the rounded button head offers a finished appearance with reduced protrusion. These industrial fasteners solve common challenges of thread stripping, corrosion-induced failure, and installation inconsistency in B2B procurement scenarios.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 3A thread fit per UNF specifications, ensuring consistent engagement and optimal clamping force. The 10-32 thread size with fine pitch provides enhanced load distribution in materials with limited thickness. Full compliance with ASME B18.3 manufacturing standards guarantees dimensional accuracy and mechanical performance. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for global market acceptance.
