S-92991A829 10-32 x 1/2" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to brass construction, ideal for harsh environments and electrical applications
• Exceptional thread precision with Class 3A fit ensures reliable, vibration-resistant assemblies and reduces the risk of cross-threading
• Maximum gripping power from the cup point design, which bites into shafts for secure positioning of components
• Optimized durability with Rockwell B55 hardness, providing excellent wear resistance without compromising on machinability
• Easy installation in confined spaces using the 3/32" hex drive and headless design, saving time during assembly
• Guaranteed mechanical reliability as it conforms to the stringent dimensional requirements of ASME B18.3
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental standards

Professional Applications & Engineering Value

This 10-32 UNF Class 3A brass set screw is engineered to address common challenges in precision assemblies, such as loosening under vibration and corrosion in sensitive environments. The fine thread and headless cup point design provide a firm, lasting grip on shafts and collars, preventing slippage in machinery and electronic enclosures. Made from brass, it offers inherent corrosion resistance and non-magnetic properties, making it ideal for marine, electrical, and instrumentation applications where material compatibility is critical. The 3/32" hex drive allows for straightforward installation with standard tools, even in tight spaces, enhancing assembly efficiency and reducing maintenance downtime.
