S-92695A155 8-32 x 1/2" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power thanks to the 90° cone point design that bites into mating surfaces for secure, vibration-resistant fastening
• Exceptional durability and corrosion resistance provided by the Black-Oxide finish on the alloy steel, extending service life in demanding environments
• High-strength performance ensured by a Rockwell C45 hardness, offering reliable resistance to wear and deformation under load
• Precise and secure thread engagement with Class 3A fit UNC coarse threads, enabling easier assembly and reduced risk of cross-threading
• Space-saving headless design allows for flush mounting in applications where clearance is limited
• Easy installation with standard tools using the 5/64" hex drive, facilitating quick and efficient assembly in tight spaces
• Compliance with major industry standards including ASME B18.3, ensuring consistent quality and interoperability in professional settings

Professional Applications & Engineering Value

This 8-32 UNC set screw is engineered to address critical challenges in industrial assembly, such as component slippage and loosening under dynamic loads. The Black-Oxide Alloy Steel construction, combined with a Rockwell C45 hardness, provides a robust solution that withstands high-stress conditions without compromising integrity. Its 90° cone point concentrates force to create a permanent, non-slip grip on shafts, collars, and pulleys, making it ideal for precision machinery, automotive systems, and conveyor equipment. The headless design and hex drive allow for discreet, tool-accessible installation in confined spaces, while the coarse UNC threads ensure rapid engagement and reduced assembly time. By meeting ASME B18.3 specifications, this fastener delivers consistent performance, minimizing downtime and maintenance costs in high-volume production environments.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a Class 3A thread fit for tight tolerances and reliable engagement in UNC coarse threading. It conforms to the ASME B18.3 manufacturing specification, ensuring uniformity and compatibility with industry-accepted components. Additionally, the product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for hazardous substance restrictions.
