S-92311A427 10-32 x 3/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for maximum engagement and vibration resistance in demanding applications.
• Excellent corrosion resistance thanks to 18-8 Stainless Steel construction, ensuring long-term reliability in harsh environments.
• Secure and tamper-resistant installation with a headless hex drive design that allows for flush mounting and prevents accidental loosening.
• Enhanced grip and minimal component damage from the cup point tip, which bites securely into the mating surface without excessive marring.
• Consistent performance and durability backed by a Rockwell B80 hardness, providing the ideal balance of strength and toughness.
• Broad industrial compatibility with a 10-32 UNF fine thread, a common size for precision assemblies requiring fine adjustment.
• Confident global sourcing with compliance to ASME B18.3, RoHS 3, and REACH, meeting stringent quality and environmental standards.

Professional Applications & Engineering Value

This 10-32 UNF set screw is engineered to solve critical challenges in precision assemblies where space is limited and vibration is a concern. The headless design and hex drive allow for installation in confined areas while providing a secure, flush finish. Manufactured from 18-8 Stainless Steel, it resists corrosion in humid or chemically aggressive settings, extending the service life of machinery and equipment. The cup point creates a strong mechanical lock on shafts, collars, and gears, preventing slippage under high torque. Its Class 3A thread fit ensures precise engagement, reducing the risk of cross-threading and assembly errors in automated or manual production lines, making it a reliable choice for aerospace, automotive, and industrial automation applications.

Specification Summary & Compliance

This set screw features a 10-32 UNF fine thread with a Class 3A thread fit for high precision and a thread diameter of 0.19". It is manufactured in compliance with ASME B18.3 standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free of hazardous substances and suitable for global industrial use.
