S-92313A535 1/4"-20 x 3/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure
• Superior holding power and vibration resistance due to the Class 3A thread fit and UNC coarse threading
• High-strength durability with a Rockwell B80 hardness, ensuring long-term reliability under load
• Secure, flush installation with a headless design and 1/8" hex drive for tamper-resistant fastening
• Effective grip and component positioning provided by the cup point tip, preventing loosening
• Guaranteed dimensional precision and interchangeability, manufactured to meet ASME B18.3 specifications
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental standards

Professional Applications & Engineering Value

This 316 Stainless Steel Set Screw is engineered to address critical challenges in industrial assembly, where corrosion, vibration, and precise component alignment are major concerns. The headless design and 1/8" hex drive allow for a flush finish, making it perfect for machinery, automotive, and marine applications where protruding fasteners are not feasible. The UNC coarse thread and Class 3A fit ensure a tight, secure connection that resists loosening under dynamic loads, while the cup point bites into the mating surface for enhanced grip. Its corrosion-resistant properties make it suitable for outdoor, chemical processing, and high-moisture environments, providing long-term performance and reducing maintenance needs.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a 1/4"-20 UNC thread with Class 3A fit for tight tolerances and a length of 3/8". It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental safety and material integrity.
