S-92313A146 6-32 x 3/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and extended service life.
• Maximum holding power and vibration resistance provided by the cup point design, which bites into the shaft for a secure, non-slip lock.
• Precise and reliable thread engagement ensured by the Class 3A thread fit, minimizing the risk of cross-threading and ensuring consistent clamping force.
• High-strength performance with a Rockwell B80 hardness, offering excellent durability and resistance to wear under load.
• Easy installation in confined spaces thanks to the headless design and compact 1/16" hex drive.
• Broad industry compatibility with the standard 6-32 UNC coarse thread, facilitating easy replacement and assembly.
• Compliance with major industry and environmental regulations including ASME B18.3, RoHS 3, and REACH, ensuring safety and material reliability.

Professional Applications & Engineering Value

This 6-32 UNC set screw is engineered to solve critical challenges in precision assembly and motion control systems. Its 316 Stainless Steel material offers exceptional resistance to chemicals and saltwater corrosion, making it a top choice for marine, chemical processing, and food-grade equipment. The headless design and hex drive allow for flush mounting in tight spaces, while the cup point creates a permanent indentation on the shaft, providing superior resistance to loosening from vibrations—a common failure point in machinery and rotating components. Manufactured to ASME B18.3 specifications, this screw delivers consistent performance in demanding applications such as securing collars, gears, and pulleys onto shafts, ensuring operational reliability and reducing maintenance downtime.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, featuring a Class 3A thread fit for high-accuracy assemblies and UNC coarse threads for rapid installation. It is manufactured in compliance with the ASME B18.3 standard, ensuring consistent quality and interchangeability. The product is also verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming the use of safe, regulated materials free from hazardous substances, suitable for global industrial and commercial use.
