S-92845A146 6-32 x 3/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and extended service life.
• Exceptional holding power ensured by the Class 3A thread fit, providing a tighter, more secure fastening with minimal backlash.
• Reliable, non-slip installation using the compact 1/16" hex drive, perfect for confined spaces and high-torque applications.
• Enhanced grip and component security from the extended tip design, which bites into the mating surface to prevent loosening under vibration.
• High mechanical strength and durability with a Rockwell B80 hardness, resisting wear and deformation in demanding industrial use.
• Broad compatibility and easy sourcing thanks to the standardized 6-32 UNC coarse thread and right-hand direction.
• Confidence in regulatory compliance as it meets ASME B18.3 specifications and is RoHS 3 and REACH compliant.

Professional Applications & Engineering Value

This 6-32 UNC set screw is engineered to solve critical challenges in industrial assembly and precision machinery. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for applications exposed to moisture, chemicals, or outdoor elements. The headless design and 1/16" hex drive allow for flush mounting and secure fastening in tight spaces where traditional screw heads are impractical. The extended tip concentrates pressure on a small area, creating a permanent seat that prevents shaft or collar slippage under high vibrational loads. Its Class 3A thread fit and coarse thread spacing ensure rapid assembly and a reliable, high-strength connection, reducing the risk of joint failure in power transmission components, gears, and pulleys.

Specification Summary & Compliance

This set screw features a 6-32 UNC thread with a Class 3A fit for precision tolerance, a length of 3/8", and a tip diameter of 0.092". It is manufactured in compliance with the ASME B18.3 standard and is confirmed to be RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring it meets stringent environmental and safety regulations for industrial use.
