S-92845A728 8-32 x 1" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
• Maximum holding power and vibration resistance due to the Class 3A thread fit, ensuring a tight, secure fastening in demanding applications.
• High-strength durability with a Rockwell B80 hardness, providing excellent resistance to wear and deformation under load.
• Easy and secure installation with the 5/64" hex drive and headless design, allowing for flush mounting and access in confined spaces.
• Enhanced gripping capability from the extended tip, which digs into the mating surface to prevent component slippage.
• Wide compatibility and reliable performance with UNC coarse threads and right-hand direction, conforming to common industrial standards.
• Global regulatory compliance meeting ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental standards are met for international supply chains.

Professional Applications & Engineering Value

These 8-32 UNC set screws are precision-engineered from 18-8 stainless steel to address critical challenges in industrial assembly, such as component loosening due to vibration and exposure to corrosive elements. The Class 3A thread fit and coarse thread spacing provide a robust, reliable hold in materials like steel and aluminum, reducing the need for frequent maintenance. The hex headless design with a 5/64" drive facilitates installation in tight spaces, while the extended tip ensures positive engagement, preventing axial movement in pulleys, gears, and collars. Ideal for machinery, automotive, and electronics, these screws deliver consistent performance and longevity, backed by compliance with ASME B18.3 and environmental regulations.
