S-95289A131 10-32 x 1/2" 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 long-term reliability.
• Maximum holding power and vibration resistance achieved through the Class 3A thread fit, ensuring a secure and precise fastening.
• Enhanced grip and component positioning from the extended tip design, preventing loosening under dynamic loads.
• High-strength durability with a Rockwell B80 hardness, providing excellent resistance to wear and deformation.
• Easy and secure installation using a standard 3/32" hex key, facilitated by the headless design for flush mounting in tight spaces.
• Reliable performance in fine-thread applications with the 10-32 UNF right-hand thread, offering superior tensile strength.
• Guaranteed industrial compliance meeting ASME B18.3 standards and environmental regulations like RoHS and REACH for safe, global use.

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 extended tip allow for flush mounting while biting into the shaft material to prevent rotational slip, making it ideal for securing pulleys, gears, and collars in machinery. Manufactured from 18-8 Stainless Steel, it offers excellent corrosion resistance, reducing maintenance needs in humid or chemical-exposed environments like marine equipment or food processing units. The Class 3A thread fit and fine UNF threads ensure a tight, reliable clamp force, essential for high-stress applications in automotive, aerospace, and industrial automation, where failure is not an option. This combination of material and design delivers long-term reliability and precise component alignment.
