S-92695A520 3/8"-24 x 3/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Class 3A thread fit for secure, vibration-resistant fastening in demanding applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in various industrial environments.
• High-strength durability backed by Rockwell C45 hardness, ensuring the set screw withstands high stress without deforming.
• Precise and secure installation with a 3/16" hex drive, allowing for high torque application and reducing the risk of stripping.
• Effective penetration and locking due to the cone point tip with a 118° angle, ideal for creating a permanent seating on shafts and components.
• Reliable performance in fine-thread applications with 3/8"-24 UNF threads, providing a tighter fit and improved load distribution.
• Compliance with major industry standards including ASME B18.3 and ASTM F912, ensuring consistent quality and interoperability.

Professional Applications & Engineering Value

This black-oxide alloy steel set screw is engineered to solve critical challenges in industrial assembly, such as component slippage and vibration-induced loosening. The headless design with a hex drive allows for flush mounting in confined spaces, while the cone point tip bites securely into materials, preventing rotational movement in shaft collars, gears, and pulleys. Made from high-strength alloy steel and treated with a corrosion-resistant black-oxide coating, it excels in automotive, machinery, and heavy equipment applications where durability and precision are paramount. The fine UNF threads and Class 3A fit ensure minimal backlash, providing reliable performance in high-vibration environments and reducing maintenance needs.

Specification Summary & Compliance
