S-91375A928 3/8"-16 x 1" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit for precise, secure fastening in demanding applications.
• Excellent corrosion resistance provided by the zinc plating, extending the screw's service life in various environments.
• High-strength durability from the alloy steel construction and Rockwell C45 hardness, resisting wear and deformation.
• Secure, non-slip installation enabled by the hex drive, allowing for high torque application without cam-out.
• Effective component positioning with the cup point tip design, which bites into surfaces to prevent movement.
• Reliable coarse threading (UNC) for faster installation and reduced cross-threading risk in industrial assemblies.
• Compliance with major industry standards including ASME B18.3, ensuring quality and interoperability.

Professional Applications & Engineering Value

This zinc plated alloy steel set screw is engineered to solve critical challenges in industrial assembly and machinery. The headless design and cup point tip provide a flush finish and positive locking, preventing axial movement of components on shafts, collars, and gears. Its Class 3A UNC coarse thread ensures a tight, precise fit, reducing the risk of vibration-induced loosening in high-stress environments. The hex drive accommodates standard tools for efficient installation and removal, making it a reliable choice for maintenance and production lines where durability and secure fastening are paramount.
