S-92695A732 6-40 x 1/4" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide coating, extending service life in demanding industrial environments.
• Precise, reliable fastening ensured by Class 3A thread fit for minimal backlash and secure component positioning.
• High-strength durability from alloy steel and Rockwell C45 hardness, resisting wear and deformation under load.
• Secure, flush installation with headless design and 90° cone point, ideal for permanent assemblies and limited-clearance applications.
• Efficient installation and removal using the 1/16" hex drive, providing excellent torque transfer in confined spaces.
• Optimized for fine-adjustment applications with 6-40 UNF fine threads, offering greater thread engagement and vibration resistance.
• Guaranteed quality and safety compliance meeting ASME B18.3, RoHS 3, and REACH standards for reliable, eco-conscious procurement.

Professional Applications & Engineering Value

This black-oxide alloy steel set screw is engineered to address critical challenges in precision assembly and machinery. Its headless design and 90° cone point provide a secure, low-profile fastening solution that minimizes protrusion and prevents component slippage in shafts, collars, and gears. The 6-40 UNF fine thread with Class 3A fit ensures tight tolerances and superior holding power, reducing the risk of loosening under vibration—common in motors, actuators, and automation equipment. Made from hardened alloy steel (Rockwell C45), it delivers exceptional shear strength and durability, making it suitable for high-stress industrial applications where reliability and long-term performance are paramount.

Specification Summary & Compliance

This set screw features a 6-40 UNF thread with Class 3A fit (tight tolerance for external threads), fine thread spacing, and a right-hand thread direction. It is manufactured in accordance with ASME B18.3 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use across global industrial supply chains.
