S-94105A617 3/8"-24 x 3/8" ASME B18.3, ASTM F912 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 3A thread fit ensuring precise, vibration-resistant fastening in demanding applications
• Enhanced corrosion resistance through black-oxide coating that protects against rust and extends service life in harsh environments
• Maximum torque transmission via hex drive design that prevents cam-out and allows for high tightening forces
• Exceptional strength and durability from alloy steel construction with Rockwell C45 hardness for reliable performance under heavy loads
• Precision alignment capability with flat tip design that provides secure positioning without damaging mating surfaces
• Industry-standard compatibility through UNF fine thread spacing (3/8"-24) that ensures perfect fit with standard components
• Space-saving installation thanks to headless design that allows for flush mounting in confined spaces

Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers exceptional engineering value in precision assembly applications where vibration resistance and reliable positioning are critical. The Class 3A thread fit provides superior tolerance control that prevents loosening in high-vibration environments such as industrial machinery, automotive systems, and precision equipment. The hex drive headless design enables flush installation while maximizing torque application, making it ideal for securing collars, gears, and pulleys on shafts where space constraints exist. The combination of UNF fine threading and Rockwell C45 hardness ensures the screw maintains its clamping force under dynamic loads, solving common challenges of component slippage and positional accuracy in mechanical assemblies.

Specification Summary & Compliance

This set screw features precision 3/8"-24 UNF Class 3A threads with fine thread spacing, manufactured to exacting dimensional standards. The component meets ASME B18.3 specifications (ASTM F912) for dimensional accuracy and performance requirements. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and workplace safety. The inch system measurement and right-hand thread direction provide compatibility with standard industrial components, while the flat tip design and 3/8" length offer versatile application solutions across various engineering contexts.
