Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit ensuring tight, secure fastening in demanding applications
- Enhanced corrosion resistance from black-oxide coating, extending service life in harsh industrial environments
- High-strength durability due to alloy steel construction with Rockwell C45 hardness, resisting deformation under heavy loads
- Easy installation and removal with hex drive design, allowing for efficient assembly and maintenance
- Reliable coarse UNC threading providing quick engagement and reduced cross-threading risks
- Space-saving headless design ideal for applications where protruding components are not feasible
- Compliance with major industry standards including ASME B18.3 and ASTM F912, ensuring consistent quality and performance
Professional Applications & Engineering Value
This 3/8"-16 UNC set screw delivers exceptional engineering value in industrial settings where vibration resistance and permanent positioning are critical. The black-oxide alloy steel construction combined with Rockwell C45 hardness prevents loosening under dynamic loads, making it ideal for machinery components, motor shafts, and precision equipment. The hex drive and coarse thread design enable quick installation in tight spaces while maintaining high clamp force. Its headless configuration is particularly valuable in rotating assemblies where clearance is limited, providing reliable fixation without interference. These features address common industrial challenges like component slippage, corrosion-induced failure, and maintenance downtime.
Specification Summary & Compliance
This set screw features precision 3/8"-16 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy. Manufactured to ASME B18.3 specifications and ASTM F912 standards, it ensures consistent performance in industrial applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances above threshold limits.
