Key Features & Benefits at a Glance
- Superior holding power with Class 3A thread fit ensuring precise, vibration-resistant connections in demanding applications
- Enhanced corrosion resistance from black-oxide alloy steel construction, extending service life in harsh industrial environments
- Maximum grip and alignment with 90° cone point design that bites into surfaces securely without slipping
- High strength and durability from Rockwell C45 hardness, maintaining structural integrity under heavy loads
- Easy installation in confined spaces with headless design and 1/16" hex drive for efficient tool access
- Reliable coarse thread performance using UNC thread type for quick assembly and strong engagement in various materials
- Comprehensive compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for quality and environmental safety
Professional Applications & Engineering Value
This 5-40 UNC set screw delivers exceptional engineering value through its black-oxide alloy steel construction and cone point design, specifically engineered to solve critical industrial fastening challenges. The 90° cone point creates concentrated pressure points that prevent component slippage in shaft collars, gears, and pulleys, while the Class 3A thread fit maintains precise alignment in high-vibration machinery. The headless configuration with 1/16" hex drive enables installation in space-constrained applications where traditional fasteners cannot operate. Black-oxide surface treatment provides an additional layer of protection against corrosion in manufacturing environments, making these set screws ideal for automotive assemblies, industrial equipment maintenance, and precision mechanical systems requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
This set screw maintains Class 3A thread fit precision with UNC coarse thread spacing and 5-40 thread size (0.125" diameter). Manufacturing complies with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The 3/16" length and right-hand thread direction ensure compatibility with standard industrial components and installation practices.
