Key Features & Benefits at a Glance
- Exceptional holding power with Class 3A thread fit ensuring tight, reliable fastening in high-vibration environments
- Superior corrosion resistance from Black-Oxide Alloy Steel construction, extending service life in demanding conditions
- High durability with Rockwell C45 hardness maintaining structural integrity under heavy loads
- Secure component positioning through 90° cone point design that digs into mating surfaces
- Easy installation and removal with hex drive style providing positive torque application
- Space-saving headless design allowing flush mounting where clearance is limited
- Industry-standard compatibility with UNC coarse threads for broad application across equipment and machinery
Professional Applications & Engineering Value
This Black-Oxide Alloy Steel set screw delivers critical engineering solutions for industrial assembly challenges. The Class 3A thread fit provides superior clamping force retention in high-vibration applications such as motor mounts, gear assemblies, and rotating machinery components. The 90° cone point creates positive mechanical locking by embedding into shaft surfaces, preventing axial movement in pulley and collar applications. With Rockwell C45 hardness, this UNC threaded set screw maintains dimensional stability under repeated stress cycles, while the hex drive configuration enables precise torque control during installation. Ideal for precision manufacturing equipment, automotive assemblies, and heavy machinery where reliable positioning and vibration resistance are paramount.
Specification Summary & Compliance
Manufactured to exacting ASME B18.3 specifications with Class 3A thread fit ensuring precision dimensional accuracy. Features 3/8"-16 UNC coarse threads with right-hand direction and 1 3/4" length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting international standards for industrial fastener applications.
