Key Features & Benefits at a Glance
- Superior holding power with Rockwell C45 hardness alloy steel construction for maximum load-bearing capacity
- Enhanced vibration resistance through the cup point design that bites into mating surfaces securely
- Easy installation and removal with external square drive that prevents cam-out during high-torque applications
- Reliable thread engagement with 3/8"-16 UNC coarse threads and Class 2A fit for consistent performance
- Industrial compliance assurance meeting ASME B18.6.2 specifications for dimensional accuracy
- Environmental regulation compliance with RoHS 3 and REACH standards for safe industrial use
- Optimized for heavy-duty applications with 2" length providing deep penetration in demanding assemblies
Professional Applications & Engineering Value
This alloy steel set screw delivers exceptional engineering value in industrial applications where vibration resistance and permanent positioning are critical. The cup point configuration creates concentrated contact pressure that digs into shaft surfaces, preventing rotational slippage in power transmission systems, machinery components, and precision equipment. The 3/8"-16 UNC coarse threads with Class 2A fit ensure rapid installation while maintaining precise tolerances in high-volume production environments. With Rockwell C45 hardness and external square drive, this fastener withstands repeated torque applications without stripping, making it ideal for permanent fastening solutions in manufacturing, automotive, and heavy equipment industries where reliability cannot be compromised.
Specification Summary & Compliance
This set screw maintains Class 2A thread fit per UNC standards with precise dimensional control per ASME B18.6.2 specifications. The 3/8"-16 coarse thread configuration ensures proper engagement while the 2" length provides optimal clamping depth. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted substances for industrial applications requiring certified components.
