Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh or outdoor environments.
- Exceptional holding power due to the Class 3A thread fit, ensuring a tight, secure, and vibration-resistant connection.
- Deep penetration and secure seating provided by the 90° cone point, which bites into the shaft for maximum resistance to loosening.
- High-strength durability with a Rockwell B80 hardness, offering reliable performance under heavy loads and stress.
- Easy installation and removal with a 3/16" hex drive, allowing for high torque application in confined, headless designs.
- Broad compatibility with the 3/8"-16 UNC coarse thread, making it a versatile choice for a wide range of industrial assemblies.
- Guaranteed reliability and safety through compliance with ASME B18.3 specifications and RoHS/REACH environmental standards.
Professional Applications & Engineering Value
This 3/8"-16 UNC Class 3A stainless steel set screw is engineered to solve critical challenges in power transmission and motion control systems. The headless design and hex drive allow for flush mounting in pulleys, gears, and collars, preventing interference in compact machinery. The 90° cone point and coarse thread work in tandem to create a deep, permanent indentation on shafts, effectively resisting rotational forces and vibration-induced loosening in high-torque applications. Made from 18-8 Stainless Steel, it provides excellent resistance to rust and corrosion, making it a dependable heavy-duty fastener for automotive, aerospace, and marine equipment where reliability is non-negotiable.
Specification Summary & Compliance
This set screw adheres to a Class 3A thread fit for superior precision and a tight grip. It conforms to the UNC (Unified National Coarse) thread standard and is manufactured in compliance with the ASME B18.3 specification. The product is also verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for industrial use.
