- Efficient air or fluid passage enabled by the vented feature with a 0.042" diameter, perfect for pneumatic or hydraulic systems.
- Easy installation in confined spaces using the 5/64" hex drive and headless design, allowing for flush mounting.
- Quick assembly with coarse UNC threads and right-hand direction, reducing installation time in production settings.
- Compliance with environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in global markets.
Professional Applications & Engineering Value
This 8-32 UNC set screw is engineered to address common industrial challenges such as component slippage and corrosion-induced failure. Crafted from 18-8 Stainless Steel, it provides excellent resistance to rust and chemicals, making it suitable for machinery, automotive, and marine applications where exposure to moisture is a concern. The hex headless and cup point design ensures a firm grip on shafts or collars, preventing rotational movement in high-vibration environments like motors and conveyor systems. The vented construction allows for pressure equalization or lubrication flow, enhancing performance in pneumatic assemblies. With a Class 3A thread fit and coarse thread spacing, it delivers reliable fastening in demanding settings, reducing maintenance needs and downtime for B2B clients seeking durable industrial set screws.
Specification Summary & Compliance
This set screw adheres to UNC thread standards with a Class 3A thread fit for precise dimensional accuracy, featuring a thread diameter of 0.164" and a length of 3/16". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for international industrial use.
