Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Precise, secure fastening ensured by Class 3A thread fit, minimizing backlash and maintaining alignment in critical assemblies.
- High torque transmission and strip resistance from the hex drive and Rockwell B80 hardness, allowing for repeated adjustments without wear.
- Enhanced grip and component retention due to the extended tip design, which bites firmly into shafts and hubs.
- Easy installation in confined spaces with the headless and right-hand thread design, simplifying assembly and disassembly.
- Reliable performance in fine-thread applications with UNF 1/4"-28 threading, providing greater adjustment precision and vibration resistance.
- Compliance with industry standards including ASME B18.3, RoHS, and REACH, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This 1/4"-28 UNF Class 3A set screw is engineered to address common industrial challenges such as component slippage and corrosion-induced failure. Made from 18-8 stainless steel, it offers excellent resistance to rust and oxidation, making it suitable for applications in machinery, automotive, and outdoor equipment. The extended tip and fine thread spacing provide superior gripping force and precise positioning, reducing the need for frequent retightening in high-vibration environments. Its headless design with a hex drive allows for flush mounting and easy access in tight spaces, enhancing assembly efficiency. Ideal for securing collars, gears, and pulleys, this set screw delivers reliable performance where durability and precision are critical.
Specification Summary & Compliance
This set screw adheres to Class 3A thread fit tolerances for high precision, with UNF fine threads and a right-hand thread direction. It meets ASME B18.3 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial uses.
