Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
- Exceptional holding power provided by the 90° cone point design, which bites into materials to prevent component slippage.
- High-strength threading with UNC Class 3A fit ensures precise, secure fastening and reduced risk of cross-threading during installation.
- Easy installation and removal using a standard 1/8" hex key, thanks to the headless hex socket design that saves space and allows flush mounting.
- Reliable performance in high-vibration applications due to the coarse thread spacing and right-hand thread direction, maintaining clamp load.
- Consistent quality and interchangeability guaranteed by compliance with ASME B18.3 standards, ensuring fit with matching components.
- Safe for regulated industries with full RoHS 3 and REACH compliance, meeting environmental and health safety requirements.
Professional Applications & Engineering Value
This 1/4"-20 UNC Class 3A set screw is engineered to address common industrial challenges such as component loosening under dynamic loads and corrosion in demanding environments. The 18-8 Stainless Steel material offers excellent resistance to rust and oxidation, making it suitable for outdoor, marine, or chemical-exposed applications. Its headless design with a hex socket drive allows for compact assembly in tight spaces, while the 90° cone point provides aggressive gripping action on shafts, collars, and pulleys, preventing rotational slip. The coarse UNC threads ensure quick installation and robust performance in high-vibration settings like machinery, automotive systems, and conveyor equipment, delivering reliable, long-term fastening solutions.
Specification Summary & Compliance
This set screw features a 1/4"-20 UNC coarse thread with a Class 3A tolerance for high precision and strength. It is manufactured in accordance with ASME B18.3 specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met.
