Key Features & Benefits at a Glance
- Superior corrosion resistance with 304 Stainless Steel construction, ideal for harsh industrial environments and extended service life.
- Secure, flush-mount fastening provided by the headless and hex drive design, preventing snagging and allowing for a clean, finished appearance.
- Enhanced grip and reduced component damage from the ball tip, which distributes pressure evenly on the contact surface.
- Reliable and consistent threading ensured by the UNC coarse thread and Class 2A fit, promoting easier assembly and high vibration resistance.
- Durable performance under load thanks to a Rockwell C30 hardness rating, maintaining thread integrity and tip shape.
- Simplified installation and removal with a standard 3/16" hex drive, compatible with common tools for efficient maintenance.
- Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global supply chains.
Professional Applications & Engineering Value
This 304 Stainless Steel set screw is engineered to address critical challenges in industrial assembly, such as loosening under vibration and corrosion in demanding conditions. The headless design with a hex drive allows for a secure, low-profile connection in pulleys, gears, and collars where protruding fastener heads are not feasible. Its UNC coarse thread ensures rapid installation and provides excellent holding power, while the ball tip minimizes stress concentration on shafts and components, preventing marring and ensuring precise axial location. Made from corrosion-resistant 304 stainless steel and hardened to Rockwell C30, it delivers long-term reliability in machinery, automotive, and marine applications, making it a vital component for durable fastening solutions.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a 3/8"-16 UNC coarse thread with a Class 2A thread fit for consistent accuracy and assembly ease. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industrial markets.
