- Excellent corrosion protection from the Black-Oxide coating on 18-8 stainless steel, ideal for harsh industrial environments
- Enhanced load distribution thanks to the 0.784" flange diameter, reducing surface pressure and minimizing damage to connected materials
- High-temperature durability with a nylon insert rated up to 250°F, ensuring reliable performance in demanding applications
- Easy installation and removal using standard external hex drive tools, saving time and labor costs
- Precise thread engagement with Class 2B UNC coarse threads for consistent fit and reduced risk of cross-threading
- Compliance with environmental standards, meeting REACH and RoHS 3 requirements for safe, sustainable use
Professional Applications & Engineering Value
This nylon insert locking flange nut is engineered to address common challenges in industrial assemblies, such as vibration-induced loosening and corrosion in demanding settings. The Black-Oxide 18-8 stainless steel construction provides robust resistance to rust and chemicals, extending service life in applications like machinery, automotive systems, and outdoor structures. The flange design eliminates the need for separate washers, distributing clamp load evenly to prevent material deformation and maintain joint integrity. With a UNC coarse thread and Class 2B fit, it ensures quick, reliable installation while the nylon insert delivers consistent locking force up to 250°F, making it ideal for heavy-duty fastening in construction, transportation, and manufacturing sectors where reliability is critical.
Specification Summary & Compliance
This flange nut features a 3/8"-16 UNC coarse thread with Class 2B tolerance for precise fit and ease of assembly. It complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) standards, ensuring environmental safety. The nut is made from 18-8 stainless steel with a Black-Oxide finish and includes a right-hand thread direction, flange diameter of 0.784", and height of 27/64" for consistent performance in industrial applications.
