Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
- Enhanced weld integrity due to the low-profile rectangular barrel design, providing a stable and flush mounting surface.
- Precise thread engagement with Class 6H fit, reducing the risk of cross-threading and ensuring secure fastening.
- Optimized for 5.6mm mounting holes, facilitating quick and accurate installation in welding applications.
- Compact, space-saving profile with a 0.8mm barrel height, ideal for applications with limited clearance.
- Durable coarse thread (M4 x 0.7mm) that resists loosening under vibration and allows for faster assembly.
- Compliance with environmental standards including REACH and RoHS 3, ensuring safe and sustainable use.
Professional Applications & Engineering Value
This M4 rectangular weld nut is engineered to address common challenges in industrial welding, such as space constraints and the need for reliable, corrosion-resistant fasteners. The low-profile barrel design (5.2mm diameter, 0.8mm height) minimizes protrusion, making it ideal for tight spaces in machinery, automotive frames, and electrical enclosures. Constructed from 18-8 stainless steel, it offers excellent resistance to rust and oxidation, extending service life in demanding environments. The Class 6H thread fit ensures consistent performance, reducing assembly errors and maintenance needs. Its rectangular base (15.9mm length, 9.6mm width) provides a larger welding area, enhancing joint strength and stability in high-stress applications.
Specification Summary & Compliance
This metric weld nut features precise dimensions: barrel diameter of 5.2mm, barrel height of 0.8mm, base length of 15.9mm, base width of 9.6mm, and base thickness of 2.4mm. It is designed for a 5.6mm hole diameter and includes a right-hand M4 x 0.7mm coarse thread with Class 6H thread fit per metric standards. The product complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU), ensuring adherence to environmental and safety regulations for industrial use.
