Product Description
Product Overview
This product is a square slant notched washer complying with the GB853 standard, specially designed for channel steel structures. Manufactured from Q235 carbon steel, it achieves Grade A precision. Its unique square design with a single-side slant notch can be effectively embedded or clamped into the edge of channel steel, preventing the washer from rotating synchronously with the bolt/nut during tightening. The surface is treated with galvanization (rainbow passivation), which has both basic rust prevention function and certain decorativeness. It is suitable for the connection and fixation of channel steel and other profiles, and can improve assembly efficiency and connection reliability.
Core Advantages
-
Professional Anti-Rotation Design: The square slant notch structure is specially designed to fit the edge of channel steel. It can be clamped into the groove during installation, effectively preventing the washer from rotating and ensuring stable preload.
-
Optimized for Channel Steel Connection: Specially designed for bolt connection of channel steel and other profiles, it can better disperse pressure, compensate for uneven contact surfaces, and improve connection reliability.
-
Basic Rust Prevention and Identification: The galvanized layer (rainbow color) provides basic rust prevention protection, and the bright color also facilitates identification and distinction during installation.
-
Convenient Installation: The slant notch design facilitates quick positioning and alignment with the edge of channel steel, simplifying the installation process and improving assembly efficiency.

Warm Tips
-
Before installation, please confirm whether the edge of the channel steel is flat to ensure that the square slant notch of the washer can be effectively clamped to achieve the anti-rotation function.
-
The rust prevention ability of the rainbow galvanized layer is better than that of ordinary oxidation treatment, but its rust prevention ability is still limited when it is in a high-humidity or corrosive outdoor environment for a long time.
-
It is recommended to use it with bolts and nuts with the same rust prevention treatment to maintain the rust prevention consistency of the connection system, and check and maintain it regularly.
