Product Description
Product Overview
This product is a square slant washer complying with the GB/T 852 standard, manufactured from carbon steel material. Its unique square slant design can convert the axial force of the screw into the clamping force on the flanges of profiles such as channel steel and I-beam. The thickened design and black oxide treatment ensure structural strength and rust resistance under heavy-load working conditions, effectively solving the problem of profile inclined surface connection.
Core Advantages
-
Slant Surface Adaptability: The precisely designed slant angle perfectly matches the slope of the profile flange.
-
Excellent Bearing Strength: The thickened structure provides higher bearing capacity and prevents deformation at the connection.
-
Reliable Anti-Looseness and Anti-Vibration: The square structure effectively prevents rotation after installation and maintains long-term preload.
-
Basic Rust Protection: Black oxide treatment provides a uniform oxide layer with basic rust resistance.
Applicable Industries
-
Steel Structure Construction Engineering: Profile connection of workshop steel structures, bridge supports and building curtain wall support systems.
-
Heavy Equipment Installation: Fixation of bases and frames of mining machinery, engineering equipment and large machine tools.
-
Logistics and Warehousing Systems: Steel structure installation and adjustment of heavy-duty shelves and automated stereoscopic warehouses.
-
Transportation Equipment: Frame connection of railway vehicle chassis, truck carriages and containers.
-
Power Tower Facilities: Internal structure connection of transmission towers, substation frames and wind power towers.
-
Mechanical Equipment Manufacturing: Heavy frame assembly of pressure machinery, agricultural machinery and printing equipment.
Warm Tips
-
Please ensure the washer is in the correct direction during installation, and the slant surface is fully attached to the profile flange.
-
It is recommended to regularly check the connection tightness, especially in dynamic load environments.
-
For heavy corrosion environments, it is recommended to adopt a higher-level anti-corrosion treatment to ensure long-term use.
