Square Washer

A square washer is a flat, four-sided fastener designed with a central round hole. Its primary functions are to distribute the load of a bolt or nut over a larger area, provide a stable bearing surface on uneven materials, and effectively prevent rotation by locking against flat edges or structural elements.

Product details

Typical Applications:

Structural Steel & Construction: Used with square-headed bolts in steel frame connections, where the shape prevents rotation during assembly and provides a larger bearing surface on wood or steel.
Rail & Track Fastening: Commonly employed in rail systems to secure ties and plates, where the square profile helps resist loosening under vibration.
Electrical & Utility Mounting: Ideal for mounting equipment to channel struts or unistrut, as the washer sits securely within the channel to prevent turning.

Our Product & Custom Capabilities:
We supply square washers in various materials and finishes to meet specific application demands. Our customization options include:

Material & Strength: Standard carbon steel, high-strength alloy steel, or corrosion-resistant stainless steel (304/316).
Precise Dimensions: Custom inside/outside diameters, exact thickness, and controlled square size to fit specific bolt sizes and space constraints.
Surface Treatment: Zinc plating, hot-dip galvanizing, or black oxide coating to enhance durability and corrosion protection for indoor or outdoor use.

Our square washers offer a reliable solution for enhancing joint stability, improving load distribution, and ensuring long-term fastening integrity in demanding applications.
