Washer Head Screw

A Washer Head Screw is a specialized fastener that combines a screw with a permanently attached, integral washer under the head. This design provides a pre-assembled solution that offers a consistently wide bearing surface, improving load distribution and often creating a sealing effect, while speeding up the assembly process.

Product details

Typical Applications:

Sheet Metal & Cladding: Widely used in attaching metal roofing, siding, or HVAC ducts, where the large washer head helps prevent pull-through and seals the pre-drilled hole against weather elements.
Plastic & Composite Assembly: Ideal for fastening plastic components, as the broad head distributes clamping force to reduce stress cracking and creep around the fastener hole.
Wood-to-Metal/Plastic Fastening: Commonly employed in furniture, decking, and signage to securely join materials of different densities while providing a clean, finished appearance and protecting the surface.

Our Product & Custom Capabilities:
We supply Washer Head Screws in a variety of drive types and thread forms. Our customization focuses on providing optimal performance for your specific material and application:

Head & Washer Design: Options for standard or fender washers, with choices in overall head diameter and profile (flat or slightly conical) to meet sealing or aesthetic requirements.
Material & Coating: Available in steel with various platinps (zinc, trivalent chrome) or in stainless steel (A2/A4). Special coatings like polyester paint can be matched for color and enhanced weatherability.
Thread & Point Type: Custom threads (including self-tapping, self-drilling, or machine screw threads) and point styles (drill point, sharp point) to suit the base material.

Our Washer Head Screws deliver a reliable, efficient fastening solution that combines the functions of a screw and a washer, ensuring a secure, durable, and often weather-resistant connection.
