The JCP Fixings Metalfix Loose Washer is an essential hardware component for professional contractors and DIY enthusiasts who require secure, weather-resistant fastening for cladding installations. These 19mm washers are engineered to pair seamlessly with JCP cladding screws, providing a robust surface area to distribute pressure and ensure a long-lasting, durable connection. While they offer excellent protection against environmental degradation, users should note they are specifically sized for 19mm applications and are not universal for all bolt types.

These 19mm washers are specifically designed for JCP cladding screws. Please verify the specific screw diameter requirements for your project.
Yes, their zinc plating makes them suitable for both indoor and outdoor use, providing excellent rust resistance in most conditions.
The 19mm measurement refers to the outer diameter of the washer, which is optimized for load distribution on cladding sheets.
The Metalfix washer is a solid washer. If you require a watertight seal for roofing, you should ensure the screw system used includes an EPDM seal.
While zinc plating offers good corrosion resistance, for extreme coastal environments, stainless steel alternatives are typically recommended.
The fastener has not been tightened sufficiently; ensure the screw is seated flush against the washer and the substrate.
Check if the zinc plating was damaged during installation. If chipped, apply a touch-up of cold-galvanizing spray to prevent further spread.
Installation is straightforward: slide the washer onto the shank of your JCP cladding screw before driving the screw into the substrate. Ensure the surface is clean before application to maximize the seal. These washers are designed specifically for the JCP product line; while they may fit other standard screws, compatibility with non-JCP fasteners is not guaranteed. To maintain the life of the zinc plating, avoid overtightening with high-impact drivers which could chip the protective layer, and store in a dry environment to prevent premature oxidation.
