Plastic Washer Ø5 mm for Screws (Canvas Grommet Spacer)

The Ø5 mm plastic washer is a small yet important accessory for installing boat covers and hardware. It spreads the load of a screw head over a larger area, protecting fabric or surfaces from chafing and tear-out. Made of durable plastic, this washer will not corrode and fits screws with ~5 mm shank diameter (e.g. 4.8–5.5 mm). Available in white and black.

Size: 5 mm inner diameter (fits standard #8–#10 screws); outer diameter ~12 mm to effectively distribute pressure
Material: Tough UV-resistant plastic – withstands outdoor conditions without cracking or degrading
Purpose: Acts as a spacer and reinforcing washer when fastening canvas, tarpaulins, covers, etc., with screws
Usage: Place under the screw head (especially with countersunk/flat heads) to ensure even clamping and prevent direct metal-to-fabric contact
Advantage: Lightweight, non-metallic washer – no rust or metal reaction; maintains a clean look and increases the strength of the assembly

This Ø5 mm plastic washer is designed to serve as a backing pad when driving screws through fabric or other materials on your boat. When attaching a cover, canopy, or accessory with a screw, adding this washer under the screw head greatly improves the strength and longevity of the fastening. The washer distributes the force evenly exerted by the screw over a broader area – preventing the concentrated pressure that could tear or deform the canvas/material around the screw. Additionally, the plastic washer acts as a buffer between the metal screw and the fabric, reducing chafe and abrasion under vibration.

Made from high-quality plastic, the washer won’t absorb water and will not rust. Unlike metal washers, there’s no risk of corrosion or staining. The 5 mm hole size easily slips over standard screws with roughly 5 mm thread diameter. It is suited for flat-head screws (especially countersunk heads), featuring a flat, wide shape – ideal for screws used to secure snap fasteners, canvas eyelets, brackets, etc. to the hull or frame.

Application: For example, when installing a snap button with a screw, you would first slide a plastic washer onto the screw before driving it through the fabric into the base. The washer will sit between the screw head and the canvas, protecting the cloth. Similarly, if you are fastening a tarpaulin or cover directly with screws onto a wooden or fiberglass surface, placing a washer under each screw head will reinforce the hole and prevent tear-out around it under tension.

We offer these washers in two colors – white and black – to suit different uses. White washers are nearly invisible against light-colored canvases or white structures, while black ones are preferred for dark covers or black frames. They are lightweight and easy to use, yet significantly enhance the reliability of your installation. Adding a plastic washer is a small step that protects your gear and textiles from damage, ensuring your covers and their attachment points last longer.
