Fastcap 18mm Wood Washer is a wood washer with an 18mm head diameter designed to give screws extra holding power. The large 18mm head diameter spreads the load over more surface area, which supports a stronger connection in demanding fastening points in wood projects. A built-in recess lets the screw sit flush in the washer, so the head seats cleanly instead of riding proud, helping parts draw together tightly. The washer is part of Fastcap screw cover caps and washers, so it fits into fastening layouts where appearance and holding strength both matter. When more pull-down strength is needed from a standard screw, this washer helps the screw do more work without changing drilling steps or basic layout.
The Fastcap wood washer works with #6 and #8 v. flat or countersunk screws, so it drops directly into many existing screw schedules using those sizes. Because it turns any tapered screw into a PowerHead Screw, the washer lets that tapered screw behave like a large-head fastener, which can improve pull-down at joints or brackets. The recess that allows the screw to sit flush keeps the head neatly contained, which helps alignment when driving screws close to edges or hardware. With an 18mm head diameter, layout around adjacent hardware, edge distances, and spacing can be planned knowing the washer footprint stays consistent.
This Fastcap 18mm wood washer is part of the screw cover caps and washers category, so it is suited to woodworking and cabinet applications where screws both hold and remain visible. The 18mm head diameter gives a predictable bearing surface, which helps across face frames, cleats, and brackets needing enhanced grip. Working with #6 and #8 v. flat or countersunk screws lets it serve in many assembly points that already rely on those sizes, reducing the need for alternate fastener diameters. When extra holding power is needed, the washer adds that support around the screw head, which is useful at joints under load or where repeated opening and closing puts stress on the fastener point. Because it can later be hidden with a Fastcap, it supports projects where strong mechanical fastening and a clean finished surface are both priorities.
The recess that allows your screw to sit flush in the washer shapes how the screw engages the wood, which promotes consistent seating depth across multiple fasteners. By turning any tapered screw into a PowerHead Screw, the washer effectively enlarges the head contact area, which helps reduce head pull-through in wood or man-made panels. Compatibility with #6 and #8 v. flat or countersunk screws gives clear boundaries for planning pilot holes and driving torque, which supports uniform results across an installation. The 18mm head diameter remains constant from fastener to fastener, which aids in laying out symmetrical rows or pairs of washers around hardware such as brackets or rails. As a Fastcap product in the screw cover caps and washers class, it aligns with Fastcap cover solutions, which can simplify achieving a consistent look across multiple fastening locations once structural fastening is complete.
