Securpak Chrome Plated (CP) Cup Washers No.8 – Pack of 16

For a Tidy, Decorative, and Flush Screw Finish in Wood and Metal Applications

Product Overview

The Securpak CP Cup Washers No.8 – Pack of 16 is a practical and decorative solution designed to enhance the appearance and performance of countersunk screw fixings. Commonly used in carpentry, cabinetry, and general hardware installation, these cup washers are specifically made to accommodate No.8 countersunk head screws, allowing them to sit flush while delivering a clean, polished finish.

Manufactured from durable metal and chrome-plated for corrosion resistance, each cup washer is shaped to cradle the head of the screw, spreading the load more evenly and protecting the surface material from damage. This not only improves strength and durability but also adds a neat, professional appearance—ideal for visible screw installations in woodwork, electrical fittings, display units, or decorative fixtures.

Key Features and Benefits

Neat and Polished Finish

Designed to complement countersunk screws, each washer provides a smooth, recessed surface for the screw head to sit in—resulting in a clean, professional look on visible surfaces.

Chrome Plated for Durability

The chrome finish not only enhances the washer's appearance but also protects against rust, corrosion, and tarnishing, making them suitable for indoor and occasional outdoor use.

Distributes Load Evenly

Helps to reduce pressure on the material beneath the screw head, minimizing the risk of damage, especially in softer materials such as timber or composite boards.

Improves Fixing Strength and Longevity

Cup washers help to prevent countersunk screws from pulling into or through the base material, which can lead to structural weakness over time.

Easy to Use

Simply position the washer between the countersunk screw head and the surface, then drive the screw into place for instant reinforcement and improved aesthetics.

Installation Instructions

Drill and Countersink the Hole (if required)
Ensure your screw hole is appropriately sized and, if needed, countersunk for a flush finish.

Place the Cup Washer
Position the washer on the surface, aligned with the screw hole.

Insert the Countersunk Screw
Drive the screw through the washer and into the base material until snug. The head should sit cleanly in the cup for a tidy appearance.

Avoid Over-Tightening
Tighten until secure but avoid excessive force to prevent distorting the washer or damaging the surface.

Care and Maintenance

Keep Dry When Possible: While chrome-plated, exposure to moisture over long periods may lead to tarnishing—especially in humid environments.

Wipe Clean: Maintain shine and remove dust with a soft, dry or lightly damp cloth.

Avoid Abrasives: Do not use metal scourers or harsh chemicals, which may scratch or dull the finish.
