Knurled Brass Insert Screw Cups
Solid brass screw cups designed to provide a highly professional and flush decorative finish when used with countersunk screws.

Manufactured from solid brass, these insert screw cups are commonly used in furniture making, cabinetry, decorative panels and joinery where a premium appearance is required. They allow the screw head to sit neatly within the cup, creating a clean and refined finish while protecting the surrounding timber surface.

Brass screw cups are particularly suitable for panels that may require periodic removal and refitting, as they help maintain a consistent and tidy appearance around the fixing.

Installation Guidance
For best results:

  1. Drill a pilot hole using the recommended drill hole diameter provided in the product specification.
  2. Please note: the drill hole size is provided as a guide only and may vary depending on timber hardness. Harder woods may require slight adjustment.
  3. Cover the brass cup before gently tapping it into place to prevent marking or damage to both the brass and the timber surface.
  4. Insert the matching countersunk screw and tighten securely.

Correct installation ensures the cup sits flush and maintains a clean decorative finish.
