FAQs

Q1: Does the MS countersunk head screw sit flush and burr-free?

A: Yes. The Fong Prean Magic Spiral countersunk head screw is engineered to deliver a perfectly flush finish without burrs, ensuring a clean, professional appearance on wood, MDF, PVC, and other materials.


Q2: Which materials can the MS countersunk head (CSK) screw be used with?

  • Hardwoods: IPE, maple, merbau (Kwila), oak
  • Engineered wood panels: MDF, melamine board, plywood
  • Boards: Hard gypsum board; fiber-cement boards such as Hydropanel, cement board
  • Others: PVC and rubber

Q3: What’s the difference between Magic Spiral, 24-Ribs MS, and MS Trim countersunk head screws?

  1. Magic Spiral (MS) Head | All-purpose, clean flush
    Patented MS countersunk head screw delivers a flush, burr-free countersink on a variety of materials (wood, MDF, melamine, PVC, rubber, hard gypsum board, Hydropanel). Ideal when you need a neat finish without extra work.
  2. 24-Ribs MS Head | For dense, hard boards
    24 ribs help the CSK screw self-countersink faster and prevent burrs or mushrooming in hardwoods and tough boards—perfect for decking, outdoor applications, and fiber-cement boards.
  3. MS Trim Head | Low-profile, discreet look
    Smaller trim countersunk head screw for a concealed appearance while still delivering burr-free results—great for ceiling, decking and other visible interior work.
