Fixing Chipboard

Self-drilling chipboard screws have a coarse thread and fine shank to provide maximum grip and minimum strip out into chipboard, MDF board or soft timbers. The head has ribs molded around the countersunk head which help remove the chipboard particles when countersinking.

How to Use

  1. Measure the total thickness of the materials to be fastened.
  2. Choose a screw long enough to provide approx. 20mm of thread embedment into the chipboard or wood being fastened to.
  3. Fit a #2 Phillips drive bit to a power screwdriver set to low speed, approx. 1000rpm.
  4. Put screw onto drive bit and place at fastening position.
  5. Push sharply on screwdriver to create a starting point.
  6. Drive screw home until the head flushes with surface.
  • Note: Coloured furniture caps are available for that perfect finish.

Fixing Polycarbonate Roofing

Self-drilling screws and sealing washers are designed for fixing polycarbonate, fiberglass, PVC and fiber cement sheeting to both timber and metal.

How To Use

  1. For roofing, drill a 10mm hole and fix accordingly to roof sheet manufacturers specifications.
  2. Insert the PolyTeks screw and ensure the washer is over the hole. Drive screw home with a 5/16" Hex socket fitted to a power screwdriver.
  3. Be careful not to overtighten.
  4. To calculate the number of fasteners/washers required, multiply the square meter of the roof by five.
