Depth setting

Getting someone else to do a job for you can be costly. But with the right approach you can do a lot by yourself. You’ll save time and money by using the handy step-by-step instructions that you’ll find on the SKIL website. These step-by-step instructions are divided into categories relating to the different kinds of jobs in and around the home, and give you clear, A to Z explanations.

Just click on one of our step-by-step instructions and you’ll be able to get started right away!

  1. Depth setting

    Use your drill’s depth gauge to avoid drilling the hole too deep. If your drill doesn’t have a depth gauge you can slide a spacer ring on the drill bit and tighten the screw to fix it at the right drilling depth. If you don’t have a spacer ring, you can stick a piece of colored tape at the right place on the drill bit.

  2. The right combination of screw, plug and drill bit

    The right choice of screw and plug depends on the weight to be supported and the material of which the wall is made. The right combinations of screws, plugs and drill bits are shown below.

  3. Universal wall plugs

    These plugs are suitable for all kinds of surfaces, and are available in two types. If the plug has a collar at the open end, the collar fits over the outside of the drilled hole and prevents the plug from sinking deeper into the hole. A plug without a collar can be pushed deeper into the wall or behind a tile. Available in Ø 5 to 14 mm.

  4. Brass anchor plug

    A brass anchor plug is suitable for all kinds of materials with a high and regular density. Once it is inserted into the hole this plug cannot rotate, so it is suitable for use in boards. These plugs can be used with M6 and M8 bolts.

  5. Hammer fixing

    Hammer fixings enable you to work very quickly – you just hammer the plug together with the screw into the drilled hole and it’s immediately secured. These fixings are intended for use in non-structural assembly jobs, as well as for window frames with large material thicknesses.
    Available in Ø 5, 6 and 8 mm and lengths of up to 120 mm.

  6. Short panel plug

    These plugs are suitable for boards with a thickness of 6 mm and upwards.
    They have a short expanding section and are intended to be used with particle board screws.
    Available in Ø 8, 10 and 12 mm.

  7. Plasterboard plug

    This plug has a self-tapping outside thread and can be used directly with a special bit, without the need to first drill a hole. Suitable for use with particle board screws up to Ø 5 mm.

  8. Butterfly plug

    The butterfly plug has ‘wings’ which spread out when the screw is tightened, giving the plug a high load-bearing capacity. These plugs will not turn in the hole when the screw is tightened. Butterfly plugs can be used in plasterboard, fiberboard and similar soft materials.
    Available with M5 and M6 screw threads.

  9. Aerated concrete plug

    This is a special type of plug for cellular or aerated concrete. With these plugs you should first predrill the hole to a smaller diameter and then drive the plug into the hole with a hammer.
    Available in Ø 8, 10 and 14 mm.

  10. Chemical anchors

    Chemical anchors are used to fix threaded rods or anchor rods in concrete or masonry. They use a capsule of quick-setting adhesive resin into which the rod is bonded, giving them a high load-bearing capacity. They are suitable for use in concrete and brickwork, and available from M8 to M16.
    How it works
    1 Drill a straight hole slightly larger than the diameter of the capsule
    2 Blow the dust out of the hole, for example using a drinking straw
    3 Push the capsule into the hole
    4 Insert a threaded rod or anchor rod into the hole, breaking the capsule open as you do it
    5 Push the threaded rod or anchor rod as far as possible into the hole, align it and then allow the adhesive resin to harden. After hardening you can cut or saw the threaded rod to the desired length if necessary
