M20, 20mm Internal Thread, Drop In Anchor, Zinc - Masonry, Brick, Concrete Expansion Anchor.

Fixaball sells M20, zinc plated drop in, masonry anchors.

 Drop In Anchor

Expansion anchor for fixing materials to all types of masonry, concrete, brick and non-porous stone. An internally threaded socket anchor for use with bolts or threaded rod of any length. Full expansion can be guaranteed by using the correct shouldered setting punch. Suitable for use in solid concrete.

M20, zinc plated drop in, masonry anchor applications:

  • Light to heavy-duty into solid concrete.
  • Mechanical and electrical services
  • Suspension systems (ceilings)
  • Cable Trays
  • Signs
  • Hand rails

M20, zinc plated drop in, masonry anchor advantages:

  • Flush fitting with no protrusion when not in use
  • Shallow embedment, hence less chance of drilling into rebar, and faster drilling
  • Removal of fixture leaves anchor undisturbed
  • Setting tool stamp marks to indicate complete expansion
  • Visual expansion check with setting tool
  • Permanent anchorage point in solid concrete, brick or masonry
  • Can be used with all types of bolts, screws and studs

 

M20, zinc plated drop in, masonry anchor installation:

  1. Drill a hole in the concrete using a hammer drill and a carbide tipped masonry drill bit, matching the bit size with the outside diameter of the drop-in anchor being used. Make sure the hole depth exceeds the minimum embedment (around 5%)
  2. Drill the correct diameter hole and depth.
  3. Clear the hole of all debris with a brush and blow out pump.
  4. Push the anchor into the hole until it is flush with the surface of the concrete.
  5. Insert the relevant setting tool of the same diameter as the anchor until it makes contact with the cone. Use a hammer to drive the setting tool into the anchor – stop hammering when the expander shoulder rests against the anchor or when it is blocked (in hard concrete).
  6. Tighten to the recommended torque using a torque wrench.

     Bolt Length:

    When the drop-in anchor is set flush with the base material, the minimum bolt length required equals the internal thread length of the anchor, plus the thickness of the material to be fastened, plus the thickness of any washers to be used.

    If the anchor is set deeper into the concrete, adjust the length accordingly, by adding the additional depth to the minimum anchor length.

     

    Anchor Spacing:

    The forces on a Drop-In Anchor are transferred to the material in which it is installed. If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the holding power of the anchors. Minimum spacing between anchors and minimum edge distances for the concrete drop-in anchor are as follows:

    My item is shown as delivered but it hasn't been?

    What can I do if my item is shown as delivered, but it hasn’t been received?
    If you’re the recipient:

    Check whether the item was sent using a service that obtains a signature on delivery. If it was, do you recognise the name of the person who accepted the item? The name will be provided by the person who accepted the delivery and not always the person on the address label.
    If the item was sent to your home, ask anyone else living there if they accepted the delivery. Please also check if the item has been left with a neighbour, or in your designated Safeplace if you have one.
    If the item was sent to your work address, check with the post room and your colleagues to see if someone accepted the delivery.
    If you bought the item online, check the shipping address was correct.

    UPS - Packages over 2 kgs

    We use UPS as our preferred courier. Please make sure all details of the address are included as courier drivers will not fill in the gaps, leading to long delays or even loss

     

    Fixaball, International Orders.

    Offshore and International Shipping

    We use Royal Mail, Airmail, Tracked & Signed for international orders.  However, if the order exceeds the maximum weight (2kg) we will use UPS. Often, discounts can be offered on light weight/ high value goods if you email or call. Also, faster delivery can be arranged on your request.  The dispatch window for all of our offshore sales is 1 working day (most likely same day dispatch if ordered before 2pm).

    Our delivery services are reliable; however, occasionally there may be a delay due to various unforeseen circumstances (weather, industrial action, holiday seasons). With this in mind, please consider feedback based on what we can control, which is our quick, dispatch time (same day if ordered before 2pm). Our aim is to do everything we can to support you.
