Important Loose Bolt Anchor Performance Dimensions

Thread Diameter of Hex Bolt Shield Hole Size Max Fix.Thickness
M8 14mm 10mm
M8 14mm 25mm
M8 14mm 40mm

 

NOTE: the 1st dimension refers to the thread diameter and not the hole diameter. Please see the table below for further information on what masonry drill bit to use. The 2nd dimension refers to the maximum fixture thickness (space between the underside of the head and the shield +/- 5mm). The 3rd dimension is the actual length of the hex-bolt/ hex-set that goes into the sheild (in brackets).

Installation of Shield Anchors

When drilling holes you must respect the specified minimum depth and diameters shown in the table below. Holes must be square to the surface of the base material (e.g concrete) for safety during installation and to optimise holding capacity. Use the material/ fixture as a template to dill accurate locations

If drilling through concrete that has rebar reinforcements, special care must be taken to avoid damaging them. If some rebar is encountered, abort the hole, repair with high quality mortar and create a new hole, no less than twice the diameter of the shield anchor, away.

Optimising your fixings holding capacity.

  • Clean the hole using an appropriate sized brush
  • Installation Temp is 0°: make sure water does not seep into the hole. The expansion water to ice could crack the concrete. Under wet conditions, use a specified injection resin.
  • Introduce the anchor through the material to be fixed into the hole up to the embedment depth, according to the values on the table. Use a hammer to ensure the required depth. Do not apply any intermediate layer between the material to be fixed and the washer, such as sealing products.
  • Apply the specified torque with a torque wrench.
  • In the case the holes on the material to be fixed have a bigger diameter than required, it is necessary to insert a thicker washer and of a bigger diameter. But please, note that this procedure does not ensure a correct distribution of shear loads amongst all the anchors of a same group, and this shear load is applied only to the anchors with a correct diameter on the material to be fixed.
