Wall fixing plugs are designed and manufactured in the UK. The fixing plugs are designed to expand in two directions. This two way system offers rapid fixing with good pullout resistance. Special side fin anchors restrict the plugs from spinning during installation. Specifications - Red fixing plugs DIM A = 34 mm DIM B = 5.5 mm - Woodscrew size = 6,8 & 10 Recommended drill hole diameter = 5.5 mm - Recorded pullout values: (pulling force required to remove fixing) - Result 1 = 3.4 kN (result 1 obtained from 6 x 2 screw & 5.5 mm hole) - Result 2 = 2.55 kN (result 2 obtained from 8 x 2 screw & 5.5 mm hole) - Result 3 = 3.3 kN (result 3 obtained from 10 x 2 screw & 6 mm hole) - Results obtained from pulling plugs from a hardened concrete fixing surface. Plug pullout limits will vary depending on the type and density of fixing surface. Results obtained from pulling plugs from a hardened concrete fixing surface.
