Description
We have selected the most popular sizes of holding down bolts, also known as foundation bolts, and combined them into a ready-to-use package.
We manufacture our standard holding down bolts from grade 8.8 high-tensile steel, and they fully comply with BS 7419. In addition, we can supply bolts in galvanised steel or stainless steel, in sizes up to M72. If required,
For further information please contact us.
Method of fixing:
First, place the waxed cardboard void former over the bolt so it sits on the square plate washer. Next, leave the cone in position while the concrete sets. This allows lateral movement of the bolt and makes alignment of the above-ground structure much easier. Finally, fill the void with grout once positioning is complete.
Comprises:
1 x bolt (8.8 high tensile steel), nut and round washer
1 x square plate washer
1 x waxed cardboard cone
PLEASE NOTE: These ‘sets’ are supplied as individual components.
