Washers, grips and brackets in Catherine Field NSW

A tie down chain is only as good as the pieces holding it together, and those pieces cost almost nothing. A washer spreads a bolt's load across the timber face instead of concentrating it under the bolt head. A triple grip ties a truss to the top plate so uplift is resisted at every truss rather than by skew nails. A bracket is only as strong as the fixings actually driven into it. The Leppington frame records two and a half kilometres from here contain all three: washers missing, triple grips recorded, bracket fixings recorded. None of them would be visible a fortnight later.

Washers, grips and brackets in Catherine Field NSW: common questions

Could I count these myself?

With the tie down schedule in hand and a torch, some of it. Reading a grip's fixing pattern against what the manufacturer requires is the part that takes practice.

Do builders argue about hardware?

Rarely, at frame stage, because the parts cost cents and the correction takes minutes. They argue about it after lining, which is the whole point of the timing.

Which standard covers it?

AS 1684, together with the bracing and tie down schedule that comes with your engineering and the manufacturer's fixing requirements for each connector.
