The one diameter fixing, from 50mm to 250mm long, will perform well even in standard roof truss widths of 30mm thickness. Grade 304 austenitic stainless steel material will resist attack from any timber treatment finishes and will not corrode in damp conditions.
The simple one piece fixing drives like a nail with a hand tool available for lengths over 130mm. They can also be driven using a power driving tool attached to a SDS drill.
Fixing specifications are given in the more details section.
