Technical Note
Proper torque values for a wood screw will vary depending on the rafter and/or deck
characteristics; hardness, age, and moisture of the wood. Tighten the M5x60mm
wood screws until the conical washer stop rotating.
Stainless hardware is soft and if dry torqued too quickly it may cause the nut and
bolt to seize.
Roof Tech recommends all stainless steel threads be lubricated. This will make it
easier to tighten nuts to bolts, avoid galling, and facilitate adjustments before the
nut is properly torqued. Therefore, avoid the use of an impact driver.
When driving the RT 5x60mm or 5x90mm into the wood, always keep a hand
pressure on the RT MINI II in order to avoid the base being pulled away from the
roof surface.
