Fitting Information
Drill a suitable pilot hole before installation, selecting the hole size and depth to suit the timber and screw. Allow adequate clearance for the plain shank where required, and position fixings with sufficient distance from timber edges and ends to reduce splitting.
Drive using a 13mm spanner or socket. A suitable washer beneath the head can help spread the bearing load. Tighten steadily without overtightening or crushing the timber, and choose a length that provides sufficient thread engagement in the receiving timber.
