Clenergy Self-drilling Universal Wood Screw 14-11 x 70 Hex Head

This is Clenergy's self-drilling universal screw for the PV-ezRack mounting range, a Buildex 14-11 x 70 hex-head fastener with an integral 16mm ABW (anti-back-out washer) and Climaseal 3 corrosion-resistant coating. The self-drilling point cuts its own pilot hole, so no separate drilling or tapping step is needed when fixing rails or brackets to timber roof structures. Its hex head with bonded washer gives a positive drive and a weathertight seal at the fixing point in a single action, and the corrosion coating suits long-term outdoor use on pitched and low-slope roofs. This screw is sold as an individual PV-ezRack accessory item rather than as part of a kit, for topping up or replacing fixings on Clenergy rail installations.
