Trim Head Screw Fixing Means Lower Maintenance for Weatherboards

It is a common problem for nails to pop out on weatherboards over time. Hammering them back in, and then re-stopping and painting will buy time but eventually they pop back out again. Often the final solution is to remove the existing nails and replace them with bigger ones…unless you install with a screw the first time.

Exposed timber surfaces such as weatherboard, decking, and fencing by their nature need to expand and contract with Mother Nature. This will eventually loosen a nail's hold on the substrate, which is obvious for all to see in older decks, and eventually an issue in timber weatherboards.

For lower maintenance, use Simpson Strong-Tie’s Trim Head screws for fastening timber weatherboards. The screw's superior hold on the substrate means no more popping out issues. The Trim Head screws feature self-drilling tips, box threads, and a proprietary trim head profile that is almost identical in size to a jolt head nail. They are also all stainless steel for superior corrosion protection and ductility to allow for board movement without losing their grip. These qualities mean these screws are not limited to weatherboards, but are also ideal for window trims, door jambs, and boxed corners.

They are available in collated form for use with the Quik Drive auto-feed screwdriving system or in loose for hand-drive. They come with various sizes from 64mm to 89mm, and from 7 gauge to 9 gauge.

The collated screws are BRANZ appraised for performance you can trust, and have the added benefit of being much simpler to install. Accurate height control and countersinking mean no more marking out height and no more punching. They are suitable for NZS 3604 Extra High Wind Zones.
