Superior to nails in holding power and pullout resistance

SDWS FRAMING Screw

The SDWS Framing screw is suitable for replacing nails in many framing applications where you are wanting a more secure and precise connection, especially if you require greater holding power and pullout resistance, it can also be easily removed if required.

The screw has a SawTooth™ point that makes for fast installations without predrilling, and its specially designed head countersinks easily to provide a clean, flush finish. The T25 bit holds the 6-lobe recess tightly, reducing cam-out and head stripping.

SDWH TIMBER-HEX Screw
The SDWH19 Timber-Hex screw is ideal for structural and general purpose timber frame applications where a hex-head drive is preferred. 

The SDWH27 Timber-Hex screws are also available with an extra strong shank and have a Hot-Dip Galvanised finish for when you require a heavy duty fastener for tough exterior structural applications.
