Superior to nails in holding power and pullout resistance

The SDWS16 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 T-25 bit holds the 6-lobe recess tightly, reducing cam-out and head stripping.
