Tongue-Tite Star Drive Lost Head Floorboard Screws 3.5 x 49mm 200 Pack Product Code: 4162H

Corrosion-resistant, stainless steel tongue and groove board screws. Lost head allows the screw to be driven, without a pilot hole, into the tongue without splitting the board. Twin thread tip for a balanced and true start. Tri-Lock TS thread eliminates timber split and thread form prevents the board from lifting. Fixes flush as the screw seats beneath the tongue and is removable. Ideal for exterior cladding and boards. Supplied with T10 driver bit.

Tongue-Tite Star Drive Lost Head Floorboard Screws 3.5 x 49mm 200 Pack is rated 4.8 out of 5 by 5.
Rated 5 out of 5 by from Lots of uses beyond flooring Having always secret nailed using floor clamps in the past; really wish I'd found these earlier. They pull the boards together brilliantly... impressed with how they tightly pulled solid oak planks flush. Great for skirting board too. They leave a tiny hole. Ignore the 'no need for pilot hole' and save yourself the inevitable split every so often.

Rated 5 out of 5 by from These are tiny but work Putting carpet over 50 year old squeaky boards could have been trouble but these have worked a treat. No split wood and have a better hold that expected
