Eco Timber Groups Blackheadz Screws come in a pack of 1000 including their own star head drill bit for installation. Why these screws are so unique is their ability to be self-drilling, no need to pre-drill holes before installation. This not only cuts down installation but also saves you time and money.
For use on installing cladding, lining or decking into timber fixings.
Caution – Not suitable for fixing to metal or masonary.
