Discover Carpenters Mate - The original self-drilling wood screw

Carpenters Mate® is the original self-drilling wood screw. With no need for pre-drilling – and the correct drive tool included free with every pack – Carpenters Mate wood screws help make laying flooring and decking, carrying out loft conversions, repairing roofs and erecting fences quicker, cleaner and easier than ever before.

Designed specifically to provide a professional finish with standard UK timber sizes, Carpenters Mate screws sit flush with the wood and ensure a secure yet flexible connection that allows the wood a degree of elasticity to accommodate the stresses and strains of structural movement.

Renowned for their quality, convenience and durability, Carpenters Mate self-drilling screws are proven to stand the test of time – even in the harshest of outdoor environments. Rated by the trade as the strongest and most reliable timber screws on the market, Carpenters Mate products are tried and trusted by professional carpenters and tradesmen who need a durable fixing they can rely on.
