Timco Twin-Thread Woodscrews, Zinc Plated, Size 8 x 1 1/2, Pack of 20
Fast, durable Timco woodscrews—twin-threaded, zinc-plated, and countersunk for secure timber & masonry fixing.
The Timco Twin-Thread Woodscrews are designed for quick and secure fastening in soft timber or masonry applications when used with plastic plugs. Featuring a double countersunk head, these screws minimise the risk of head shear and ensure a flush finish when countersinking. Constructed from C10-18 carbon steel, they offer consistent quality and durability.
