No4 x 1"- Woodscrew Hardened Pozidrive Countersunk Twinthread - BZP - Pack of 200

These No4 x 1" woodscrews are manufactured from high quality steel and all feature a bright zinc plated and clear passivation finish. They have a pozidrive countersunk head and 25 degree sharp point for efficient screwing into softwood. Countersunk twinthread woodscrews are one of the few types of woodscrew that can be used when fixing into masonry, but only when using them in conjunction with a plastic wall plug. Their twinthread allows them to be driven into wood easier and faster than traditional single thread screws, and their countersunk heads provide a smooth finish on the substrate.
