Timco Twin-Thread Woodscrews, PZ Double Countersunk, Zinc (10x100mm, 6pc)

The Timco Twin-Thread Woodscrews combine traditional design with modern engineering for superior performance in woodworking applications. These partially threaded screws feature an innovative twin-thread design with single lead start for faster installation while maintaining excellent pull-out resistance.

Specifically designed for soft timber and masonry (with plastic plugs), these screws feature a double countersunk head that reduces the likelihood of head shear and ensures clean, flush finishing. Made from C10-18 carbon steel with surface hardening up to 750 HV, they're built to withstand torque stresses while maintaining ductility with a 450 HV core hardness.

Key features include a 25° sharp point for fast starting and improved thread acceptance, plus 60° twin-threads on a parallel shank for faster insertion. The Pozi (PZ) drive recess provides excellent torque transfer with reduced cam-out risk when used with the correct PZ2 driver bit.

Ideal for:

• Fast wood-to-wood joinery
• Fixing timber to masonry (with appropriate plugs)
• Applications requiring flush finishes
• Projects needing reliable pull-out resistance

Supplied in a convenient pack of 6 screws with a corrosion-resistant zinc finish.
