Timco Twin-Thread Woodscrews, PZ Double Countersunk, Zinc, 12 x 3in (200 Pack)

The Timco Twin-Thread Woodscrews offer superior fastening performance with their innovative design and high-quality materials. These screws feature a double countersunk head, which significantly reduces the risk of head shear and ensures a flush finish. The twin-thread pattern with a single lead start allows for faster installation while providing greater pull-out resistance compared to standard woodscrews.

Made from C10-18 carbon steel, these screws deliver consistent quality and durability. The surface is hardened up to 750 HV to prevent torque shearing under load, while the 450 HV core hardness ensures improved ductility. The 25° sharp point and single lead design promote fast starts and superior thread acceptance in soft timber and masonry (when used with plastic plugs).

Key Features

• Double countersunk head for reduced head shear and improved countersinking
• Partially threaded for optimal grip and pull-out resistance
• 60° twin-threads with parallel shank for faster insertion
• Zinc finish for corrosion resistance
• Pozi recess (PZ3) for secure bit engagement

Ideal for soft timber applications or masonry (with plastic plugs), these Timco Twin-Thread Woodscrews are a reliable choice for both professional tradespeople and DIY enthusiasts.
