Timco Twin-Threaded Woodscrews, PZ, Zinc, 5x5/8in (200 Pack)

Timco Twin-Threaded Woodscrews deliver exceptional performance for quick and secure fastening in soft timber and masonry (with plastic plugs). These premium woodscrews feature twin-thread design with a single lead start to ensure fast, one-pass installation without the risk of cross-threading. The double countersunk head not only provides a neat finish to your woodwork but also reduces the likelihood of head shear during installation or under load.

Forged from C10-18 carbon steel, these screws undergo surface hardening to 750 HV to resist shear forces while maintaining a core hardness of 450 HV for improved ductility and durability. The 60° twin threads combined with a parallel shank significantly improve pull-out resistance, making them ideal for demanding applications where structural stability is critical. Each screw features a 25° sharp point and single lead start for easy penetration and superior thread acceptance in both softwoods and composite materials.

Key Technical Features

• Double countersunk head: Reduces head shear risk while ensuring cleaner countersinking
• Partially threaded on longer lengths (1 1/4” and above) for better material retention
• Pozi (PZ) drive recess: Ensures positive engagement with PZ2 driver bits for improved torque transmission and reduced cam-out
• Zinc-plated finish: Provides moderate corrosion resistance for interior applications
