TIMCO Twin-Threaded Countersunk Silver Woodscrews - 12 x 4 - Pack of 100 Pieces | B2604

TIMCO 00124CWZ Twin-Threaded Countersunk Woodscrews, Silver, 12 x 4 (Pack of 100)

TIMCO 00124CWZ twin-threaded countersunk woodscrews are designed for fast fixing in soft timber and can also be used in masonry when paired with a suitable plastic plug. The twin-thread design and single lead start help the screw bite quickly for efficient installation on site and in the workshop.

This TIMCO twin-thread woodscrew features a partially threaded design and a double countersunk head to help reduce the likelihood of head shear while supporting a neat, flush finish. Size 12 x 4 makes it a practical choice for general wood fixing where a strong hold is required.

Key Features

• Twin-thread design: 60° twin threads with a parallel shank help drive the screw in faster and improve pull-out resistance.
• Single lead start: Helps the screw start quickly for efficient installation and improved thread acceptance.
• Double countersunk head: Reduces the likelihood of head shear and helps complete countersinking for a flush finish.
• Partially threaded: Partially threaded from 1 1/4" and above for applications where a clamping effect is beneficial.
• Hardened for strength: Surface hardened up to 750 HV to help prevent torque shearing under load, with core hardness up to 450 HV for improved ductility.
• C10-18 steel construction: Made from C10-18 steel to help ensure consistent quality.
