The TIMco Twin Thread Zinc Countersunk Woodscrew is designed for general use in softwood and various types of hardwood. Featuring a double countersunk design and zinc plating, it offers durability and corrosion resistance. The twin thread design enables faster insertion and greater pull-out resistance, making it suitable for a range of applications. Sized at 6 x 1/2, it is manufactured from C10-18 steel and designed to perform with a fast start and reliable threading, while maintaining ductility under load. The screw incorporates a 25° sharp point and a single lead, and is produced to BS 1210 standards for compatibility with plastic expansion plugs and common installation practices. Its construction emphasizes ease of penetration and reduced head shear during countersinking, supported by a 24-degree sharp end and a partially threaded portion from 1 1/4

Details

Made from C10-18 steel to ensure consistent quality, the screw has surface hardness up to 750 HV and core hardness up to 450 HV, providing improved torque resistance and ductility. It is designed for easy penetration and thread acceptance due to the 24-degree sharp end and single lead thread, and its double countersunk head helps minimize head shear and aids countersinking. Suitable for TIMco and other leading plastic expansion plugs, this traditional twin-thread woodscrew is commonly used in soft timber applications or masonry with plastic plugs, offering faster insertion and greater pull-out resistance.
