Timco 40025CHYP Chipboard Screws 4.0 x 25 Pack of 30

This is a single thread woodscrew designed for use in timber, man-made boards, or masonry with a plastic plug. It features a double countersunk head to reduce the likelihood of head shear and aid countersinking, and it is wax-lubricated to improve screw insertion time, provide extra driving torque, and enhance corrosion resistance. The screw has a 40° deep single thread that delivers a secure fixation with high pull-out resistance, and a 25° sharp point with a single lead to promote a fast start and better thread acceptance. Sizes up to 75 mm are fully threaded, while lengths of 80 mm and above have a 70 mm thread length, offering flexibility for various fixing depths.
