Twister Screws Premium Double-Threaded Wood Screws | 4mm x 25mm | Box of 50 | Self Drilling, Self Countersinking, Zinc-Plated, Ultra Sharp Quick Grab Point

CLEAN FLUSH FINISH - Patented Magic Spiral head cuts into timber as it drives, clearing wood fibres to help the screw sit neatly flush without separate countersinking in most indoor jobs. FAST, SMOOTH DRIVING - Patented Twister thread reduces friction and driving resistance, helping screws go in quickly while pulling wood and board materials firmly together. Zinc-Coated Indoor Screw Finish - Bright zinc coating supports smoother driving with reduced torque, making these screws suitable for dry indoor applications such as cupboards, wardrobes, drawers, shelving, shopfitting, and internal woodwork. QUICK-START TYPE 17 POINT - Sharp Type 17 point bites fast for accurate placement, helping reduce slipping, wandering and the need for pilot holes in many timber and board applications. SECURE PZ2 DRIVE GRIP - Deep Pozi 2 recess helps reduce cam-out, while the waxed zinc coating gives smoother, lower-torque driving for furniture, cabinetry and general indoor woodworking.
