DIYUK 4.0 x 40mm Countersunk Torx Wood Screws, Yellow Zinc, Pack of 200 | Sharp point, deep coarse thread and ribs under the head for a flush finish in softwood, hardwood and boards

Quick, clean start: the sharp, self-piercing point starts the screw quickly and helps prevent the timber splitting near an edge; in softwood and boards such as MDF, chipboard and plywood it normally starts without a pilot hole Strong hold: the deep, coarse thread cuts its own path through the timber as it drives, for strong pull-out resistance Flush finish: ribs under the countersunk head prepare the surface and seat the head flush with the timber, with no pre-countersinking needed Torx drive: the star-shaped recess gives deep, positive bit engagement for stable driving, reducing cam-out, stripped recesses and bit wear compared with a Pozi or Phillips cross-head Size and pack: 4.0 x 40mm (8g x 1 5/8in), pack of 200 yellow zinc-plated steel wood screws; the zinc coating gives useful corrosion resistance 10 sizes to choose from: 3.5 x 25mm, 4.0 x 40, 50 and 60mm, 5.0 x 50, 60, 80, 100 and 120mm and 6.0 x 200mm, each in packs of 5, 20, 100, 200 or 400 For carpentry, joinery and furniture: general carpentry and joinery in softwood, hardwood and manufactured boards, furniture assembly, fixing boards and linings to walls and timber frames, and flooring and sheet material in MDF, chipboard and plywood
