Yellow Flat Countersunk Concrete Screws for Concrete, Brick, Block, Stone & Wood
TIMCO Concrete Screws TX Flat Countersunk Yellow are rapid, effective light-duty anchor screws designed for direct fixing into concrete, brick, stone, concrete block and wood. This through-fixing system provides a single solution and is designed to replace traditional fixings such as nylon frame fixings and hammer fixings.
Manufactured from carbon steel with a zinc plated, yellow passivated finish for increased corrosion resistance, these screws feature a TX30 drive recess to reduce driver wear and prevent cam-out during installation. Serrated V-threads help achieve optimum insertion into masonry, while the high-low thread on the first 30mm aids insertion and reduces torque.
The flat countersunk head with five locking ribs provides a secure fixing and neat finish, making these screws ideal for fitting windows, door frames and other general construction fixings where a flush result is required.
