Blue Ceramic Hex Washer Head Concrete Screw
3/16" and 1/4" hex washer head masonry screws with blue ceramic coating and Hi-Lo thread.

Concrete screws cut their own thread in a pre-drilled hole in concrete, brick or block, so no plug or anchor is needed and the fixing can be removed. A hardened high-low or serrated thread keeps installation torque low and holding power high.

Three decisions that prevent most problems on site.
Drill the hole to the diameter we specify for each screw (for example 5/32" for 3/16" screws, 3/16" for 1/4"). An oversized hole costs most of the pull-out strength.
Allow at least 25 mm embedment for light fixings and 32–44 mm for structural ones, and keep 2× embedment from free edges.
Blue or silver ceramic coatings suit interior and protected exterior use. For wet or treated concrete use stainless bi-metal screw anchors.

Collated and loose screws for partitions and ceilings where speed and consistent countersinking drive the schedule.

Concrete screws that replace plugs and anchors for windows, doors, battens and electrical fixtures.
No. They tap their own thread directly into the masonry hole. Only the drill hole is needed.
They can be removed, but we recommend a new screw for structural re-installation because the thread wears.
