Wall anchor that can be directly driven into standard gypsum board (GB-R) with an impact driver.
The Wall Anchor "Ichigeki" is a casing-type metal anchor that does not require a pilot hole. With regular wall anchors, it was necessary to drill a pilot hole before installation, but with Ichigeki, you can directly drive it into standard gypsum board (GB-R) using an impact driver. This greatly improves work efficiency, especially for tasks like installing indoor air conditioning units. ■ No pilot hole needed Since there is no need for a troublesome pilot hole, you can install it just like driving screws into gypsum board. No drill for pilot holes is required. *If used with materials other than GB-R, a 9mm diameter pilot hole is necessary. ■ Compatible with impact drivers You can use a 7.2V pen-type impact driver. This allows for incredibly fast and easy installation. *Only the 7.2V pen (stick) type can be used. Using anything else may cause wall damage or installation failure. ■ Ideal for indoor air conditioning units Since no pilot hole is needed, you can mark and drive it in immediately. The tip of the Ichigeki screw is sharp, making positioning easy.
