Anchors
Anchors are fastening components used to fix equipment and brackets to base materials that cannot hold screws directly, such as concrete and ALC (autoclaved lightweight aerated concrete). A pilot hole is drilled in the base material, the anchor is inserted, and holding force is obtained through expansion, biting, or threading. The listed products include screw-in anchors that thread directly into concrete without a plug, and screw-fixing anchors whose body bites into ALC so that bolts or wood screws can be tightened into the internal female thread. Both types can be installed with an impact driver. Applications include fixing electrical, air-conditioning, and sanitary equipment and piping, fixing metal rafters and hanging brackets, and installing handrails and bird-protection nets.

How to choose Anchors
-
1. Select a matching bolt for the base material and fixture
ALC anchors have a fixed bolt nominal diameter for each size. The listed products are grouped as M4, M5 to M6, M8, and M8 to M10. Select the type that matches the hole diameter of the bracket being fixed and the nominal diameter of the bolt you use.
-
2. Compare required load with the tensile strength guide
The guide tensile strength for the listed products when used with bolts is 1.8 to 3.5 kN. Select with a margin by including the weight of the fixture as well as loads from earthquakes and vibration. The values shown are guides only, and actual strength varies with the condition of the base material and installation accuracy.
-
3. Determine the neck length from fixture thickness plus embedment depth
The under-head length of the listed screw-in anchors is 35 to 150 mm. Choose a length equal to the thickness of the bracket or rafter being fixed plus the required screw-in depth in the concrete. If the length is insufficient, holding force will be inadequate; if it is too long, the pilot hole becomes deeper and installation takes more effort.
-
4. Maintain the correct pilot hole diameter and depth
The listed products require a pilot hole diameter of 10 to 14 mm and a pilot hole depth of 60 to 80 mm. If the hole is too large, biting force will be insufficient; if it is too small, the base material may crack or the anchor may not thread in. Use a bit of the specified diameter and drill to the specified depth.
-
5. Embedment depth, body diameter, and edge distance in the base material
ALC anchors have a total length (embedment depth) of 50 to 70 mm and a body diameter of 15 to 22 mm. Larger sizes generally achieve higher strength, but they also require greater base material thickness and edge distance. Check the thickness of the ALC panel and the distance from the edge at the installation position.
-
6. Check the installation bit and recess
Some types require a dedicated high-speed bit, and some have a drive recess in the head that accepts square bits. Confirm in advance that your impact driver bits fit, so that installation does not stop on site due to incompatible tools.
