How to choose Screw-in anchors

Points to check when selecting, with the values for this product (TP1212).

  1. 1. Select the bolt diameter to suit the attachment

    Determine the nominal diameter of the projecting metric thread (e.g., M6 to M12) according to the hole diameter and bracket specification of the attachment. The nominal diameter also changes the anchor thread diameter, pilot hole diameter, and nut width across flats for the tightening tool, so check these together.

  2. 2. Confirm the required pull-out load is met

    This product: Pull-Out Load 18 kN

    The listed products have pull-out loads of 6 to 18 kN. For hanging or ceiling installations, pull-out is the main load direction, so compare the value with the attachment weight and seismic loads including a safety factor. Also confirm the base strength and conditions under which the stated values were measured.

  3. 3. Check base type and embedment depth

    This product: Embedment depth 50 mm

    Holding capacity depends heavily on the base material and embedment depth (30 to 50 mm for listed products). Some examples show a maximum tensile load of about 1 kN in ALC and about 4 kN in lightweight block columns, which are much lower than in concrete, so always verify the compatible bases and the load values for each base.

  4. 4. Install with the specified pilot hole diameter

    This product: Drill diameter (pilot hole diameter) 11.0 mm

    The pilot hole diameter (5.5 to 11 mm for listed products) determines how far the threads bite into the base. A hole that is too large results in insufficient holding capacity, while one that is too small can prevent screw-in or cause damage. Use the drill diameter specified by the manufacturer, and note that even types without a pilot hole may require one depending on the base.

  5. 5. Choose a length that suits the attachment thickness

    This product: Maximum thickness of workpiece 47 mm

    Overall lengths range from 45 to 120 mm, and different lengths are available for the same nominal diameter. After securing the required embedment depth, select the length so that the attachment thickness (up to 5 to 70 mm) and the projecting thread length needed for the nut and washer are both accommodated.

  6. 6. Check shear load and material

    This product: Shear load 37 kN

    For applications with lateral forces, such as fixing brackets to walls, check the shear load (7 to 37 kN for listed products). For outdoor or humid locations, check whether steel-only or stainless steel versions are available and select a material suited to the corrosive environment.
