How to choose Insert

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

1. 1. Thread size matching the workpiece hole diameter

   The insert is held in the workpiece's threaded hole or bore, so if the nominal diameter (such as M6) does not match, holding force will be insufficient or insertion will not be possible. Check the thread diameter and hole depth on the workpiece drawing, and select a product with the same nominal diameter.

2. 2. Choosing a shape that suits the holding method

   Arrow types are inserted into threaded holes and held by elasticity, while hook and yoke types are hooked onto a hole or edge to suspend the workpiece. Determine the shape by checking the shape of the workpiece's holding section and which surfaces may be hidden by paint. Also confirm the compatible cap series.

3. 3. Wire diameter according to load

   A thicker wire diameter increases rigidity and reduces deformation under heavy workpieces. However, thick wire will not fit into narrow holes. For heavy items, select thicker, high-rigidity heavy-duty series; for small items, select thinner diameters, and balance this against the hole diameter.

4. 4. Overall length and insertion depth

   The overall length is determined by the insertion allowance into the cap, the insertion depth into the workpiece, and the distance between the workpiece and the hanger. If it is too long, swinging and contact will occur; if it is too short, holding will be shallow. Also consider the workpiece spacing on the line when selecting.

5. 5. Checking suspended mass

   If the rated load is exceeded, the insert may bend and the workpiece may fall. Add the mass per workpiece, with allowance for paint buildup and swinging during conveyance, and compare the total with the rated load.

6. 6. Baking temperature and ensuring electrical continuity

   Confirm that the baking oven temperature is at or below the heat resistance temperature. In powder coating and electrodeposition coating, the insert serves as the electrical or grounding path, so paint buildup causes poor continuity. Decide in advance the interval for stripping or replacing the inserts.
