1.4 Screws

Important Information

1. Only screws with cylindrical heads are suitable for mounting the tag. We do not advise using counter-

sunk screws. If for some reason this should be necessary, then use only with a suitable counter-sunk

cushioning disc (refer to UN 1277).

2. Secure the screws with self-locking nuts, spring washers or Nord-lock washers (refer to UN 7014). Should

mounting be completed with self tapping screws, loosening may occur over time.

3. If the tag is mounted outdoors or in a damp environment, all mounting parts need to be made of

stainless steel or other non-rusting material.

4. A temperature of at least +10 °C (+50 °F) must be maintained during mounting to prevent the casing

from cracking.

5. Recommended maximum torque

M4/ #8 (with bushing): 2 Nm

M5/#10 (w/o bushing): 3 Nm

M6/#14 (w/o bushing): 3 Nm

If the torque is any greater, the screw may over tighten, or the casing might break.

6. Metal surfaces in direct proximity to the tag may reduce the tag’s range of function. Tags should not be

mounted in metal recesses or corners.

7. After mounting, the tag’s function should be tested with appropriate devices and software.

e.g. 5/32‖ hexagonal locknut with 5/32‖ washer

5/32‖ hexagonal nut, but together with spring washer

or 5/32‖ Nordlock washer

e.g. M4/#8 cylinder head or lenticular head screws
