The nominal diameter of the pin is the same as the receiving hole diameter. The recommended hole tolerance is ISO H12. Due to the chamfered end, the pins can be inserted easily into the hole with a hammer or using automatic placement. After insertion, the plus tolerance of the pins results in a vibration-proof seating. The pins can be easily removed using a mandrel and reused several times. The pins can transmit high shear forces and are resistant to shocks and impacts due to their spring properties. The values specified for the shear force only apply to spring steel.

The lateral spring plunger must be pressed into the hole to at least depth L3. These plungers are for positioning and holding small parts in fixtures. If mechanical machining of the workpiece is to be carried out, other clamps may be necessary. When the fixture is not in use it should be ensured that plastic springs are not under stress. Spring force refers to a mean value.
