This steel tapered pin aids the insertion of piercing jewellery. The length of the pin is 51mm and the widest end contains a recess into which you push your desired piece of jewellery. To use the insertion pin, push the thinner end of the pin into your piercing and thread all the way through until your jewellery is in the correct position. If your jewellery does not quite fit into the recess, just allow your jewellery to follow the pin as you push the pin through your piercing. This normally takes time - please do not rush.
Note that the outside diameter (OD) of the widest end is slightly thicker than the gauge of the bar it is designed for - for example, our 4mm taper accepts a 4mm bar inside the recess because the recess is slightly wider at 4.15mm. The outside diameter of the insertion pin is wider still, at 4.65mm. With all sizes of insertion pin you may notice this slight stretch when inserting the widest end of the pin through your piercing and you may feel a little discomfort as a result, but this is normal and once your jewellery has been fully inserted, your piercing will settle at its correct gauge of 4mm.
Please note that the sizes below can vary by up to 0.2mm.
