A phosphate finish surface treatment provides outstanding surface protection; higher accuracy in the tip. Supplied in a compact sleeve-case for instant selection of the required size. It allows easy storage, whilst keeping the keys together. Sizes: 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm and 10mm. Ref: UTTK2202
