Stainless steel accessory shoe replacement screw for all Leica 'M' up to M4. Your Leica may have been serviced several times in the past. The original chromed, soft brass screws were easily damaged if the incorrect screwdriver was used. Damaged screws heads suggest poor maintenance that's why our precision replacement screws are made from stainless steel. There is no chrome to flake off and the polished screw heads are more resistant to marring. Sold in a pack of four.
