Set-screws are used in a variety of tools we carry like screwdrivers and pin-punches. The set screw, used for holding blades or pins in collets or screw-driver bodies, is extremely small. The thread diameter is 3.00mm and we recommend having a 1.60mm or 2.00mm screwdriver on hand when installing it but you may be able to get by with as large as 2.50mm depending on the application. Sold in package of 2.
