Replacement faces for the 38mm Thorex 11-712 Nylon Hammer. Simply screw to head of hammer to replace worn faces, or when an alternative face material is needed for a different application. The Thorex 11-712 Nylon Hammer becomes even more versatile when used with a variety of faces. By buying faces separately, you could have one hammer that does multiple jobs and protects the object being struck. You could even use different colour faces on either end of the hammers head, to switch quickly between striking different materials. These 38mm faces are 10mm thick with a 10mm thread, and compatible with the Thor Hammer Thorex 11-712 Nyon Hammer.
