View model pageGeneral guidance
In general, a countersunk head capscrew is a threaded fastener whose conical head sits flush within a matching recess so the surface stays level. Thread designations such as n.c. refer to the unified national coarse thread series, and the length and diameter are used to identify the screw size.
Use part number 0307571 as the catalog reference for this capscrew. Before ordering, check the machine model, serial number and the parent assembly conditions shown on the catalog page, since the associated entries are recorded with specific serial ranges and assembly qualifiers.
