This GM-style metric hex head SEMS screw features an M6-1.0 thread and 16mm length for compatible automotive fastening applications. The preassembled 17mm-diameter washer provides a broader bearing surface while keeping the screw and washer together during handling and installation.
The screw has a black finish and a 10mm hex head measured across the flats. It cross-references GM OEM number 11508930; verify the thread size, length, washer diameter, hex size, finish, and OEM reference before installation.
