Steel yellow zinc phillips pan head sems screws with flat washer & spring washer
Sems screws are convenient screw and washer assemblies. The washer is slipped onto the screw body during manufacturing, just before rolling the threads. When the threads are rolled, they captivate the washers and keep them from becoming disassembled. Although the initial cost per fastener may be a bit more, in high volume production you will quickly see assembly time cost savings.
