SMTSOB SM Fasteners

PEM SMTSOB SM Fasteners are suitable for applications that demand superior electrical / mechanical attachment points. These ReelFast® brass fasteners are available with threaded and unthreaded construction and are used to clench hardware, preventing loose hardware that can fall and short out sensitive electrical components. PEM SMTSOB SM Fasteners are marked with either "two-groove" or three-dimple" registered trademarks.
