Product Description
SEMS screws (or SEM screws) are machine screws with lock washers pre-attached to save users assembly time. They combine two separate parts into one pre-assembled, low cost fastener. With washers under the head, SEM fasteners allow for fast installation, permanence, and easy adaptability to many applications. When using SEMS machine screws, there's no need to worry about the washer going missing; this, in turn, helps extend product life and ensure reliable performance.
