- Pan Head Phillip SEM Machine Screws are created by combing a screw with a permanently affixed set of washers. The washers stay in place due to the fact they are installed on the blank screw before the thread rolling is conducted. Because the threads are larger than the initial diameter, the washers stay in place without falling loose from the screw. It is normally possible for the washer/washers to slide on the non-threaded part of the bolt
- Length: The length includes the thickness of the 2 washers which is approx. 1.90mm, if you are ordering a 12mm long screw, the working thread length remaining will be approx 10.10mm
- Features / Benefits:
- SEMS screws can allow for faster assembly of products due to their pre-assembled and lubricated parts. This can boost both your output and productivity overall.
- The custom fastener options can also help decrease failures related to improper mounting or missing washers. Because SEMS screws have permanently affixed washers, or sets of washers, any failures related to missing washers is highly mitigated.
- SEMS screws work well in products with small dimensions, allowing for seamless integration and assembly with a lower risk of error or failure.
- Service on parts that are difficult to reach can also benefit from SEMS screws, as they can help make the process easier and safer.
- Inventory and logistics can be easier to accurately keep track of as washers and screws won’t have to be accounted for separately.
- Disassembly is also made considerably easier as you won’t have to worry about loose washers getting lodged or stuck in tapped holes.
- The term SEMS: Originated with The Illinois Tool Works Inc. a company that specialized in machines that created pre-assembled washers and screw combinations
- Material / Coating: Zinc Plated is the most common fastener of plating due to its the low cost and shinny bright silver finish. A thin layer of Zinc is applied by either electroplating or mechanically. It is intended to be used internally
