The word SEMS originated from The Illinois Tool Works Inc., which made machines that produced pre-asSEMbled washers and screws. SEMS screws (or SEM screws) are machine screws with a lock created by combining a bolt with permanently pre-attached washers to save users assembly time. They combine two separate parts into one pre-assembled, inexpensive screw.
SEM fasteners allow for fast installation, permanence, and easy adaptability to many applications with washers under the head. There's no need to worry about the washer missing when using these screws because the treads are more significant than the initial diameter, and the washer stays in place without falling loose from the bolt.
Our large, in-stock inventory includes steel and stainless-steel SEMS screws in various sizes and head styles, including hex, hex washer, and a pan head with different lengths and diameters.
Potential Benefits of SEM Fasteners
These fasteners can offer many benefits, especially when it comes to fast and easy assembly options. Some of the most significant benefits are as follows.
- No Missing Washers: Losing a washer between cracks of a machine build can be a headache with time, inventory, and cost. However, the SEMS mitigates failures related to missing washers and time wasted looking for lost components. The machine builder can assemble with confidence that the washer is secure.
- Quick and Easy Installation: SEMS allows for faster product assembly, thus boosting both your output and productivity overall. Since SEMS are complete with a washer, this makes the installation of your components faster and easier. It avoids the extra step of acquiring the suitable washer and installing it onto the screw. Especially for small spaces and designs, SEMS is very helpful, thus increasing productivity and reducing build time. In addition, they also reduce foreign object damage and lower kitting part count.
Ideal for Inaccessible Areas
You will no longer need to worry more about loose washers during repair or service and disassembly processes. It's both safer and less time-consuming, especially in some machine regions that are difficult to access.
- Less/Decreased Inventory: For some, inventory space is a luxury, and it's astonishing how much room a lot of washers may take up. In terms of inventory, not accounting for two separate part numbers is a benefit of pre-assembled screws.
- Low Cost and High-Efficiency: They have increased efficiency, easy access, and low cost as already pre-assembled.
- Versatile Nature of Use: Pre-assembled screws having vast versatility can be used in various applications ranging from battery pack assembly to laboratory automation machines.
Applications of the SEM Fasteners
- SEMS can be used anywhere where screws and washers are required.
- They are primarily used in Construction, Electrical, Automotive, and Switch Gear Industries.
- They are ideal for commercial use in homes by DIY Enthusiasts and workshops.
- They are also used widely in the electronics industry.
- Other application examples include use in the aerospace avionics sector.
