DIN912 cap socket head sems screw with captive washer, stainless steel sems screw with flat washer and sping washer

1. Descriptions:

Screw and washer assemblies also called SEMS screws, As part of our specialty fastening solutions, we manufacture a range of SEMS fasteners suitable for automotive and electronic assembly applications. SEMS fasteners can be produced in a combination of screw and captivated washer assemblies. Captivated washers help in eliminating instances of lost or dropped washers during assembly operations, which in turn improves productivity. We have the ability to manufacture SEMS screw and washer assemblies in various combinations based on your specific head style, washer style, material, thread style, and plating type requirements.

Our preassembled SEMS fasteners are available in standard lengths up to 6” with pitch values up to 18tpi. Besides standard sizes, we can also manufacture specialty fasteners according to your custom dimensional needs. Some of our washer types include external tooth, internal tooth, combination of internal/external tooth, flat, and doomed washers. For severe environments, washers can be aslo manufactured from stainless steel.

3. Applications:

Combination screw material usually for iron and stainless steel, the biggest advantage is with the corresponding gasket, can make the production line operation convenient, improve work efficiency, and therefore is widely used in electric, machinery, furniture, ships, etc.

Overall to combination screw is widely used in electric, electric power, machinery, electronics, home appliances, furniture, boat ship and so on.But it says the combination of different screw has different functions.Such as cross combination of pan head screw, generally used in small electronic products.Bigger cross outer hexagonal screws used in large electric products, such as frequency converter, some big inverter above is useful to many cross outer hexagonal screws.Playing on the inverter cabinet.Make relax fastening effect.In brought flowers 2 combination screw tooth, such as the use on the frequency converter, function is used to break the paint, make the second combination screw on the chassis panel all electricity.Still, such as the quartet line pressing combination screw, it itself is a pan head screw with a square pad 2 combination screw.Is commonly used in the terminal in the following.Function is used to wire, used for line pressing.

4. Advantages:

1, the screw is not easy to change under the action of external force, so can reduce the time of the assembly and maintenance time of late.
2, has a larger torque transmission capacity, to avoid the unnecessary waste and not damage caused by the damage on the surface of the screw head electric plating.
3, at the time of twist screws, reduce the labor personnel section load force and energy consumption.
4, elliptic geometry structure increases the safety coefficient of twist screws.
5, reducing the stop waiting for the assembly line, the possibility of rework and scrap.
