Bi-metal Self Drilling Screws with hexagon washer head combined with a EPDM bonded washer ,full tapping threads with drilling point that can cut and drill fast into metal sheet in a power drill .

 

Bi-metal self drilling tapping screws are made in two different materials for combination of durable corrosion and strong hardness . Normally , Bi-metal self-drilling tapping screws are made of stainless steel but drilling point is made from carbon steel so that screws can be capable of drilling metal sheets smoothly and work for a long time .

 

 

Typical Features

 

1 Strong hardness

 

2 Perfect durable corrosion

 

3 Recyclable

1 , We offer non-standard sizes as well .

2 , Bonded EPDM  washer is optional .

 

 

Bi-metal self-drilling tapping screws must to be plated a film protective finish to prevent screws from rusting and extend service time . we supply different finish for different applications , you can make a right choice according to the characteristic each kind .

 

1 , Zinc 

This is popular finish and various colors for choice . The resistance of rust is good and eco-friendly .

 

2 , Nickel 

Nickel finish makes the surface of the screws will more bright and hardened and the performance of screws will be improved .

 

3 , Polishing

Bi-metal self-drilling tapping screws can be polished after forming for getting a bright surface and anti-rust purpose , but it is not good as other finishes on anti-rust . polish is usually for stainless steel screws.

 

4 , Tin 

It is very perfect to be anti-rust , and widely used to components .

 

5 , Brass 

It is available for stainless steel screws and carbon steel screws and perfect on durable corrosion .

 

6 , Dacromet

This finish is used for screws with big sizes and can stop screws to be rusted long time even under bad surroundings .

 

 

More options for bi-metal self-drilling tapping screws

 

Stainless steel : SUS 201 , SUS303 , SUS 304 ,SUS 316 , SUS 416 ,SUS 430 and SUS 420 .

 

Carbon steel : 1018 , 1022 , 1035 , 1045 , SCM 435 and 40CRO

 

 

Bi-metal self drilling tapping screws are used to drill sheet metal should be considered the thickness of sheet and make sure enough torque to finish secure .
