AN 211 is a fastener consisting of a hexagonal head with a flange, a threaded rod and a drill. The product is most often used for fastening sheet metal elements to soft materials. With the total thickness of the materials to be fastened up to 4 mm, the design of the hardware allows for use without a pre-prepared hole.
Fastening group AN 211
The AN 211 self-tapping screw belongs to the stainless steel fastening group.
Materials of AN 211
AN 211 is available in the following materials:
- Steel, which can be optionally coated with zinc
- Stainless steel (A2, A4) does not need to be coated
Areas of application of AN 211
Hexagonal head drill screw AN 211 - This screw is used for fastening several structural elements to profiles and metal sheets. No pre-drilling is required. If this fastener is equipped with a rubber gasket, it can be used as a roofing fastener. Since the gasket will protect the connection from the effects of adverse weather conditions, it will ensure tightness, reliability and durability of the structure. It is used in various industrial sectors, in construction, repair and installation processes, in mechanical engineering, during the assembly of metal structures, various installations, equipment, roofing, etc.
In addition, the scope of application directly depends on the material of manufacture and coating of the product:
- Galvanized steel is a good protection against corrosion if the fastener is to be used in an aggressive environment.
- Stainless steel allows the fasteners to be used at significant temperature drops and in aggressive and humid environments.
