DIN125 Metric Flat Metal Washers , Colored Curved Washers With Iron Material
The flat pad, which is mainly punched out with an iron plate, is generally a flat washer with a hole in the middle. This hole size specification is generally based on customer requirements.
Flat washers are usually thin pieces of various shapes to reduce friction, prevent leaks, isolate, prevent loosening, or distribute pressure. This material is used in many materials and structures to perform a variety of similar functions. Due to the limitations of the material and process of the threaded fasteners, the bearing surfaces of the fasteners such as the bolts are not large, so that the surface of the parts to be joined is protected to reduce the compressive stress of the bearing surface, and washers are used. In order to prevent loosening of the connection pair, loose-proof spring washers and multi-tooth lock washers, round nut stop washers and saddle-shaped, corrugated, conical elastic washers are used.
Flat washer is generally used in fitting a soft texture, is a hard and brittle, its role is largely increase the contact area, dispersing pressure, prevent the quality of a material soft crush.
Flat mat is: 1, increase the contact area of the screw and machine 2, eliminate the trampoline at the time of discharge screw damage on the surface of the machine.Must be: when using a flat pad, spring pad flat pad close to the surface of the machine, spring cushion between the plain washers and nuts. Flat pad is in order to increase the screw surface.Spring pad to prevent screw loosening, force when a certain amount of buffering effect. Although flat mat can do sacrifice pad.But more often is used as supplement pad or flat mat.And the spring pad a lock.Such as the workpiece hole diameter value and the screw diameter is too large when not using a flat mat or direct use of spring washers, will not only harm the artifacts.
Flat washer is generally used to distribute the load of a threaded fastener, such as a bolt, scres or nut. Other uses are as a spacer, spring (wave washer), wear pad, preload indicating device, locking device, and to reduce vibration , rubber washer. Washers usually have an outer diameter (OD) about twice larger than their inner diameter (ID).
The Role of Flat Mat
1. Increase the contact area between the screw and the machine.
2. Eliminate damage to the surface of the machine when the spring pad is unloaded. When used, it must be a spring pad and a flat pad. The flat pad is facing the surface of the machine. The spring pad is between the flat pad and the nut.
Flat pad standard
National standards are different.
Here is the United States flat pad standard:
