DIN 125 A Flat Washers, without chamfer, are a slender circle with a concentric opening and are perhaps the most well known level washer. When set under a nut or the top of a screw, the washer expands the bearing surface region and thusly disperses the cinching power over a bigger region.
That outcome is helpful when working with delicate materials and openings that are excessively enormous or strangely molded to appropriately uphold the screw head or nut. “Without chamfer” shows that the external edge on one side isn’t slanted. Steel in 140 HV, 200 HV and 300 HV, either zinc plated or plain completion (which needs rust assurance), and tempered steel can be provided. Washers with a Hardness Class of 140 HV ought to just be utilized with screws/screws underneath Class 8.8 and nuts beneath Class 8; 200 HV washers are reasonable for Class 8.8/Class 8 and beneath; and utilize 300 HV washers for Class 10.9 screws/screws and Class 10 nuts and underneath—they are not appropriate for use with Class 12.9/Class 12 clasp.
DIN 125A Washers are recorded by their ostensible opening size, which shows screw size, so on the off chance that you have a M10 screw select a M10 washer. Flat Washers might be equivalent to ISO 7089. DIN 433 is a more modest OD and DIN 9021 is a bigger OD washer contrasted with DIN 125 A.
