Large Type B Standard Washer M21 A2 Stainless Steel
Pack 10 pcs.
Large thick washer for M21 bolts or 20mm axle tubes washers have been produced from A2 stainless steel supplied in a convenient pack size of 10 pcs.
These washers will probably be used as "axle spacers" in the DIY environment to prevent wheels from rubbing against adjacent parts, where the washer will provide improved rotational performance.
When used with large bolts then the importance of fitting washers under the bolt head and below a nut must not be underestimated as without washers being fitted full tightening strength cannot be achieved plus there is more likely to be resultant damage to the parent metal.
