In fact, both attributes are applied to all of our products, including our other washers, shims, spacers, metal discs, and lock plates. The tight tolerances we can offer for our precision thrust washers are: Flatness: 0.001 inches (0.025 mm) Parallelism: 0.001 inches (0.025 mm) Thickness: +/- 0.0004 inches (0.010 mm)

The only slight possible difference is that there is a manufacturing tolerance allowance of 1mm above or below the dimension stated in the form table. The thickness of the washer should not vary away from the thickness stated in the table because all washers are made from standard sheets of metal that are themselves standardised in thickness.

Choose these washers for their adherence to strict military standards for material and construction. 18-8 stainless steel and 321 stainless steel washers have excellent corrosion resistance in most environments. They may be mildly magnetic. Passivated 18-8 stainless steel washers have added protection against oxidation and corrosion.

Flat Washer Thickness Table Steel Gage Thicknesses The Flat Washer Gage Thickness/Plain Washer Gage Thickness Table displays standardized steel thicknesses for standard flat washers (also known as plain washers). Washers are manufactured from Strip & Tube steels. Gage Numbers are standardized strip/tube steel thicknesses.

Flat and nominally marked shims have a very severe impact on alignment costs. Along with a very tight flatness specification the material used to produce ALOMA quality shims must meet the following thickness tolerances: All of Aloma Shims greater than .050 are marked with the exact thickness to within .0005" .

Spring washer dimensions are adapted to work with screw metrics. The standard defines the proportions for a washer with regard to thickness, height, and external diameter, for each specific metric. Tolerances in the thickness of a piece is specified by DIN1544 for pieces which are <= 6 mm thick and by DIN1543 for pieces which are > 6 mm thick.

Choose from our selection of precision washers, including ring shims, shims for shortening screw shoulders, and more. In stock and ready to ship. Remove layers with a utility knife until you get the thickness you need. Also called tolerance rings, these rings are for use in stamped, molded, or worn housings to form a tight hold on the

grip length of the joint (minimum thickness of materials which can be clamped) excluding the washer thickness. Thread Length Thread length is the length from the extreme point of the bolt or screw to the last complete (full form) thread. For bolts and screws in this standard, other than lag screws, the Nominal Thread Length (L T

There is a tolerance of about 1-1.5mm on the thickness of the washers produced. This variation is because the punched washers are made on punched presses. The
