M10 Din 9021 Washer Metal Extra Large Diameter Flat Washers Round Square
DIN 125 / DIN 9021 Flat Washers made of steel, galvanized according to DIN 125 / DIN 9021 from China Flat Washer, Fender Washer Manufacturer
Description
Flat Washers are a thin, flat, circular steel part with a centrally located hole. Washers are designed for assembly around a bolt or screw, between the bearing surface of the fastener and the part to which it is attached. Flat washers are used to improve stress distribution and to span large clearance holes. Grade 8 through hardened flat washers are dimensionally similar to their USS washer counterparts, but with tighter tolerances on thickness, and manufactured from a higher grade of steel. They are to be used specifically with high-strength hardened steel bolts.
Extra heavy duty flat washers are available from Mutual Screw & Supply. As a dependable distributor of fastener products since 1947, we can supply you with thick washers and standard sized units. Large washers machined for heavy-duty applications can give you the extra strength needed for tight and secure fittings.
We offer hot dipped galvanized, extra heavy SAE flat, plain finish dock, zinc yellow extra heavy SAE flat, and zinc yellow plated steel through-hardened heavy duty extra-thick SAE flat washers.
Flat Washers In A Wide Range Of Sizes And Materials
Flat washers are an essential part of any fastener assembly. As
they serve to incorporate spacing and distribute load when placed
between a nut and bolt or screw they willhelp prevent wear and
distortion of installation surfaces over time. Use them to make
maintenance easier by allowing for smoother oosening and tightening
ofcomponents We manufacture flat washers in a wide range of
materials and in an extensive range of shapes. sizes and
thicknesses. They can be ordered from our inventory

Flat Washers
Flat washers are used under bolt heads or nuts to increase the bearing surface area, or to offer protection so that the nut or bolt can be rotated without distortion of the bearing surface.
Flat Washer Types
ASTM F844 USS (United States Standard) Flat Washers
USS flat washers were developed to satisfy engineering requirements in the majority of industrial applications in all fields of manufacturing, maintenance and repair. The Outer Diameter (OD), Inner Diameter (ID) and Thickness (Th) specifications were developed to meet the broadest possible number of applications.
SAE (Society of Automotive Engineers) Flat Washers
SAE flat washers were developed and specified by the Society of Automotive Engineers to meet the requirements of automotive manufacturer applications as broadly as possible. They feature smaller outside diameter when compared with USS washers.
