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

Specification

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.
