1/4" Spherical Washer Set - 5/8" O.D. - 3/16" Thick - Stainless Steel - SP-0SS

Self drilling screws have a point to cut through material and eliminate the need to drill a pilot hole. Indented hex washer head offers advantages of hex head, plus greater protection to mating surface.

Stainless Steel Fender Washers differ from Stainless Steel Flat Washers in that their outside diameters are much larger in proportion to their center holes. With this design a fender washer can be placed under the head of a bolt or nut to help distribute forces applied when tightening or to cover an oversized hole. Special Features: Load Bearing Surface, Corrosion Resistant, Chemical Resistant Applications: Corrosive Environments, Marine Applications, General Purpose

18-8 Stainless Steel Flat Washers are used to increase the surface area of fasteners, in order to evenly distribute the force applied when tightening them to a surface. They are also used to prevent loosening due to vibration, to stop the bolt or screw from pulling through, and act as spacers. They are manufactured from 18-8 stainless steel and are covered by the ASME B18.21.1 standard. Features: Load Bearing Surface Corrosion Resistant Chemical Resistant

Used in applications with nuts and bolts. The flat washer provides a greater bearing surface which helps prevent a nut or bolt head from tearing through the material. Flat washers are commonly used in decks and fence building.

Fender Washers are designed for use in auto body repair, sheet metal work, plumbing, and electrical applications requiring a large diameter for surface load reduction. Hardware is constructed of high quality steel for long lasting durability.
