3/4" Flat Washer - SAE - Extra Thick - 13/16" I.D. - Steel - Yellow Zinc - Grade 8 - Pkg of 25

Case hardened steel with black oxide finish. Extra thick for increased strength.

Hard Steel Flat Washers are used to increase the surface area of fasteners in order to more evenly distribute the force applied when fasteners are tightened to a surface. They are intended to be used in conjunction with Grade 5 and Grade 8 bolts and nuts. Common applications for hard steel washers include industrial, MRO, manufacturing and oil & gas. Features: Hard Alloy Corrosion Resistant Industrial Strength

Solid Brass Flat Washers are used to increase the surface area of fasteners in order to more evenly distribute the force applied when fasteners are tightened 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. Brass Flat Washer are manufactured from solid brass to protect against tarnishing and corrosion and are a commonly used washer in the plumbing, heating & air, and electrical trades. Features: Solid Brass Corrosion Resistance Vibration Resistance Acts as Spacer

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 steel and zinc-plated and are manufactured to ASME B18.21.1 standard. Features: Vibration Resistance Acts as Spacer Increases Surface Area Unhardened Carbon Steel

Silicon Bronze 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. Silicon bronze will not corrode, and has better strength and temperature resistance than brass, making it the superior choice for marine applications. They are intended to be used with silicon bronze nuts and bolts in non-critical applications and are manufactured to the ASME B18.21.1 standard. Features: ...
