#12 Countersunk Finishing Washer - .307/.267" I.D. - Steel - Nickel Plated - Grade 2 - 100 Pk

Spring Washers Are Formed In An Irregular Shape To Provide Lighter Resistance And Distribute Pressure In Low Strength Fastening. Spring Washers compress to act like a spring and deflect when loaded, providing a preload between the two joined surfaces. Fasteners are used where assemblies need a part to eliminate rattle, maintain assembly tension, compensate for expansion or contraction, or to absorb intermittent shock loads for long lasting durability.

External Tooth Lock Washers secure bolt heads or nuts to increase the bearing area and offer greater hardness so that the nut or bolt can be rotated without distortion of the bearing surface. Hardware is constructed of high quality steel for long lasting durability.

GN 184 countersunk washers are retained to the face of the shaft end with countersunk screws, forming a clean-look end cap. Screw size is M5.. Height is 1/8".

DIN 6319 spherical washers are used for clamping on non-parallel surfaces. These are sold individually not as sets. Refer to spec sheet for corresponding spherical washer selection.

Square Beveled Washers are commonly used to provide a parallel bearing surface when fastening bolts through the flanges of I-beams in structural applications.
