Industrial washers are fastening components installed beneath a bolt head or nut to distribute bearing load, protect the joint surface and support the intended behavior of a bolted joint. The correct washer must be selected according to its standard, nominal size, dimensions, material, finish and service conditions.

Types of industrial washers

The TTBOLT washer catalog is organized into flat or plain washers, regular helical spring-lock washers and other specialty washer families as they are added. Each washer form is placed in a separate subcategory so that different dimensional standards and product types are not mixed.

Industrial washer selection guide

Before ordering, check the applicable dimensional standard, nominal size, inside diameter, outside diameter, thickness, material grade, hardness and coating. For electroplated high-carbon spring washers, hydrogen-embrittlement controls may be required. The word “lock” in a washer name does not by itself guarantee permanent locking; joint preload, vibration and operating conditions must also be evaluated.
