Thread Inspection

Thread rolled parts may often be small in size, but the impact they have is large. Since threading is depended upon to fasten together countless pieces of equipment and machinery, it is crucial that thread rolled parts undergo thorough thread inspections to ensure that each piece meets stringent quality standards.

Thread Inspection Gaging

As mentioned above, adhering to high standards of quality is a necessity when producing thread rolled parts, and thread inspection is part of that quality control process. So, what does thread inspection entail? At the basic level, thread inspection involves two simple methods of gaging thread rolling quality and success: Gaging with Thread Plugs and Gaging with Thread Rings. Ring gages and thread plugs are manufactured per ANSI/ASME B1.2.

Thread Rings

Adjustable thread ring gages are inspection tools used during thread rolling projects. cylindrical ring with an inside diameter that is finished to gage the tolerance of a thread rolled part. By providing a fixed limit to gage by, thread rings allow manufacturers to precisely measure the tolerances of thread rolled parts.

Thread Plugs

Thread plug gages are also used to check tolerances of threaded parts according to a certain specification. These thread rolling inspection tools ensure that the manufactured parts conform to the precise standards that they are required to meet.
