Thread Gage Rotary
$850.00
The Thread Gage Rotary is a purpose-built cleaning and inspection fixture for API thread plug and ring gages ranging from 2 to 20 inches.
It keeps the gage supported horizontally on polyurethane-covered rollers, allowing technicians to smoothly rotate the gage while cleaning, deburring, buffing, sanding, and inspecting—without repeatedly picking it up, setting it down, and repositioning it by hand.
Originally developed around the demanding workflow of large API thread gages, the Thread Gage Rotary turns one of the most tedious jobs in a calibration lab into a simpler, more controlled process.

Built for the Work
Large thread gages can be heavy, awkward, and tedious to clean properly. Traditional handling means repeatedly lifting, rotating, setting down, and repositioning the gage throughout the cleaning and inspection process.
The Thread Gage Rotary was designed specifically to eliminate that unnecessary handling.
Place the gage on the rollers and leave it there.
Clean. Deburr. Buff. Sand. Inspect. Repeat.
The gage rotates smoothly while remaining supported, and the fixture can be repositioned to provide a better working or viewing angle when needed.
Designed for Thread Gage Maintenance
Well suited for laboratories and facilities working with large thread gages, including applications involving API 5B and API 7-2 plug and ring gages.
The adjustable roller positions allow the fixture to accommodate a wide range of gage sizes and geometries.
Heavy-Duty Construction
The Thread Gage Rotary was intentionally over-engineered for daily laboratory and industrial use.
Main Body: 0.187 in thick 304 stainless steel
Fasteners: Stainless-steel hardware secured with lock washers and nuts
Roller Tubes: 1.9 in diameter, 16-gauge galvanized steel
Roller Shafts: 7/16 in hex steel
Roller Covering: 1/8 in polyurethane sleeve
Roller Length: 10 in
Roller Weight: 2.4 lb each
Roller Rating: 270 lb each
Roller component ratings should not be interpreted as the rated working-load capacity of the complete fixture.
Adjustable for Different Gages
Roller position can be changed to accommodate plug and ring gages across a broad range of sizes.
The current design is intended for large thread-gage applications in approximately the 2 in to 20 in range, depending on the geometry of the individual gage.
If you are unsure whether a specific gage will fit, contact us before ordering and we will review the dimensions with you.
Smooth, Controlled Rotation
The polyurethane-covered rollers provide a durable contact surface while allowing the gage to rotate smoothly and predictably during cleaning and inspection.
The horizontal configuration keeps the gage supported throughout the process and reduces the repeated manual handling normally required to work around the complete thread surface.
Field Proven
The first Thread Gage Rotary has now been in service in a commercial calibration laboratory for more than one year.
After a year of real-world use:
The steel tube rollers continue to rotate smoothly
The polyurethane roller sleeves show no meaningful signs of wear
The fixture continues to perform as intended
We wanted real-world durability data before making durability claims. Now we have it.
Intended Applications
Ideal for:
Calibration laboratories
API thread-gage calibration
Thread-gage manufacturers
Dimensional inspection departments
Oilfield and OCTG facilities
Gage cleaning and maintenance stations
