taperlock

Taperlock Thread Plug gages provide a functional check of internal threads.  They are made from an oil hardening tool steel in full conformance to ANSI B1.2 & B1.16M.  Thread work plugs are taperlock design up to 1 1/2" (38.1mm).  Sizes larger than 1 1/2" are trilock design.  Chip grooves are provided on all GO work Plug members in sizes #10 and larger.  Chip grooves, also called dirt grooves, are located at the entering end of the gage.  They provide a means of cleaning the dirt and other debris from the internal product thread.

truncated

Truncated Setting Plug gages provide an accurate control in checking or setting thread ring gages.  They are made from an oil hardening tool steel in full conformance to American Gage Design standards B47.1 and to ANSI B1.2 & B1.16M.  They are held to Class "W" tolerances on lead, flank angles, and staitness (taper)  and are available in Class "X" or "W" tolerance in pitch diameter.  Truncated set plugs have a common pitch diameter the full thread length.  The front, or truncated portion of the major diameter is truncated for one half the length.  The rear portion, is full form.  The ring gage is set first to the truncated portion noting the feel or fit.  The ring is then advanced onto the full form portion.  If the full form portion will not accept the ring gage, or the ring gage becomes tight and difficult to turn, there could be a flank angle deviation or interference at the major diameter.

reversible 

The design of the reversible thread plug permits the members to be reversed end for end, in the handle, resulting in double wear life.  Chip grooves are standard on both ends of the GO member in sizes #10 and larger.

The roots of Glastonbury-Southern Gage began in 1962 when Glastonbury gage opened as a manufacturer of plain cylindrical plug and ring gages serving the aircraft, aerospace and automotive markets. Known for their reputation to produce to very exacting tolerance requirements, the company grew quickly to become the premier manufacturer of fixed limit gages, Part Master gages and special shapes masters in the USA. Wishing to continue their growth with quality products and services, Glastonbury Gage purchased the assets of the Southern Gage, the leading thread gage maker, in 1995. Founded in 1954, Southern Gage leads the industry with quality products and innovation. Southern Gage built their quality reputation by producing the highest quality thread gaging products and the ability to manufacture all types of gage products for both internal and external gaging applications. As a result of combining Southern Gage manufacturers a complete line of variable lint gaging systems, zero spindle fixture gaging systems and electronic comparator systems. The newest product offerings include”Hi-Lo” style setting masters, BSP “full form” British standard pipe thread gages, API gages and special service such as “Redline Delivery”… When you need it fast! Glastonbury-Southern Gage continues to serve the automotive, aerospace, medical, off-road equipment, diesel engine, valve manufacturing, nuclear, fastener and industrial distribution industries. Glastonbury-Southern Gage is positioned to serve industry’s gaging requirements into the twenty-first century.
