Our Latest products

A Thread ring GO gage checks the maximum minor diameter and the maximum pitch diameter size in a part, the NOGO checks for the part not to exceed the minimum pitch diameter size on a part. All GSG Thread Ring Gages are manufactured to ASME/ANSI B1.2 or B1.16M. Each thread ring gage is made of oil hardened Tools Steel.

reverse plug gage

•The Reversible plug gage has the advantage that it can be reversed and used at the opposite end when one end becomes worn and goes out of tolerance.
•The gaging members are simple pins that can be removed from the handle by loosening the collet nuts at the ends.
•Each end of the handle is color coded, green for Go and red for No-Go.
Depth steps are available upon request.
•Available in Steel, Carbide and Chrome.
•Extra long members available.
•Gaging surfaces are hardened to Rc 58-62.

taper plug gage

•The Taperlock gage is named because of the tapered shank, which locks into the tapered hole in the end of the handle.
•Used for gages up to 1 ½ inches.
•As a further aid in identification, the Go and No-Go members have a different length of gaging surface. It is permissible to make the No-Go gage shorter because it is not supposed to enter the part.
•Depth stops are available upon request.
•Available in Steel, Carbide and Chrome.
•Gaging surfaces are hardened to Rc 58-62.

trilock plug gage

•The Trilock design has been found best suited for gages between 1½ and 8 inches in diameter.
•The Trilock feature is the source for the name of this design. The handle has three prongs on the ends, which fit into three grooves equally spaced around the central hole of the gage members.
•A bolt holds the member to the handle and the Trilock grooves and prongs stabilize the member.
•Like the pin (reversible) type, Trilocks are reversible, since either face can be locked to the handle.
•Available in Steel, Carbide and Chrome.
•Gaging surfaces are hardened to Rc 58-62.

progressive lock gage

•In some special cases, a little gaging time can be saved by putting the Go and No-Go diameters on a single gage member.
•A progressive plug, for example, is suitable for checking a short hole, which is open at both ends.
•Obviously, the hole cannot be deeper than the Go section of the plug.
