The 10% Rule is intended to assist in the selection of the tolerance for Go & No-Go gages. Combination go/no-go plug gauges Go plug gauges and no-go plug gauges are called single-ended gauges and consist of a handle into which a precisely machined pin or shaft has been inserted (sometimes called a member) and which is used to verify an aspect of the dimensional tolerances of the hole. a) Thread plug gauge (GO and NO-GO): A thread plug gauge is used to check acceptance of a “nut” – i.e. Since their invention at the turn of the century gauge blocks have been the major source of length standardization for industry. Tolerance Values Tolerance has parabolic relationship with the size of parts. Slater Tools has thousands of tools in operation throughout the world and has an excellent reputation for quality and service since 1951. Standard practice is to allow 5% of the hole tolerance for the GO gage and 5% for the NOGO gage tolerance. if the tolerance is applied minus on the Go , it is possible to accept product below the minimum stated diameter. Plug gauges are available in several different types. 4.00mm diameter to 300mm diameter. GO/NO GO Thread Plug Gauge GO/NO GO Thread Ring Gauge Model No. Use this utility to calculate the suggested Gage Tolerance and Go / No-Go gage dimensions. trailer .0002" = Class ZZ Tolerance per ASME B89.1.5 (See Tolerance Chart Below) GO Plug Gage =.250 +.0002" (Suggested) NO-GO Plug Gage =.254 -.0002" (Suggested) 0000000576 00000 n Master Gages Tolerance is split 50/50 Gage Maker's Tolerance Chart For Pin and Ring Gages 15150 25th Avenue North/Suite 200 sales@pqi.net www.pqi.net I happen to have a set of Forster .308 Win GO/NO-GO gauges,I believe they are labeled 1.630 and 1.634 respectively) that I use for setting the barrels on my Savage rifles in .308 Win.

Hexagon sockets in screws shall allow the GO member of the gage to enter freely to the minimum key engagement depths specified in the dimensional tables for the respective screw types. This calculator will determine the gage class and tolerance per ANSI ASME B89.1.5 for cylindrical I.D and O.D. PITCH DIA. Some financial calculators and computer programs can be used to calculate the yield to maturity. go =+ no go =– x lead tol. For plug gages a plus tolerance is applied to the GO member and a minus tolerance is applied to the No Go member. The lower image is a plain plug gauge used to check the size of a hole; the green end is the go, and the red end is the no-go. 0000005897 00000 n Yes we know there are exceptions to this statement. The premise is; if you surrender 10% of the total product tolerance to the gages, you will pass 90% of your product tolerance 100% of the time, if the Go fits and the No-Go does not. Tolerances, Engineering Design & Limits & Fits . Maximum Metal and Limit of shaft (high limit of shaft) = 37.98 mm “GO” gauge dimension become = 37.98mm Minimum Metal Limit of shaft (low limit of shaft) = 37.96 mm “NOT-GO” gauge dimension become = 37.96mm. 0000003228 00000 n These include: 1.

Using the maximum diameter of the hole as the No-Go and applying the tolerance MINUS insures that, if the No-Go plug does not enter the hole, the hole diameter is smaller than the maximum diameter of the hole and in tolerance. These gauges have a go gauge on one end, a no-go gauge on the other end, and a handle with bushings. Every part they are making that passes the 2A go plug, passes the 2A no-go plug, 100% scrap.
