Last Revision: 4/14/2016 Its name is derived from two tests: the check involves the workpiece having to pass one test (go) and fail the other (no-go).. For example, ISO 1502 sets a standard for screw threads and gauging to test them. The industry standard is referred to as the Ten Percent Rule. With tolerance XX we should be able to gain agreement between different calibration laboratories; however; the test method needs to be identical and the uncertainty needs to be ignored. pitch dia. With specified tolerance of GO and NOGO side, plug gauge is also known as pin gauge. rule: metric thread gages ansi / asme b1.13m, metric screw threads–m profile standard pitch diameter chart nominal size & pitch for external thread for internal thread pitch diameter go ring gage 6g tolerance pitch diameter not go ring gage 6g tolerance pitch diameter go plug gage 6h tolerance pitch diameter not go plug gage 6h tolerance mm in.

Meyer Gage tolerance calculator for plain cylindrical I.D. 10 Percent Rule results in gauge tolerance always being included in the part tolerance by up to 10%. Means, the tolerance on each gauge whether GO or NOT-Go is 1/10 of the work tolerance. Tolerance Class: 6g. min. Divide .0002” by 2 = .0001”. This rule results in the possibility that 10% of good product may fail inspection but that no bad product would ever pass inspection. This common rule of practice requires that 10% of the product tolerance is divided between the GO and NO GO gauges. Disclaimer: JavaScript seems to be disabled in your browser. x ±halfangletol. For example, if the work tolerance is 100 units, then the manufacturing gauge tolerance will become 10 units. The product has a tolerance of .002”. Thread Ring Gauge. It is difficult to get two calibration laboratories to return identical calibration results for tolerances XXX plain cylindrical gages. Ring Gauges receive the reverse tolerance direction so that the GO member is minus and the NO GO member is plus.

Uncertainty Determining Conformance to Specifications Grand Rapids, MI 49546-6937 The accepted method of establishing the gage tolerance is the 10% product tolerance rule. 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. There are two calculation options available, general engineering use or custom use. threads per inch major dia. Example for Thread Plug Gage: Plating of .0002" - .0003" allowance per side multiple x 4 .0003 x 4 = .0012" Max To calculate the gage tolerance using the 10% product tolerance Tolerance Direction Cylindrical Ring Gage Go Member is to the minus side, Nogo Member is to the plus side. The basic concept of a thread plug is to provide a quick inspection for machinists and quality inspectors to verify that the threads are within the accepted tolerance so that it interacts with the mating part correctly. max. UN thread calculator covers: - UN and UNR thread forms - Standard series of UNC, UNF, UNEF, UN-4, UN-6, UN-8, UN-12, UN-16, UN-20, UN-28 and UN-32. The “Go” ends of these working gauges have a wear allowance to DIN 7164.

The Go member would be specified as .4990” plus .0001” tolerance and the No Go would be specified as .5010”minus .0001”. A part has a hole diameter requirement of .500” +/- .001”. C) Adjustable Thread Ring Gauge (GO and NO-GO): These gauges, too, are ring shaped, but they have a split and an adjusting and locking screw facility to finely adjust their right gauging size. Thread gauges are typically used to check tapped holes in a component, which is a simple method for inspecting threads. The tightest tolerance for plain cylindrical gages which is feasible to be used to test parts is X. Tolerances XX and XXX plain cylindrical gages should not be used to test parts.
