Go & No-Go FIXED LIMIT GAUGES For many years Go & No-Go Fixed Limit Gauges have been a vital part of maintaining tolerances of the highest standard and have been at the core of quality control applications for a variety of end-user applications. Fixed Limit Gauges provide an accurate, quick, easy to use and economical solution of the inspection of work pieces, giving a pass (Go) or fail (No-Go) result.

Why Reversible? YPG Reversible Gauges can have up to twice the useful life compared to non-reversible types because most of the wear in use occurs as the gauge is presented to a hole. With reversible gauges, the gauging member can simply be removed from its handle, reversed and refitted presenting a fresh, unworn gauge end.

How to specify your plug gauge requirements. For plain plug gauge requirements (i.e. to check a single diameter) you only have to specify the hole size and work piece tolerance. From this information we calculate the required gauge tolerances according to a standard appropriate to you. In the UK, gauge tolerances are normally

For deep bores it may be necessary to specify also the protrusion required (i.e. the working length of gauge protruding from the handle). For gauge sizes up to 19.45mm (No Go end) Wire Type Reversible gauges will be provided. Larger sizes will be supplied as Trilock Reversible gauges, unless the Taperlock design is requested.

required in accordance with BS969: 1982. This British standard specifies the tolerances and limits for cylindrical plain plug, ring and gap gauges. Gauges can however be manufactured to any recognized national standard (DIN, NFE, AGD, TDS, ISO, JIS, ANSI/ASME).

Optional Pin & Plug Gauge Features. Pin, Tri-Lock and Taper-lock gauges have a number of features which can be added to suit a particular application. YPG’s experienced, specialist gauge makers have considerable experience in applying these features against the customer’s component drawing requirements.

• Extended length gauge members.

• Pilot Entry lead-in chamfers.

• Progressive (Stepped) gauge member, Go, No Go.

• Leading face on Go member relieved to clear a protrusion.

• Progressive (Stepped) gauge member for inspecting concentricity.

• Extended length handles.

• Segmented (Blade) No Go gauge member for checking out of roundness. • Hexagonal gauge members. • Air Release flat. • Depth steps.

Fine Tolerance Additions. If the work piece tolerance is a very tight manufacturing tolerance when standards such as BS 969:1982 are applied an additional charge will be incurred. If the work piece tolerance is tighter than 0.009mm, we would recommend an Indicating Bore gauge be used.
