Teclock dial indicators

 

 

Very few Teclock gages are currently available. If you're looking for anything other than the most common indicators shown on this page you're probably out of luck. The only Teclock distributors in the USA are the major catalog houses such as MSC, J&L, and Travers. In Canada it's Thomas Skinner & Son. If your tool isn't in their catalog, it isn't available .

There is little or no customer support in the US for any Teclock gage and spare parts are nearly impossible to obtain (no one stocks them).

We usually suggest to our customers that they buy equivalent models made by Mitutoyo or Brown & Sharpe when it comes time to replace an old or damaged Teclock gage. This way they'll have reliable customer support, repair service and spare parts for years to come. Replacement suggestions are made at the bottom of this page.

That said, here's what's currently available :

Teclock model AI-921B (left, with black dial) and model AI-921 (right, with white dial)
 

Teclock has been the manufacturer of a wide variety of precision gages for over 50 years. The accuracy of these made-in-Japan dial indicators is comparable to European-made gages even if the workmanship and durability are lacking. The economical prices of these gages make them ideal for short runs or as throw-aways. If damaged, you may have no other option but to replace them. Teclock models are usually not repairable.

All inch models (AI) use imperial 4-48 thread contact points and have 3/8" diameter stems.
Metric models (KM,TM) use metric M2.5 thread contact points and have 8mm diameter stems.

 

AGD Group 2

(dial diameter approx. 2.2") includes lug mount back. A bezel clamp and two tolerance markers are provided which you must install yourself. Model AI-921B features a black dial while model AI-921, by far the most popular, has a white dial and shock-proof movement. Model AI-922 is the same as AI-921 but it has a balanced 0-50-0 dial. Model AI-921N contains unreliable plastic parts and is discontinued. You'll want to replace it with AI-921 which has all metal components.

Teclock indicators are often disguised with vanity dials such as SPI. Some of the models offered below will have the SPI logo on the dial. Other than the name, the indicators are identical.

Note: replacement indicators for Teclock dial bore gages are not available at this time. Other manufacturers' indicators will not fit the Teclock bore gages. We strongly urge you to think twice before investing in Teclock dial bore gages.

AGD Group 1 - small dial face

 

Small dial diameter approx. 1.6" includes lug mount back. This inch model has a bezel lock. Teclock indicators are not very good and unless the guys upstairs absolutely insist on this model, you'll fare better by investing in the best AGD-1 indicators available on page 6.

Teclock test indicator

 

These Teclock test indicators are available with SPI vanity dials. What is a vanity dial? SPI has arranged to put its own name on the dial. The indicators are identical in every other respect.

Be advised that, in most cases, repairs will not be possible because of the lack of internal spare parts. Compare these models to other manufacturers.

Tecock dial thickness gages

 

Thickness gages (also called thickness micrometer) are used for quick and accurate measurement of sheet metal, paper, plastic, mouse ears and other body parts (don't ask why), leather for purses, and gut strings for the Renaissance lute* among other, more mundane applications.

Frequently sold with the SPI, Fowler and other names on the dial. These full-sized Teclock thickness gages have a lifting lever on top allowing for easy, one-handed operation. The large dial diameter is 2.16" and the flat measuring face (anvil) .394" in diameter, is ceramic. See measuring force below. Made in Japan.

 

Teclock model SI-112 shown above, with the SPI name on the dial

To place an order for these, or other thickness gages, please proceed to page 12.

Parts for repairs will not be available for these Teclock models. If you require convex or ball-shaped anvils, consider Kafer dial thickness gages. See our page devoted to dial thickness gages for further information and other options including metric models.

 

 

 

 

 

Tecock replacement models

 

Since many Teclock indicators are not available in the US, it’s an easy matter to replace them with other manufacturers’ indicators. They’re all AGD conforming, so dimensionally they’re interchangeable. The only time they can’t be switched is if there is a special indicator back such as a sliding back. If it’s a regular lug back, however, there’s no problem. Here are some common Teclock models (which are not readily available) and their equivalents.
