I currently have several dial indicators for sale, including Starrett, Mitutoyo, Brown & Sharpe, Interapid, Federal, and others. If interested in multiple items, I DO COMBINE SHIPPING, and charge only what it costs to ship the item(s), whether it's for one item or ten. Consequently, the total shipping cost for multiple items will often be very similar to (and sometimes the same as, especially in the case of fixed-rate shipping) the cost for a single item.

Federal B3K .00025”, .040” dial indicator, made in USA, in excellent condition. Indicator functions perfectly: plunge is smooth, crisp, and responsive throughout its travel. AGD Group 1 gage (a bit smaller than the typical, 2” Group 2 indicator) with 1-1/2”-diameter case and 3/8” stem diameter. Features a balanced-reading dial to 10 and “adjustable” back. Measuring range of 0–.040” with .00025” graduations. What you give up in measuring range you gain in precision and reliability. A classic Federal gage in fine condition for the finest measurements, and very ruggedly built.

Please note, the machinists clamp being used to prop up the indicator in certain of the photos is NOT included in the auction.


If you have any questions don’t hesitate to contact me. I’ve tried to take photos showing the item as a whole and in detail from every angle, but if you’d like to see something in better detail or if I’ve left out something that you want to see, just let me know.

Potential international bidders: please contact me BEFORE bidding for an accurate shipping quote. Item(s) will ship USPS First Class or Priority, at cost, unless you have other shipping preferences. I always combine shipping and I do not charge more for shipping than it actually costs. I will, by default, find and use the cheapest USPS Priority option, whether it’s flat rate or by weight/distance. The eBay shipping calculator is usually relatively accurate, but if you have any questions or uncertainties about shipping cost, please contact me for a conclusive shipping rate.
