Both attachments have a .375” (9.5 mm) diameter hole to fit all indicators made to AGD standards and can be securely clamped to the indicator stem. The ball end on the swivel arm which contacts the work is 1/8” (3 mm) in diameter. Backs with adjustable Mounting Bracket No. 674 Series For use with gages and gaging fixtures where an adjustable indicator mounting is required. A dovetail with rack and pinion adjustment provides 1.1/8” (28 mm) indicator travel. A 1/8” hex wrench is used to adjust and lock the indicator in final position. The bracket has two counterbored mounting holes (for 1/4” socket head screws), and the back has four screw holes so the indicator back can be rotated. Magnetic Backs No. 676 Series These magnetic backs provide a quick and easy means of attaching any Starrett AGD indicator to flat, ferrous metal surfaces. A real time saver for machine, jig and fixture set up. Requires no clamps, rods or snugs. A special 5/16”-24 threaded stud back is provided to replace the standard lug back. The powerful, permanent magnet is then attached to the threaded stud. Anti-magnet indicators are not required. Universal Backs No. 672 Series Featuring a universal ball joint attached to the end of a gooseneck shank, these attachments make it possible to position an AGD indicator at any desired setting. The indicator can be rotated 360° and angularly up to 90° and locked in the desired position by tightening a single knurled nut. Straight shank is 3/8” (9.5 mm) in diameter. Lever Control Fits only indicators with a case stem cap. No. PT99356 PART# 1-STR-72088 Handy attachment mounts in place of the stem cap and is interchangeable on most Starrett Series No.'s 81, 25, 2600, 655 and 656 AGD Indicators up to 1” or 25 mm range. Pressing down the lever lifts the spindle; releasing it lets the spindle contact the work. Easy to install in the left or right hand position using a screwdriver and an open end wrench. If ordered on a new indicator, specify left or right hand position. (Furnished at left unless otherwise ordered.) NOTE: .500”, 1.000”, 10 mm or 25 mm indicators must be originally ordered with case stem cap to be used with cam type lifting levers. No extra charge for case stem cap. Long Stem Dial Indicators Range Limit Cap No. 25LC PART# 1-STR-50152 NO. 80 Series MINIATURE DIAL INDICATORS 1.17/64” Diameter, 7/32” Stem Equipped with high precision, low friction movements, all with frictionally adjustable bezels for quick, positive zero setting. No glare, white eggshell finish dials. Black bezel, silver finish on case. Furnished with balanced dial, jeweled bearings and lug-on-center back. Universal Attachment No. 671 This Universal Attachment is for use with indicators having standard AGD.375”(9.6 mm) stem diameters. It clamps on the indicator stem and its movement is transmitted through the contact point to the indicator. Furnished with two interchangeable arms, one straight for measuring internal surfaces and one angular for measuring at right angles to the indicator spindle. Depth Gage Bases with Stem Collet No. 648 Series Bases are for mounting AGD indicators to measure depths. Indicators with .375” (9 mm) stems will fit the stem collet furnished with the base (No. 25SC38). Indicators with 8 mm stems need the split bushing No. 25MSB to adapt to the stem collet. Longer contacts or extensions may be required. Split Collets No. 25 SC Series English and Metric Threads For mounting AGD indicators with 3/8” (9.5 mm) or 8 mm stems in gaging and work location fixtures, these collets simplify fixture mounting. Screw the collet into the fixture or into our No. 648 Depth Gage Base, insert the indicator into the collet and tighten it in place with the hexagonal nut. Internal collet fingers grip the stem with equal pressure to eliminate spindle binding. Made of steel with black finish. Overall length of collet and threads is 1”. Starrett No.s 81, 25, 2600, 655, and 656 Indicators through the 1” (25 mm) range can be furnished with long stems up to 12" (300 mm). These are especially useful for gaging in deep holes or where obstructions prevent the use of regular indicators. Specify stem length from outside case diameter when ordering. NOTE: Long stems not available on No. 80 Series Miniature Dial Indicators The Range Limit Cap replaces the stem cap furnished on most Starrett Series Nos. 81, 25, 2600, 655 and 656 AGD Indicators, preventing the possible error of a complete revolution. It can be adjusted to limit an indicator’s measuring range any amount up to 3/8” (9.5 mm). Split Bushings Split bushings fit over the indicator stem to increase the overall diameter for mounting in fixtures. No. 80-114J No. 80-134 No. 80-144J CATALOG NO.
