INTERNAL GROOVE MICROMETERS ● Smooth friction thimble ● Lock screw ● Satin chrome reading surface Measure grooves for retaining rings and “O” rings, oil grooves, washer grooves, as well as bores and recesses. Depth of grooves up to 5/64” can be measured with 701A; and 7/32” with 701B. Tool is accurate to ±.0002” ● Hardened and ground gaging contacts are .030” thick ● Contacts have flush ends to gage grooves at the bottom of blind holes. BALL ATTACHMENT FOR OUTSIDE MICROMETER CALIPERS No. 247 Series Snaps on anvil of regular micrometers for measuring wall thickness of tubing, bearings, sleeves, etc. Ball is hardened and moves freely in retainer. The diameter (.200” English - 5 mm metric) of each ball used must be subtracted from micrometer readings. For checking out-of-roundness in centerless grinding and other machining operations; also for measuring odd-fluted taps, end mills, reamers. Direct reading. Carbide facings on spindle and anvils. Anvils match index of cutter teeth. ● Satin chrome finish ● Carbide faces TUBE SCREW THREAD SHEET METAL V-ANVIL GROOVE MICROMETER CALIPERS MICROMETER CALIPERS MICROMETER CALIPERS MICROMETER CALIPERS MICROMETER No. 569 Series No. 222 Series Highly useful for measuring wall thickness of tubing, cylinders or from a hole to an edge. Has “half” frame and extended anvil at right angles to spindle. Frame has smooth black enamel, and sleeve and thimble Satin Chrome finish. One-piece spindle with threads hardened, ground from the solid and stabilized. Special anvils also can be furnished - prices on application. Available with attractive, protective case, sent without case unless otherwise ordered. Packed one in a box. Widths of either internal or external grooves and lands can be quickly measured with the new Starrett No. 260 Groove Micrometer. Graduated in .001”and has a reach of 1.5/8” max. hole depth. Will measure groove widths from .050” to 1.050” and land widths from 0 to 1.000”. Each measuring disc is 9/32” O.D., .025” thick and hardened, ground and lapped. Satin Chrome finish with quick reading, staggered graduations. With ratchet stop. Rep. Rod 1-STR-18479 * Add .050” to micrometer reading. Furnished in attractive, protective case. HUB MICROMETERS Ideal for measuring hub thickness, insert through small holes to measure thickness, etc. Special shallow frame passes through 3/4” hole. Satin chrome finish, mirror lapped anvil and spindle faces, hardened spindle with threads ground from solid. Available with attractive, protective case. Sent without case unless otherwise ordered. Available with attractive, protective case. Sent without case unless otherwise ordered. Packed one in a box. No. 575, No. 585 Series No. 483 (for 3 flute), No. 485 Series (for 5 flute) These micrometers have a pointed spindle and a double V-anvil, both shaped to contact the screw thread at the pitch diameter. The micrometer reading therefore gives the true pitch diameter which equals the outside diameter of the screw minus the depth of one thread. Frames are one-piece drop-forged steel with no-glare satin chrome finish all over. One-piece hardened spindle with threads ground from the solid. Furnished with fixed (non-rotating) anvil and without ratchet stop or lock nut. These micrometers reach over the edge of sheet metal and take measurements away from the edge toward the center. Also for other gaging jobs where a deep throat micrometer is needed. Rounded anvil on 1” size gives a point contact for more accurate gaging; flat anvil also available. 1/2” and 13 mm micrometers have full finish frames; 1” and 25 mm micrometer frames have black wrinkle finish. Available with attractive, protective case. Sent without case unless otherwise ordered.
