Fowler #52-401-204-1, Outside Micrometer, 12-16", 0.001"

The Fowler 52-401-204-1 is a large-range interchangeable anvil outside micrometer covering 12 to 16 inches in one-inch increments. Made in Japan, the tool features Fowler's signature hammertone blue baked enamel frame and is supplied complete with interchangeable anvils, setting standards for each inch of range, a wrench, and a fitted hardwood case. Graduation is 0.001 inch on a satin chrome sleeve, with microfine markings for clear readability. The spindle thread is hardened and precision ground with a microlap finish, and measuring faces are carbide tipped for wear resistance. A positive lever locking clamp maintains accurate settings, and the ratchet stop ensures consistent measuring force for repeatable readings. The tapered bushing design on the interchangeable anvils allows rapid and precise anvil changes without tools. Each anvil includes an adjusting collar to set the overall measurement dimension accurately. This micrometer is suited to machine shops, tool rooms, inspection departments, and production environments where large-diameter workpieces require precise outside dimension measurement across a wide range without purchasing multiple individual micrometers. Part number 52-401-204-1 corresponds to the 12-16 inch model in Fowler's 52-401 interchangeable anvil series. The fitted wooden case includes dedicated slots for each anvil, standard, and wrench, keeping the complete set organized and protected during storage and transport.
