Fowler 52-437-250-0 9-Pair 18pc 1/4x3/4-1-3/4x6in Steel Parallel Set

The Fowler 52-437-250-0 is an 18-piece (9-pair) alloy steel parallel set designed for precision workholding and setup on milling machines, surface grinders, and drill presses. Each parallel measures 1/4 in. thick x 6 in. long, with heights ranging from 3/4 in. to 1-3/4 in. in 1/8 in. increments (3/4, 7/8, 1, 1-1/8, 1-1/4, 1-3/8, 1-1/2, 1-5/8, 1-3/4 in.), as confirmed by the size markings visible on the tray in the photos. The alloy steel construction is hardened to 52–58 HRC and ground on all four sides for flatness and parallelism, enabling accurate, repeatable workpiece elevation and squaring in vise setups. Each parallel features two through-holes for easy magnetic retrieval from a vise. This set is listed as New — other condition and ships in the original plastic molded case with individual labeled slots for organized storage and quick size identification.
