ASTM A108 Specification

Forgings, Fasteners, Boltings, Stud Bolts, Screws, Nuts


ASTM A108 specification covers cold-finished carbon and alloy steel bars produced in straight length and coil. Cold-finished bars are suitable for heat treatment, for machining into components, or for use in the as-finished condition as shafting, or in constructional applications, or for other similar purposes (Note 1). Grades of steel are identified by grade numbers or by chemical composition.
NOTE 1—A guide for the selection of steel bars is contained in Practice A400.
Some end uses may require one or more of the available designations shown under Supplementary Requirements. Supplementary requirements shall apply only when specified individually by the purchaser.
