1.1 Scope
1.1.1 This Standard covers the complete general and dimensional data for five products in the inch series recognized asan American National Standard.These five structural products include(a) heavy hex structural bolts: ASTM F3125/F3125M(b)heavy hex nuts: ASTM A563 and ASTM A194/A194M(c) hardened steel washers – circular, circular clipped, and beveled: ASTM F436/F436M(d) compressible washer-type direct tension indicators: ASTM F959/F959M(e) twist-off-type structural bolts – heavy hex and round: ASTM F3125/F3125M
1.12 The inclusion of dimensional data in this Standard is not intended to implvy that all products described herein arestock production sizes. Consumers should consult with suppliers concerning lists of available stock production sizes.
1.2 DimensionsAll dimensions in this Standard are in inches, unless stated otherwise, and apply to an unplated or uncoated productWhen plating or coating is specified, the finished product dimensions shall be as agreed upon between supplier andpurchaser. Symbols specifying geometric characteristics are in accord with ASME Y14.5.
1.3 OptionsOptions, where specified, shall be at the discretion of the supplier, unless otherwise agreed upon by the purchaser with themanufacturer or distributor.
