1.1本规范规定了用于制造机械紧固件（包括:螺栓、螺母、铆钉、螺钉、垫圈和冷制造的特殊零件）的碳和合金钢丝、棒材和盘条的物理、机械和冶金要求的质量保证要求。 笔记 1-钢铁行业使用该术语 “ 质量 ” 指定材料的特性，使其特别适合特定制造和/或应用，并不意味着 “ 质量 ” 在通常意义上。 1.2导线尺寸范围包括0.062至1.375英寸。 1.3杆尺寸范围通常包括 7. / 32 在里面（0.219）至 47 / 64 在里面（0.734），通常在 1. / 64 增量（0.0156）。 1.4钢筋尺寸范围包括 3. / 8. 在里面（0.375）至1 ½ 在里面(1.500). 1.5超出第1.2-1.4段范围的线材、棒材和棒材的尺寸可通过买方和供应商之间的协议订购。 1.6材料在许多应用变体中提供。买方应酌情就制造过程和成品应用向供应商提出建议。五种应用变化是: 冷镦 凹头 内六角头 无屑螺母 管状铆钉 1.6.1为所有五种应用变化提供电线。 1.6.2杆和棒应提供给单一应用变体；冷镦。

1.1 This specification establishes quality assurance requirements for the physical, mechanical, and metallurgical requirements for carbon and alloy steel wire, rods, and bars in coils intended for the manufacture of mechanical fasteners which includes: bolts, nuts, rivets, screws, washers, and special parts manufactured cold. Note 1—The Steel Industry uses the term “ quality ” to designate characteristics of a material which make it particularly well suited to a specific fabrication and/or application and does not imply “ quality ” in the usual sense. 1.2 Wire size range includes 0.062 to 1.375 in. 1.3 Rod size range usually includes 7 / 32 in. (0.219) to 47 / 64 in. (0.734) and generally offered in 1 / 64 increments (0.0156). 1.4 Bar size range includes 3 / 8 in. (0.375) to 1 ½ in. (1.500). 1.5 Sizes for wire, rod and bar outside the ranges of paragraphs 1.2-1.4 may be ordered by agreement between purchaser and supplier. 1.6 Material is furnished in many application variations. The purchaser should advise the supplier regarding the manufacturing process and finished product application as appropriate. Five application variations are: Cold Heading Recessed Head Socket Head Scrapless Nut Tubular Rivet 1.6.1 Wire is furnished for all five application variations. 1.6.2 Rod and bar are furnished to the single application variation; Cold Heading.
