1.1本指南旨在提供一种快速、易于使用的方法，用于确定委员会F-16紧固件规范及其适用的标记要求。根据产品类型（螺栓、螺母、垫圈等）和材料（合金钢、碳钢、不锈钢等）从下表中选择: 表号英寸公制黑色金属合金钢1 3碳钢1 3耐候钢1 3有色金属铝、铜2 3镍、钛不锈钢2 3其他涂层、定义、4 4试验方法、表面不连续性标记5 5 1.2表格尺寸限制和简单性要求禁止识别所有产品/材料组合的准确等级、类型、条件等。 在图纸上指定紧固件或订购前，必须审查产品规范，以正确、完整地识别紧固件及其可用变体。

1.1 This guide is intended to provide a rapid, easy to use method for identifying Committee F-16 fastener specifications and their applicable marking requirements. Selection is made by product type (bolts, nuts, washers, etc.) and material (alloy steel, carbon steel, stainless steel, etc.) from one of the following tables: Table Number Inch Metric Ferrous Metals Alloy Steel 1 3 Carbon Steel 1 3 Weathering Steel 1 3 Non Ferrous Aluminum, Copper 2 3 Nickel, Titanium Stainless Steels 2 3 Others Coatings, Definitions, 4 4 Test Methods, Surface Discontinuities Marking 5 5 1.2 Table size limitations and the need for simplicity prohibit identifying the exact grade, type, condition, etc., for all product/material combinations. The product specification must be reviewed prior to specifying fasteners on drawings or ordering to properly and completely identify the fastener, and its available variations.
