QC/T 518-1999 汽车用螺纹紧固件紧固扭矩

本标准规定了汽车用螺纹直径6mm～20mm紧固件的紧固扭矩。 　　本标准适用于符合以下条件、以控制扭矩方式进行的紧固: 　　—外螺纹件的机械性能符合GB/T 3098.1规定的8.8、10.9级; 　　—内螺纹件的机械性能符合GB/T 3098.2或GB/T 3098.4，且具有充分发挥螺纹连接副承载能力的强度; 　　—螺纹符合GB/T 196，螺纹精度不低于GB/T 197规定的6级; 　　—内、外螺纹件的六角对边尺寸符合GB/T 3104规定的标准系列; 　　—内、外螺纹件的表面为汽车工业通常采用的状态; 　　—外螺纹件在紧固中承受轴向拉伸载荷。 　　本标准不适用于外螺纹件在紧固中承受压缩力的紧定螺钉、由外螺纹件攻击螺纹的自攻螺钉及木螺钉、采用弹簧垫圈或弹性垫圈的螺纹紧固件以及有效力矩型螺纹紧固件的紧固。 　　当表面状态不同、支承面尺寸及形态与标准条件差异较大，以致预紧力不能满足要求以及对预紧力有特别要求时，应对紧固扭矩进行调整。 　　注: 　　1 螺纹连接副的承载能力见GB/T 3098.2附录A。 　　2 有效力矩—在螺纹连接副不承受轴向载荷的情况下，平稳旋转螺栓或螺母时，测得的旋转力矩。

SAE J995-1999 钢螺帽的机械和材料要求

This SAE Standard covers the mechanical and material requirements for three grades of steel nuts suitable for use in automotive and related engineering applications, in sizes 1/4 to 1 1/2 in., inclusive, and with dimensions conforming with the requirements of the latest issue of ANSI or ASME B18.2.2 or B18.6.3, as applicable. This standard does not include limits for surface discontinuities. Where usage requires such control, limits may be specified separately. For sizes 1/4 through 1 in., this may be done by the statement: Surface discontinuities shall not exceed the limits specified in SAE J122.

Mechanical and Material Requirements for Steel Nuts

SAE J2486-1999 紧固件的张力表明垫圈拧紧方法

This SAE Recommended Practice covers installation and inspection methods for fasteners which are tensioned using Tension Indicating Washers (TIWs) as a means to ensure that adequate tension is developed in mechanically fastened joints. Figure 1 depicts a typical TIW, and Figure 2 depicts a fastener assembly with a TIW before and after tensioning. This document describes practices for the use of TIWs which are typically produced for use with SAE J429 Grade 5 and Grade 8 fasteners or their metric counterparts, although the same principals hold true for bolted joints using other fasteners. Users are advised to contact a manufacturer for advice on use of these products before using them with special fasteners or applications. This document defines and illustrates preferred installation and inspection methodologies. The contents of this document are presented as accurately as possible; however, responsibility for its application lies with the user.

Tension Indicating Washer Tightening Method for Fasteners

SAE J1701-1999 英制系列紧固件加捻张力紧固

This SAE Information Report is provided as a advisory guide. Individual appalication discretion is recommended. The content has been presented as accurately as possible, but responsibility for its application lies with the user. The document covers the variables in the torque-tension relationship: friction, materials, temperature, humidity, fastener and mating part finishes, surfaces, and the kind of wrenching employed. Also described in this document is the torque management required to achieve correct fastener joint tightening. The thread fit of fasteners must be in accordance with Class 2A for external and 2B for internal inch threads.
