本SAE推荐规程提供了一个统一的程序和性能要求，用于评估售后市场乘用车和轻型卡车（SAE J1965涵盖的双轮除外）和多用途乘用车上正常公路使用的紧固系统。紧固系统包括车轮、车轮螺栓和车轮螺母，以及车辆配合面。钢和铝配合面的摩擦系数基于可用信息提供。在设计和验证每辆特定车辆的车轮附件时，必须考虑许多因素。如果该程序用于原始设备应用，则车辆制造商的规范将取代上述规范。

This SAE Recommended Practice provides a uniform procedure and performance requirements for evaluating fastening systems for normal highway use on aftermarket passenger cars and light trucks (except dual wheels, which are covered by SAE J1965) and multipurpose passenger vehicles. The fastening system includes the wheel, wheel bolts, and wheel nuts, as well as vehicle mating surface. The coefficients of friction for steel and aluminum mating surfaces are provided based on information available. Many factors must be considered in design and validation of wheel attachments for each specific vehicle. Where the procedure is used for original equipment applications the vehicle manufacturers specifications supersede those noted.
