SAE J2295M:2019 pdf free.Fasteners – Part Standard – Cap Screws, Hex Bolts, and Hex Nuts (Metric)
This SAE part standard is for fasteners manufactured to ASTM and SAE fastener standards in accordance with the requirements defined herein. ASTM has issued many fastener standards but generally has not established part or identifying numbers for fasteners to these standards. When using the ASTM or SAE standards, it is necessary to identify the applicable dimensional configuration, coating requirements, and supplemental quality assurance requirements. This SAE part standard provides for the identification of many frequently used fasteners by identifying the applicable dimensional, coating, and other special features with simple part identifying numbers that can be easily recognized by both manufacturers and users.
PINs are provided herein for selected metric bolts, cap screws, and hex nuts for the purpose of common logistics parts identification between designers, builders, repair activities, and equipment operators. Part numbers are provided for only those fastener configurations and materials most likely to be needed. Industry or military specifications and standards with part numbers already exist for many types of fasteners and therefore part numbers to cover similar fasteners in this standard have usually not been developed.
The dimensional requirements for a particular fastener are based on the applicable ASME configuration as identified in the particular fastener standard. Tables 1 and 2 identify the recommended configuration and the applicable ASME dimensional standard. However, if the dimensional standard contains other configurations not specifically recommended herein, the part identification numbering system may allow identification and ordering of these parts. The reasons for the recommended configurations are:
a. When both hex head cap screws and hex head bolts can be procured to the an applicable material standard, the hex head cap screws are preferred since they are suitable for use as both bolts and screws and are often more readily available.
b. Heavy hex configurations have been chosen for the higher strength fasteners and in most cases this is in accordance with the recommendations of the product standards.SAE J2295M pdf free download.
