This SAE Part Standard covers selected metric screws, hex bolts, and nuts manufactured in accordance with American Society for Testing and Materials (ASTM) and SAE fastener standards. This document covers fastener materials often used in ship systems and equipment but its use may be applied wherever fasteners of the covered materials are used. This document permits the fasteners to be identified and ordered by a part or identifying number (PIN) as defined in this document.
The use of SAE J2295M has been limited due to the fact that most of the metric nuts and bolts available in the United States have not been made to the ASME dimensional standards referenced in SAE J2295. Rather, most of the available metric products available have been manufactured to DIN and ISO standards. ASME has recently been withdrawing their metric dimensional standards in favor of the ISO standards. Other references in SAE J2295 may also have been withdrawn or superseded.
Generally, the fasteners to ISO and other National metric fasteners available on the market are interchangeable with those covered by SAE J2295M. It is recommended that ISO metric fasteners be used for new design. For support of current designs, SAE J2295M requirements can be compared to fasteners manufactured to ISO and other National Metric Standards to determine the suitability of these more readily available fasteners.
However, it is considered important that SAE J2295M standard be available for reference to support those applications where it has been used. The Part Identification Numbers (PINs) in SAE J2295M may have been used on drawings and users may need to refer to this part standard to identify the characteristics of these fasteners.

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
