5、s has been split into two documents with J2295 covering inch dimensioned fasteners and this standard, J2295M, covering metric dimensioned fasteners. An optional J2295 prefix has been added to the Part Identifying Numbers (PINs) in order to more clearly identify this standard as the source of the PIN

6、. This revision adds Copper Allot 260, Nickel Alloys 625 and 686 and titanium alloy 32 (UNS R55111) for the ASTM F 467and F 468 fasteners while making titanium alloy 19 inactive for new design. For inspection of small lots, the references specifying lot size have been changed. The reference specific

7、ations for dry film lubricants and for electroplating have changed. Hot-dipped and mechanically deposited zinc coatings have been deleted and Zinc/Aluminum) coatings have been added. Guidance has been added to the Note Section regarding the availability and interchangeability of several copper alloy

8、s. Additional configurations of slotted and jam nuts have been added. A note on galling is added to provide guidance when selecting aluminum, titanium, nickel alloys and austenitic stainless steel fasteners. Stainless steel alloys have been updated to agree with those listed in referenced product st

9、andards. The tables identifying material suffixes for the part identification numbers have been made user friendly by: a. Identifying the applicable ASME dimensional standard in the table b. Providing strength information to help the designer select an appropriate fastener. (Strength values are for

10、info only and do not supersede requirements of the referenced product standard). c. Identifying the coatings recommended for each fastener 1. SCOPE This SAE Part Standard covers selected metric screws, hex bolts, and nuts manufactured in accordance with American Society for Testing and Materials (AS

11、TM) 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

12、defined in this document. 1.1 Purpose The purpose of this document is to assist the designer and other personnel by providing requirements and part identifying numbers for the most commonly used fasteners for ship systems and equipment. A part or identification number (PIN) is normally required for

13、all military applications and provides a useful means of communicating fastener requirements to suppliers and manufacturers in a very succinct manner. SAE J2295M Issued JUN2006 - 2 - 1.2 Fastener Part Numbers This document provides part or identifying numbers that can be used to identify metric sock

14、et head cap screws, hex head cap screws, bolts and hex nuts for the parts covered by this document. The parts covered by this document are manufactured in accordance with fastener standards issued by the SAE and ASTM. The part identification number (PIN) identifies material, material strength, coati

15、ngs and special features, nominal diameter, thread configuration, fastener length, marking requirements, along with the applicable ASTM or SAE fastener specification. 1.3 Relationship of J2295M to ISO Standards There is no equivalent ISO standard. There are ISO standards that cover some similar prod

16、ucts. The ASME dimensional standards referenced are similar to ISO standards and these standards usually contain a comparison to ISO dimensional standards. The metric fastener parts in J2295M are based on ASTM and ASME fastener standards. However, these parts are often not stocked and metric fastene

17、rs available from stock are often to DIN, ISO or other standards. 2.

FASTENER PART OR IDENTIFYING NUMBERS 3.1 SAE Fastener Part Sta

33、ndards 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 AS

34、TM 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, coatin

35、g, and other special features with simple part identifying numbers that can be easily recognized by both manufacturers and users. 3.2 Part or Identifying Numbers (PINs) for Selected Fasteners PINs are provided herein for selected metric bolts, cap screws, and hex nuts for the purpose of common logis

36、tics 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

37、 of fasteners and therefore part numbers to cover similar fasteners in this standard have usually not been developed. SAE J2295M Issued JUN2006 - 5 - 3.2.1 PINs for Screws and Bolts Figure 1 provides part or identifying numbers for hex and socket head screws and bolts in accordance with selected AST

38、M and SAE product standards. Table 1 is a listing of the standards with the selected materials identified for metric screws and bolts.
