Bolt and Capscrew Sizes for Use in Construction and Industrial Machinery
- Ground Vehicle Standard
- J370_200604
- Cancelled
Scope
This SAE Recommended Practice covers the use of preferred bolt and capscrew sizes, wherever applicable, on construction and industrial machinery to ease serviceability.
Designers, in their efforts to determine the proper fastener for heavy equipment, sometimes overlook the practical aspects of serviceability. When a particular component requires frequent service, it is much faster and easier for the serviceman to work with common size, easily distinguished bolts and capscrews which require a minimum of tools.
Section 4 lists eight diameters of recommended bolts and capscrews, some of which can be found in any hardware store, require only standard tools, are easy to distinguish, and at the same time cover proof loads from 1043 kg (2300 lb) on up at convenient intervals.
While some applications may require other sizes and/or fine threaded fasteners for greater camping forces and/or area restrictions, the convenience of UNC threads in the sizes indicated is preferred wherever possible.

Issuing Committee
The Fasteners Committee is dedicated to serving the users of fasteners by identifying the need for and developing and maintaining Standards, Recommended Practices and Information Reports in the area of fasteners (including nuts, bolts, washers, screws, pins, rivets and other fasteners) for use with various Land-Sea vehicular applications. Areas addressed include coding, identification, dimensional, performance and procurement requirements as well as quality, shipping, storage, testing methods, application and installation guidelines. The SAE Fastener Committee interacts with other SAE committees and other technical societies, international standards organizations and government agencies to provide global standardization and avoid duplication of effort.
