Scope
Content
This SAE Standard covers the mechanical and material requirements for inch-series steel bolts, screws, studs, screws for sems1, and U-bolts2 in sizes to 1-1/2 in. inclusive.
The term “stud” as referred to herein applies to a cylindrical rod of moderate length threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared, or similar products which are more closely characterized by requirements shown herein for bolts.
The mechanical properties included in Table 1 were compiled at an ambient temperature of approximately 20 °C (68 °F). These properties are valid within a temperature range which depends upon the material grade used and thermal and mechanical processing. Other properties such as fatigue behavior, corrosion resistance, impact properties, etc., are beyond the scope of this document and responsibility for ensuring the acceptability of the product for applications where conditions warrant consideration of these other properties shall be borne by the end user.
Rationale
Content
Several ISO 898-1 material classes are comparable to SAE J429 material grades. Chemical revisions were made in Table 2 to bring this standard further in alignment with ISO 898-1 such as allowing non-alloy steels for Grade 8 products. One notable difference between ISO 898-1 (2009) and SAE J429 (2012) is that the minimum carbon level is higher for Grade 8 than for Class 10.9 products made from alloy steels and from carbon steel with additives. In addition this revision corrects a few errors and inconsistencies discovered since the publication of the 2011 revision.
