SAE International has just released a new 2012 Edition for J995, “Mechanical and Material Requirements for Steel Nuts,” and it’s available now from Document Center Inc. The new 9-page revision covers the mechanical and material requirements for three grades of steel nuts used in automotive and related engineering applications.
Nuts are covered in sizes 1/4 to 1-1/2 inch, inclusive, and with dimensions conforming with the requirements of the latest issue of SAE J482 or ASME B18.2.2. However, machine screw nuts are not covered in this standard.
SAE J995 does not include limits for surface discontinuities. Where usage requires such control, limits may be specified separately. For sizes 1/4 through 1 inch, this may be done by the statement: “Surface discontinuities shall not exceed the limits specified in ASTM F812/F812M.”
Changes in this edition include the following:
Grade 2 has been added to all nut types. And nut types that are in use but not previously covered have also been added.
Appendix Tables A2 and A3 are provided for easier use when determining specific proof load values.
Modifications to the quality requirements bring them into line with those of ASTM to simplify the evaluation of product in testing laboratories.
And there is a new illustration to better explain the grade markings for the various SAE nuts (no disrespect intended)…
