Detailed Information

1 SCOPE
This Standard describes a gage and procedure for checking bolt or screw straightness at maximum material condition (MMC) and provides default limits when not stated in the applicable product standard.

2 COMPARISON WITH ISO 4759-1:2000
This Standard uses an adjustable gage, instead of plain sleeve gages like the example shown in ISO 4759-1 Annex C, Figure C.24. The adjustable gage avoids the necessity of a different gage for each diameter-length combination, and for each difference in the specified tolerances on diameter, or straightness, or both, of the fastener.
