scOPE
This Standard applies to portable power tools for drilling, grinding, polishing,sawing, and driving threaded fasteners,and hand tools for driving threaded fasteners. Other tools not classed as percussion tools belong in this category and maybe added by revision or addition through the usual procedure.
This Standard includes dimensions and tolerances for both driving and driven elements where such coordination isimportant and not established by reference to the pertinent American National Standards. All dimensions are in inchesand millimeters.
2 DEFINITIONS
percussion tools: hammers, chisels,scalers, tampers, clay diggers, and rock drills.Percussion tools are excluded from thisStandard.
rounding: In this Standard, calculated values are rounded off as follows:
(a) if the next digit after the last digit to be retained is less than 5, the last digit to be retained is not changed(b] if the next digit after the last digit to be retained is 5 or greater, the last digit to be retained is increased by onetool: as used in this Standard, a portable device,either hand operated or powered by compressed air or electricity, forperforming a mechanical operation.

5 GAGE USE AND DESIGN
The illustrations shown herein are descriptive, not restrictive, and are not intended to preclude the manufacture ofproducts or gages that are otherwise in accordance with this Standard.
Manufacturers may use gages with tighter dimensions or tolerances than shown herein to ensure product acceptance.Tolerances on gage dimensions within the Standard representnew manufactured or purchasedgage sizes.The extremesize for all limit (G0 and No Go) gages shall not exceed the extreme limits of products specified within the Standard.Allvariations (manufacturing tolerance, calibration error, wear allowance, etc.) in the gages, whatever their cause orpurpose, shall bring these gages within the extreme limits of the gage size specified within this Standard.Thus, agage that represents a minimum limit may be larger, but never smaller, than the minimum specified for theproduct standard; likewise, the gage that represents a maximum limit may be smaller, but never larger, than themaximum size specified for the product standard.
