ASME B107.4-2005 pdf download.Driving and Spindle Ends for Portable Hand, Impact, Air, and Electric Tools (Percussion Tools Excluded).
1 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 be- long in this category and may be added by revision or addition through the usual procedure. This Standard includes dimensions and tolerances for both driving and driven elements where such coordi- nation is important and not established by reference to the pertinent American National Standards. All dimen- sions are in inches and millimeters. 1 2 DEFINITIONS percussion tools: hammers, chisels, scalers, tampers, clay diggers, and rock drills. Percussion tools are excluded from this Standard. rounding values: when the next digit beyond the last digit to be retained is (a) less than 5, the last digit to be retained is not changed (b) 5 or more, the last digit to be retained is increased by one. tool: as used in this Standard, a portable device for per- forming a mechanical operation with power from com- pressed air or electricity and hand operated. 3 NORMATIVE REFERENCES The following is a list of publications referenced in this Standard.

EXAMPLE: (38.214) 5 GAGE USE AND DESIGN The illustrations shown herein are descriptive, not re- strictive, and not intended to preclude the manufacturer of products or gages which are otherwise in accordance with this Standard. Manufacturers may use gages with tighter dimen- sions or tolerances than shown herein to ensure prod- uct acceptance. Tolerances on gage dimensions within the Standard represent new manufactured or purchased gage sizes. The extreme size for all limit (GO and NO GO) gages shall not exceed the extreme limits of products specified within the Standard. All variations (manufacturing tol- erance, calibration error, wear allowance, etc.) in the gages, whatever their cause or purpose, shall bring these gages within the extreme limits of this gage size speci- fied within this Standard. Thus, a gage that represents a minimum limit may be larger, but never smaller, than the minimum specified for the product standard; like- wise, the gage that represents a maximum limit may be smaller, but never larger, than the maximum size spec- ified for the product standard.
