Page 52 - The permissible variation in weight is 5 per cent above and 5 per cent below. Furnished with threads and couplings and in random lengths unless otherwise ordered. Taper of threads is \" diameter per foot length for all sizes.
Page 75 - Meter — the unit of length. From this the units of capacity (Liter) and of weight (Gram) were derived. All other units are the decimal subdivisions or multiples of these. These three units are simply related, eg, for all practical purposes one Cubic Decimeter equals one Liter and one Liter of water weighs one Kilogram. The metric tables are formed by combining the words "Meter...

Page 93 - US STANDARD THREADS, BOLTS AND NUTS The tap drill diameters in the table provide for a slight clearance at the root of the thread, in order to facilitate tapping and reduce tap breakages. If full threads are required, use the diameters at the root of the threads for the tap drill diameters Machinery's Handbook Diameter No.
Page 72 - LOUIS A. FISCHER In the United States the measures of weight and length commonly employed are identical with the corresponding English units, but the capacity measures differ from those now in use in the British Empire, the US gallon being defined as 231 cu. in. and the bushel as 2150.42 cu. in., whereas the corresponding British imperial units are, respectively, 277.418 cu. in., and 2219.344 ou.
Page 89 - Fit (Class 1). Recommended as a commercial standard for tapped holes in the numbered sizes only. May be used with screws of other classes to obtain quality of fit desired.
Page 89 - Close Fit (Class 4). — Includes screw-thread work requiring a fine snug fit, somewhat closer than the medium fit, such as highgrade aircraft parts, etc. In this class of fit selective assembly of parts may be required. It is not considered practicable as a commercial standard for tapped holes of the numbered sizes.
Page 57 - Pipe — Black and Galvanized All weights and dimensions are nominal The permissible variation in weight is 5 per cent above and 5 per cent below.
