6. (Now withdrawn) Nuts with specified proof load values – Fine pitch thread [7] 7. Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm [8] With exception to part 7, which defines test standards, the parts of this standard define properties for fasteners made of carbon steel and alloy steel.
Example (inch fine): For 7 ⁄ 16-20, 1 in ÷ 20 = 0.050 in; 0.437 in − 0.050 in = 0.387 in; The drill sizes that are near this are letter W (0.386 in) and 25 ⁄ 64 in (0.391 in). In addition, 10 mm (0.393 in), and letter X (0.397 in) will work well, although major minus pitch by itself does not tell you this; but the 90% ± 2 pp guideline ...
An M4 nut threaded onto an Allen key socket head screw. A nut is a type of fastener with a threaded hole. ... 7 ⁄ 8: 7 ⁄ 8: 1 + 5 ...
The actual thread heights on both the internal (nut) and external (bolt) threads differ from P / 2 by allowances (or clearances): A minimum root-crest clearance of 0.01 in (0.25 mm) (diametral) between opposing threads with 10 tpi (threads-per-inch) or fewer, and 0.005 in (0.13 mm) for finer pitches.
This standard defines property classes, the metric equivalent of a screw grade, that are almost identical to those defined by ISO 898-1, [2] except for the addition of the 8.8.3 and 10.9.3 classes. These two additional standards are fasteners that have the same mechanical properties as their base property class (i.e. 8.8 and 10.9), but are made ...

Coin dealers will normally grade these coins at or below the ones shown for that respective type, the grades here depend on how bad the issue or issues are. [27] Grading services typically label these coins as "authentic" with x grade "details" (ex: "EF details"). Coins that are uncirculated as mentioned above can not go below an MS-60 grade.
The species was described by Louis Michel François Doyère in 1840; he placed it in the genus Emydium. [1]G. Ramazzotti and W. Maucci classified E. filamentos mongoliensis Iharos, 1973 [4] as a synonym of E. testudo in 1983; this was followed by other tardigradologists. [5]
