Square keys are used for smaller shafts and rectangular faced keys are used for shaft diameters over 6.5 in (170 mm) or when the wall thickness of the mating hub is an issue. Set screws often accompany parallel keys to lock the mating parts into place. [3] The keyway is a longitudinal slot in both the shaft and mating part.
The length L of the split pin is defined as the distance from the end of the shortest tine to the point of the eyelet that contacts the hole. The most common type of split pin is the extended prong with a square cut, but extended prongs are available with all of the other types of ends.
When converting between module and DP there is an inverse relationship and normally a conversion between the two units of measure (inches and millimeter). Taking both of these into consideration the formulae for conversion are: MM = 25.4 / DP and DP = 25.4 / MM [3]

Also, there are limits on the size of internal cuts. Common internal holes can range from 0.125 to 6 in (3.2 to 152.4 mm) in diameter but it is possible to achieve a range of 0.05 to 13 in (1.3 to 330.2 mm). Surface broaches' range is usually 0.075 to 10 in (1.9 to 254.0 mm), although the feasible range is 0.02 to 20 in (0.51 to 508.00 mm).

The tolerance of the part that this gauge checks is 0.30 mm, where the lower size of the hole is 12.60 mm and the upper size is 12.90 mm, every size outside this range is out of tolerance. This may be initially expressed on the parts drawing in a number of styles; three possibilities may be 12.75 ± 0.15 mm; 12.60 +0.30 −0.00 mm; 12.90 +0.00
