WORKING OUT A TAPER

3/8”

5-3/4”

Bolt hole diameters are as follows: For 1/2” and 5/8” bolts, the bolt hole shall be 1/16” larger than the bolt diameter. For 3/4” bolts and larger, the bolt hole shall be no more than 1/8” larger than the bolt diameter.

1. Subtract dia (a) from dia (b) 2. Divide dim (c) by answer to 1 3. Taper is therefore answer to (2):1 E.g. (a) = 0.75” (b) = 1” (c) = 2/5”

Example (b) 1” - (a) 3/4” = 0.25 (c) = 2.5 divided by 0.25 = 10 1 in 10 is standard Metric taper 1 in 12 is standard Imperial taper
