Hex bolt(Partial thread(Coarse Steel Unplated 12X120 Pitch 1.75

Generally, a bolt refers to a screw used together with a nut. The most representative type is the hex bolt, which has a regular hexagonal head and is tightened using a wrench or spanner.
It can be tightened more securely than slotted or cross recessed screws.
●Full Thread = A bolt in which the entire length below the head is threaded. (Generally used as a guideline for lengths of 30mm or less.)
●Partial Thread (medium bolt) = A bolt that is only threaded from the tip partway up the shank.
Partial Thread Calculation Method (approximate guideline)
L = up to 129　　　Nominal thread diameter × 2 + 6
L = 130 to 219　　 Nominal thread diameter × 2 + 12
L = 220 and above　　　　 Nominal thread diameter × 2 + 25
Example: For an M10×250 partial thread bolt, since L (length) is 220 or more, the threaded portion is 10×2+25 = 45mm.
