Generally, a bolt refers to a screw used together with a nut. Among these, the representative hex bolt features 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 for lengths of 30mm or less)
●Partial thread (standard bolt) = A bolt that is only threaded from the tip partway up the shank.
Partial thread length calculation method (approximate guide)
L = up to 129　　　Nominal thread diameter × 2 + 6
L = 130–219　　　 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 greater, the thread length is 10×2+25 = 45mm.
