10.9 Hex bolt(Coarse Steel Unplated 30X180X72 Pitch 3.5
Please contact us if you need to verify the threaded portion.
Depending on the diameter size, lengths equal to or greater than the following will be partial thread.
5 X 25 and above / 6 X 30 and above / 8 X 30 and above / 10 X 35 and above / 12 X 40 and above / 14 X 45 and above / 16 X 45 and above / 18 X 55 and above / 20 X 55 and above / 22 X 60 and above / 24 X 65 and above / 27 X 70 and above / 30 X 75 and above / 33 X 75 and above / 36 X 90 and above / 39 X 95 and above / 42 X 95 and above
Diameters 45 and 48 are essentially partial thread as standard.
Generally, a bolt refers to a screw used together with a nut. Among these, the representative hex bolt has a regular hexagonal head and is tightened using a wrench or spanner. It can be tightened more firmly than slotted or cross recessed screws.
●Full thread = A bolt where the entire length below the head is threaded. (Lengths of 30mm or less are a general guideline.)
●Partial thread (intermediate bolt) = A bolt that is threaded only from the tip partway up the shank.
Partial thread length 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 M10×250 partial thread, since L (length) is 220 or greater, the thread length = 10×2+25 = 45mm.
