Please contact us if you need to verify the threaded section.
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. (Generally applicable 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 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 an M10×250 partial thread bolt, since L (length) is 220 or more, the threaded portion is 10×2+25 = 45mm.Thread Pitch & Hex Width Across Flats Reference List　Hex Bolt Encyclopedia

Hot-dip galvanized coating has a large film thickness, and therefore may not be compatible with other surface treatments. Additionally, even among hot-dip galvanized products, compatibility issues may arise when purchased from different suppliers. In such cases, we may not be able to accept returns, so please be aware of this before proceeding with your purchase.
