description

This M12×30 hexagon head bolt is made of high-strength alloy steel and heat-treated for improved mechanical performance. Its precisely rolled threads feature regular tooth profile and smooth engagement with nuts. The surface adopts Dacromet coating. Unlike ordinary paint or galvanizing, the thin and compact coating offers excellent salt spray and moisture resistance together with good self-lubrication. It avoids thread jamming during assembly and hydrogen embrittlement risk, ideal for harsh outdoor working conditions of construction machinery. Widely used on frequently vibrating parts such as paver feeding mechanisms, guard plates and supports, this original replacement fastener greatly extends service life during maintenance and machine assembly.

- Original standard dimension for direct replacement, perfectly matched for RP705 and easy stocking

FAQ

Q: How to choose between Dacromet bolts and ordinary galvanized bolts?
A: This Dacromet bolt is preferred for humid, waterside, coastal or long-term outdoor working conditions. Ordinary galvanized bolts are acceptable for dry locations.

Q: Does the bolt remain rust-proof after the Dacromet coating is worn?
A: If large areas of coating are scratched and the base metal is exposed, corrosion protection drops sharply. Direct replacement is recommended instead of long-term reuse.

Q: Do we need to adjust the tightening torque for this bolt?
A: Follow the torque specified in the official maintenance manual. Dacromet offers lubrication and brings slightly higher preload under the same torque. Do not over-tighten to avoid thread damage.

Q: Can it be assembled with ordinary galvanized nuts?
A: Assembly is possible, yet galvanic corrosion may occur between dissimilar coatings. Matching Dacromet fasteners are recommended for long-term service.
