Description

Do you need a partially threaded machine screw that works reliably even in damp, salty, or chemically demanding environments? Hexagon bolt in Duplex 1.4462 stainless steel according to DIN 931 is built to withstand heavy corrosion and maintain strength over a long period. It combines high tensile strength with reliable durability and is optimized to withstand heavy mechanical stress and frequent use.

FIELD OF APPLICATION

Perfect for fastening in marine environments, coastal construction, piers, boats, the food industry, and chemical plants where high corrosion resistance is a requirement. The partially threaded design provides a stable and vibration-resistant connection. Easy to install with a socket wrench or spanner and requires minimal maintenance even during continuous operation.

FREQUENTLY ASKED QUESTIONS (FAQ)

What is the difference between DIN 931 and ISO 4014?

DIN 931 is the traditional German standard for partially threaded hexagon bolts and is now equivalent to the international standard ISO 4014. The dimensions and function are essentially the same, and the products are interchangeable in most bolted joints. However, the wrench size differs for the dimensions M10, M12, M14, and M22.

Why choose a partially threaded hexagon bolt in Duplex 1.4462?

Duplex 1.4462 combines very high mechanical strength with better resistance to pitting and crevice corrosion than conventional acid-proof A4 steel. The unthreaded part of the shank provides a good fit in the joint and can withstand shear loads.

In what environments is DIN 931 in Duplex 1.4462 suitable?

The bolt is recommended for demanding environments such as offshore, marine installations, chemical processing plants, and the pulp and paper industry. It is particularly suitable in environments with high levels of chlorides or salt water where the risk of pitting, crevice, and stress corrosion is otherwise high.
