Short Description:

DIN 6334 Hex Coupling Nuts

In installations where threaded rods must be extended, fixtures secured, and support structures aligned, DIN 6334 hex coupling nuts have become the preferred connector for joining two same-spec rods end to end. Handan Haosheng Fastener Co., Ltd., a leading manufacturer based in Handan, China, specializes in producing high-quality DIN 6334 hex coupling nuts, offering an elongated hexagonal body with a long internal thread and wrench-friendly hex exterior for reliable, adjustable connections.

At Handan Haosheng Fastener Co., Ltd., our DIN 6334 coupling nuts are engineered to match each assembly with the right length, material, and thread structure, helping equipment builders extend rods and stabilize fixtures without custom housings.

Why Choose Haosheng DIN 6334 Coupling Nuts?

Our coupling nuts deliver several key advantages:

• ✔ Extended 3d thread body – the elongated hex body gives long thread engagement, joining two rods end to end for extensions, fixtures, and supports.
• ✔ Metric sizes M6-M36 – common products follow a 3d length, so M12 is 36 mm and M16 is 48 mm per specification.
• ✔ Three material families – carbon (20/35/45), alloy (40Cr/35CrMo), and stainless 304/316, matched to strength and corrosion needs.
• ✔ Five finish options – plain, blue zinc, yellow zinc, zinc-nickel, and zinc-flake, selected with thread fit and environment in mind.
