Product Details

Coupling Nut is used to join compatible threaded rods or studs, with thread engagement and nut grade confirmed for the connection. The current supply reference is DIN 6334 / GB / ANSI / Customized, with Carbon Steel / Alloy Steel / Stainless Steel, Zinc Plated / HDG / Black / Plain, and M6-M36 1/4"-1".

Final dimensions, tolerances, grade or class, coating system, matched components, inspection documents and packing must be confirmed against the purchase order, approved drawing or project specification before production.

Selection & Use Steps

Confirm rod or stud thread diameter, pitch and handedness.
Specify nut length, material or grade, finish and thread engagement at each end.
Confirm whether continuous through-thread travel is required.
Check both rod ends against the approved connection drawing before assembly.

Technical Drawing

Confirm internal thread diameter, pitch, handedness, overall length, width across flats and required engagement at both ends. Specify any through-thread or inspection-hole requirement on the approved drawing.

Application Environment

Match the nut material, grade and finish to the rods and service environment. Connection capacity requires engineering review of the complete assembly.

Installation & Handling Precautions

Do not force mismatched or damaged threads.
Verify engagement at both ends; do not assume a rod can travel through the full nut length.
Use the tightening and inspection procedure specified for the connection.
