Threaded Rod

A threaded rod is a long bar with threads along its length. It is used to join parts, hang items, or provide adjustment.

A threaded rod joins or clamps parts along its length and can be cut to the length a job needs. It takes a nut and often a washer of the same thread and class.

Zinc plating gives a bright finish and mild corrosion resistance. Hot dip galvanising gives a thicker coating for outdoor use. Black oxide gives a dark finish with light oil protection.

This kind of rod is often made in steel, alloy steel, stainless steel, or brass. Steel grades are common for general use. Alloy steel grades are used for high strength.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a mill test certificate or certificate of conformance if you need traceability. Check the thread, length, and straightness against your requirement. Inspect for thread damage or coating defects on receipt.
