Stainless Threaded Rod (Studding)

Threaded Rod

Stainless UK produce stainless steel threaded rod. Also referred to as stud, studding, all-thread or threaded bar.

Threaded rod is produced using the thread rolling process. This ensures a smooth form and enhances tensile strength.

Sizes up to M76 double end or fully threaded available.

It is important to clearly specify both the grade of material and strength class when ordering.

For threaded bars, the specification should include the finish on the smooth portion, e.g as rolled, or class of polish.

For single or double-ended threaded bars the specification should include bar length and end thread lengths

Stainless steel metric studding can be supplied with a range of accessories which can be manufactured to meet individual contract requirements.

NUTS AND COUPLERS

Load nuts and couplers have been designed to provide a strength of anchorage equal to the theoretical minimum required by the threaded bar. Lock nuts are for locking purposes only.
