Threaded Rods & Studs — Cut to Length, Any Thread

What this part is and where it is used

A threaded rod and a stud are both straight, headless lengths of bar with an external thread — the difference is where the thread sits. A fully threaded rod is threaded end to end and is usually cut to length, while a stud carries threads on both ends (double-end) or one end (tap-end) with a plain shank between. Threaded rods and studs are machined to your drawing, which defines the diameter, thread, overall length and material.

Buyers order these when a headed bolt does not suit: a stud that stays in place while a nut runs onto the exposed end, a rod that passes through a clamp or flange, or a length no catalog covers. A stud and nuts form the joint — the stud holds position and the nut applies the clamp — and we can supply matched custom nuts and custom washers.

Types of threaded rods and studs we manufacture

We cut the common forms to print:

• Fully threaded rods — threaded end to end and cut to your length.
• Double-end studs — thread on both ends with a plain shank between.
• Tap-end studs — thread on one end to seat in a tapped hole, the other end takes a nut.
• Stud bolts and specialty lengths with custom thread runs and shoulders.

A stainless stud bolt, a bolt and stud set, or a rod with a left-hand thread on one end is one drawing away. We machine each to the exact length and thread run your print calls for, rather than trimming a stock bar and hoping the thread lands right.

Materials, threads and finishes

Common materials are aluminium (6061, 7075), stainless steel (303, 304, 316L), carbon and alloy steel (1045, 1215, 4140), brass and copper, and titanium. Stainless stud bolts suit corrosion-facing flanges and clamps; see our stainless steel parts, aluminium parts, steel parts, brass and copper parts and titanium parts pages.

Threads are cut to metric or inch references, or to DIN and ANSI/ASTM standards — our thread standards page lists the options. We cut coarse and fine pitches and left-hand threads, and can put a different thread on each end of a stud. Finishing runs through our vetted partner network under one quality process: zinc plating, black oxide and passivation, among others.

Industries and applications

Studs and bolts appear in oil and gas, hydraulic and pneumatic, automotive, marine and agriculture assemblies. Double-end studs and fully threaded rods serve pipe flanges, clamps and structural ties, while tap-end studs suit engine and pump mounting.
