Threading
threading creates thread on your product, enabling secure screw or bolt fastening for precise mechanical assemblies.

Threading on CNC work is the external or internal thread cut or rolled on the turned or milled blank. It takes the screw or nut the assembly needs. Spec the standard (metric, UNC) with the machine quote.
Threading is a CNC finishing step on AIHFABS. It runs after milling or turning so the blank leaves closer to a usable part — not only a machine finish. Use this page to decide whether Threading matches color, wear, or assembly needs before you upload a file.

Finishing is quoted with the machine work. Select Threading in checkout, review price and lead time, and keep machining plus post-processing on one order instead of sending a raw blank to a second shop.
Threading can hide cutter marks, even out color, or leave a uniform skin on housings, brackets, and review samples.
Depending on the process, Threading may improve wear, corrosion resistance, or grip so the machined part survives handling and end use.
When Threading sits on the same traveler as milling or turning, the part arrives closer to install-ready — color, coat, or threads already on it.
Ordering Threading uses the same upload as a standard CNC quote. You do not need a separate finishing RFQ for catalog options.
Use STEP, STP, or another supported format. The quoter reads the stock so finishing can be priced against the actual blank.
Pick milling, turning, or another CNC route, then add Threading and any other finishing the part needs.
Review options, confirm quantity, and place the order. Machining and finishing stay on one timeline and one invoice.
Threading is typically applied to metals — and some plastics — after CNC machining. Compatibility depends on alloy, wall thickness, and whether the surface can be reached by bath, media, or a tap. Deep pockets, thin walls, and datum faces may need a review. If the automatic quote cannot apply Threading, request a manual quotation.
Need Threading on a batch, a mixed set, or a part that also needs tapping or paint? Keep those options in the same quote so lead time includes the full stack.

Threading cuts or forms threads in printed plastic or metal. Wall thickness around the hole must hold the tap or thread. Heat-set inserts are an option when the printed material is too soft for a cut thread.
Tapping and threading remove material inside the hole and can raise a slight burr at the entry. Keep the thread length and major diameter in the CAD or the quote notes. Nearby thin walls may need a boss.
Printed threads are coarse. Threading cuts a cleaner internal or external thread for machine screws. Call out the thread spec (for example M3×0.5) and whether you need a heat-set insert instead.
Upload the CAD file, choose a print process and material, then turn on Threading. Price and lead time update on the same order. If the automatic quote cannot apply it, request a manual quotation and note fits or color codes.
