Collection: Threading

Thread quality determines assembly performance, and Tool Supply Guy stocks a deep threading catalog for manual and CNC production applications. Our threading range covers hand taps, machine taps, spiral-point taps, spiral-flute taps, form taps, and combination drill-and-tap tools in inch, metric, and specialty thread forms including ACME, NPT, BSPP, BSPT, British Whitworth, and fine-thread series. Thread mills — single-profile, full-profile, and combination drill-thread mills — offer full-profile thread generation in a single CNC pass. Threading inserts for indexable threading holders cover external and internal threading in standard and specialty pitches. Dies, die stocks, and rethreading files cover repair and manual threading needs. Boring bars adapted for threading operations are also available. Taps are stocked in HSS, powdered metal, cobalt, and carbide with and without coating for steel, stainless, aluminum, and heat-resistant alloy applications. Pitch, hand, chamfer style, and material recommendations are specified clearly to avoid ordering errors.
