ACME tap manufacturer · Ludhiana, India
29-degree ACME threading for suitable motion and drive components.
SWAGIN HSS ACME thread taps are listed for suitable internal ACME threading where profile, pitch, diameter, material, machine and component function are reviewed together. Share the exact drawing for a standard, bulk, export or custom enquiry.
Product overview
ACME thread tap selection is drawing-led. Confirm the 29-degree profile, pitch, diameter, tolerance, thread depth, machine setup, material and the function of the threaded assembly.
ACME selection is not based on size alone. Confirm the exact profile, dimensions, lead, coating and process conditions in the quotation.
Application-led review
Review the tool against the actual component, machine and material. No universal tool-life, load, accuracy or cost-saving result is guaranteed.
Designed for suitable ACME internal-thread requirements in motion, drive and load-bearing components.
Discuss M2, M35 or M42 according to the workpiece material, machine and production requirement.
Supports controlled thread formation and dimensional review for the selected configuration.
Confirm pitch, diameter, tolerance, depth, lead, machine and component function against the drawing.
Review 3-, 4-, 5- or 6-flute configurations and 2-, 4- or 6-thread lead options.
Share size-wise quantities, coating, inspection and repeat-production requirements for quotation.
