Name: Buttress Thread Taps
Brand: FuRui Tooling

Product details

Buttress taps address a special internal-thread profile and should be ordered from a clearly defined thread drawing. The catalog identifies this family, but a product name alone does not settle flank geometry, direction or size. Include the mating-part requirements and required inspection details so the actual tool specification can be agreed before production.

Asymmetric profile review

Provide the drawing's flank angles, radii and complete thread designation.

Direction matters

State thread hand and orientation requirements explicitly for the proposed component.

Dedicated inspection inputs

Identify the critical profile and fit checks required for tool acceptance.

Specifications & model range

Source transcription for inquiry only, not a resolved ordering table. The source contains a two-column pitch field whose meaning is not explained and values that conflict with some printed designations; these pitch columns have intentionally been omitted. Repeated designations with different dimensions (rows 13/14 and 2/24) are preserved with row IDs. Every selection requires a confirmed profile drawing, pitch, handedness and tool dimensions before quotation or production.

Drawing confirmation requiredSome source model codes appear more than once with different geometry, and pitch subcolumns are not fully labelled. Do not select solely by the displayed code; confirm the profile, pitch and full dimensioned drawing.

Thread form: Buttress

Application scenarios

Typical selection contexts for this series, not customer project claims. Confirm machine compatibility and cutting conditions for your setup.

Special threaded mechanisms

Producing an internal buttress profile defined by the mechanism drawing.

Axial-load components

Reviewing tooling for parts whose designer specifies a buttress thread.

Legacy tool replacement

Matching a special tap against an existing tool and mating-part documentation.

Compare alternative interfaces and complementary tooling. A related series is not automatically interchangeable.

Product FAQ

Selection questions for Buttress Thread Taps.

Request a quote

Can a buttress tap be chosen from diameter and pitch alone?

Provide the complete profile drawing too, including the specified flank geometry and direction.

Does the tap's profile establish the component's load capacity?

No. The component designer must establish load capacity. This page concerns the tool needed to produce the specified thread.

Can the existing special tap serve as a reference?

Yes, include photographs and measured dimensions, but a mating-part or original tool drawing improves confirmation.

Will a trapezoidal tap produce an equivalent thread?

No. Treat these as distinct profiles and follow the component's exact thread requirement.
