End-specific threaded components
Custom Studs & Threaded Parts
Custom studs and threaded parts sourced by drawing-controlled thread at each end, plain-body geometry, length datum, runout, material and properties, heat treatment, finish, inspection, marking and packing.
- Released drawing number, revision, units and order quantity
- Thread standard, size, pitch, fit and length for each end
- Overall/body length, diameter, shoulders, reliefs and end details
- Material, property requirement, heat treatment and finish
- Thread gaging, orientation, critical dimensions, documents and packing
A product page is an RFQ starting point, not a blanket capability or compliance claim. Final feasibility, process route, tolerances, testing, lead time and supply scope are stated only in the written quotation.
Quotation control
Information used to review the drawing RFQ
The released file, revision, units, tolerance scheme, material, process, quantity, inspection and destination are aligned before supplier routing.
| Field | Review basis | Order control |
|---|---|---|
| Part / file basis | Released stud or threaded-part drawing with end identification and revision | Confirmed per RFQ |
| Geometry / tolerances | End-specific threads, lengths, fits, runout, body diameter, shoulder, relief, chamfer and datum | Confirmed per RFQ |
| Material / condition | Material specification, grade, heat treatment, hardness or mechanical properties | Confirmed per RFQ |
| Process / finish | Thread rolling or cutting, machining, heat treatment, coating and masking as ordered | Confirmed per RFQ |
| Inspection / approval | Thread gages at each end, length and runout checks, material records and sample approval | Confirmed per RFQ |
| Packing / commercial | Quantity, matched nuts/accessories if included, identification, protective packing and destination | Confirmed per RFQ |
Drawing-based sourcing
Treat each end as a separate controlled interface
Custom studs often have different functions at each end. Diameter, pitch, fit, engagement length, thread length, runout, chamfer, relief and orientation must be recorded separately rather than inferred from a single trade name.
Overall length may use different datums, and coatings can affect fit. XHT coordinates clarification and sourcing only after the buyer-approved drawing and thread definitions are complete.
What to include in your RFQ
- Released drawing number, revision, units and order quantity
- Thread standard, size, pitch, fit and length for each end
- Overall/body length, diameter, shoulders, reliefs and end details
- Material, property requirement, heat treatment and finish
- Thread gaging, orientation, critical dimensions, documents and packing
Controlled RFQ fields
Items that define a comparable quotation
Common RFQ fields for custom studs and threaded parts. The released drawing controls every end-specific requirement.
| Selection | Buyer input | Control |
|---|---|---|
| End A thread | Standard, diameter, pitch/TPI, fit, thread length, runout and end form | Confirmed per RFQ |
| End B thread | Standard, diameter, pitch/TPI, fit, thread length, runout and end form | Confirmed per RFQ |
| Body / length | Overall datum, plain-body diameter, shoulder, relief, orientation and straightness | Confirmed per RFQ |
| Material / properties | Material grade, heat treatment, hardness or mechanical requirement | Confirmed per RFQ |
| Finish / fit | Coating, masking, lubrication and post-finish gaging requirement | Confirmed per RFQ |
| Inspection / packing | End identification, thread gages, dimensional report and protection | Confirmed per RFQ |
Missing information: XHT may raise clarification points or propose a documented alternative for review. No changed material, dimension, tolerance, process or finish becomes the order basis without buyer approval.
Technical & file control
Do not assume both ends share the same thread definition
Different pitch, fit, engagement, coating or orientation may apply at each end. The quotation must preserve the buyer’s end labels and drawing datums so that a visually similar stud is not treated as interchangeable.
Before sharing files: Send only technical files you are authorized to transmit. If an NDA, access restriction or special transfer method is required, agree the route with XHT before uploading the file.
Typical sourcing routes
The route follows geometry, process and quantity
Examples guide the RFQ only. Supplier selection and process feasibility remain subject to the released requirement and written quotation.
02
Tap-end parts
Insertion and nut-side requirements reviewed with the mating assembly.
03
Reduced-body studs
