Turned components
Round inserts, bushings and spacers routed by material, tolerance and quantity.
Custom Nuts, Inserts & SpacersProduct reference. Drawing revision, dimensions, material, process, inspection and packing follow the confirmed order.
Internally threaded & turned components
Custom Nuts, Inserts & Spacers
Custom nuts, threaded inserts, bushings and spacers sourced by released drawing, internal and external geometry, thread, knurl or press-fit feature, material, host-part interface, finish, inspection and assembly requirement.
- Released drawing, revision, units, quantity and intended interface
- Internal thread standard, size, pitch, fit and gaging
- External body, flange, knurl, slot, wall and concentricity
- Material, hardness/condition, heat treatment and finish
- Host material/hole or mating part, installation method and inspection
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 drawing and part revision with mating or host-part information where relevant | Confirmed per RFQ |
| Geometry / tolerances | Internal/external diameters, thread, flange, wall, length, knurl, slot, chamfer and tolerances | Confirmed per RFQ |
| Material / condition | Material specification, condition or hardness plus corrosion and host-material compatibility | Confirmed per RFQ |
| Process / finish | Turning, forming, knurling, broaching, heat treatment, coating and installation route as specified | Confirmed per RFQ |
| Inspection / approval | Thread gaging, concentricity/runout, dimensional report, installation sample and documents | Confirmed per RFQ |
| Packing / commercial | Quantity by part number, sample plan, packaging orientation, labels and destination | Confirmed per RFQ |
Drawing-based sourcing
The mating interface is part of the component definition
For custom nuts and inserts, the internal thread is only one controlled feature. External geometry, flange, knurl, press-fit diameter, wall thickness, lead-in, hardness and the mating hole can determine installation behaviour.
For spacers and bushings, bore, outside diameter, length, squareness and concentricity may be more important than appearance. XHT quotes against the released drawing and stated assembly conditions.
What to include in your RFQ
- Released drawing, revision, units, quantity and intended interface
- Internal thread standard, size, pitch, fit and gaging
- External body, flange, knurl, slot, wall and concentricity
- Material, hardness/condition, heat treatment and finish
- Host material/hole or mating part, installation method and inspection
Controlled RFQ fields
Items that define a comparable quotation
Common RFQ fields for custom nuts, inserts, bushings and spacers. The drawing and mating interface control the review.
| Selection | Buyer input | Control |
|---|---|---|
| Thread / bore | Thread system, size, pitch, class/fit, gaging or plain-bore tolerance | Confirmed per RFQ |
| External geometry | Hex/round form, flange, knurl, serration, slot, shoulder and chamfer | Confirmed per RFQ |
| Fit / interface | Host material, receiving-hole limits, press/clearance fit and installation direction | Confirmed per RFQ |
| Material / hardness | Alloy, condition, heat treatment, hardness and galvanic compatibility | Confirmed per RFQ |
| Finish / cleanliness | Coating, passivation, lubricant, residue and masking limits as specified | Confirmed per RFQ |
| Inspection / samples | Thread gages, runout/concentricity, installation sample and records | 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
Confirm both the component and the host interface
A press-fit or knurled insert cannot be reviewed only by its outside diameter. Host material, hole preparation, wall, installation method, retention requirement and acceptance test must be stated by the buyer.
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.
