BLT642H Ceramic Body, Locking Ring and Nozzle Guide
Partager
For a confirmed BLT642H cutting head, identify the ceramic body, locking ring, or nozzle before selecting a consumable. This is an identification and purchasing reference, not an offer for a complete cutting head, a complete bill of materials, or a general assembly instruction.
Short answer
The BLT642H manual treats the ceramic body, locking ring, and nozzle as separate parts. Section 3.2.5 gives their order: ceramic body, locking ring, then nozzle. That relationship helps identify the role of a removed item; it does not prove that parts with a similar thread, shape, or colour are interchangeable.
The store’s source-backed ceramic-body mapping lists Y.Z.C0034 with M11×0.75 for BLT642H. Use the exact ceramic-body Variant only when the complete record matches. A locking-ring identity needs its own confirmation; this guide does not treat a locking ring as the ceramic body or the nozzle.

Three separate roles
The BLT642H product view identifies the ceramic body lock ring and ceramic body. Section 3.2.5 identifies the nozzle and states the ceramic body → locking ring → nozzle order. Appendix A provides the related structure labels, including D41mm, M11 for the ceramic part and M11, H15 for the nozzle.
| Manual component | Customer-facing role | Do not replace it with |
|---|---|---|
| Ceramic body | The ceramic component in the nozzle-end assembly | A locking ring or nozzle merely because it fits nearby |
| Locking ring | The separate part that secures the ceramic body in the stated sequence | The ceramic body itself |
| Nozzle | The separately named nozzle installed after the ceramic body is secured | A ceramic body or locking ring |
The illustrated M11 references are structural labels for BLT642H. They do not turn a shared thread reference into interchangeability or a complete shopping list.
Identify the component before selecting a route
- Confirm the installed model is BLT642H.
- Decide which role the removed part has: ceramic body, locking ring, or nozzle.
- Record the complete Part Number and any thread or structure marking from the component or its package.
- Match that record to one source-backed product entry; do not use the manual’s role diagram to infer an unprinted ordering code.
- Treat a matching thread as a cross-check only. It is not evidence that a locking ring, ceramic body, and nozzle are substitutes.
The conditional ceramic-body route
The current store mapping lists the following ceramic-body selection record for BLT642H:
| Complete record | Exact route | Boundary |
|---|---|---|
Y.Z.C0034 / M11×0.75 / ceramic body / listed BLT642H |
Open the exact Variant | Use only after the complete Part Number, component role, and BLT642H model match |
This route does not identify an unmarked locking ring or say that the ceramic body is bundled with a locking ring or nozzle. If the part in hand is a ring rather than the ceramic body, confirm its complete identifier separately before selecting any product.
Use the sequence as a role check
Section 3.2.5 uses the ceramic body → locking ring → nozzle order to distinguish three component roles. It does not supply a generic torque, maintenance interval, process setting, or safe procedure for other models. Follow the official BLT642H Product Manual (V1.1, 2022-08-19), its safety notices, and qualified-service requirements.
When to request confirmation
Request confirmation if the model is not BLT642H, the part is unmarked, the item appears to be a locking ring rather than the ceramic body, or the only apparent match is an M11 thread. A product image, thread, or adjacent assembly position cannot establish a complete purchase record.
Use the replacement-part confirmation guide to collect the model, component role, full code, and a clear label photo. The guide is an identity-preparation path, not an automatic compatibility finder.
