Garage Door Track Bolts: BT-S910 Size Record

Garage Door Track Bolts can become surprisingly difficult to source when one product record contains both metric and inch size notation. In the available catalog, NINGBO BAOTENG TECHNOLOGY CO.,LTD identifies model BT-S910 as a Track Bolt, with the specification M6×16 and the English size 1/4″×5/8″. Those are the complete verified product-level size fields available for this model.

The practical sourcing rule is simple: keep BT-S910, M6×16, and 1/4″×5/8″ together as one catalog record. The two size expressions should not be separated into two assumed products, and they should not be treated as proof of universal interchangeability with other bolts carrying similar dimensions.

NINGBO BAOTENG TECHNOLOGY CO.,LTD is described in the available company information as producing hardware accessories and OEM products for garage doors, industrial doors, commercial doors, and residential doors. Its broader garage door hardware and OEM product context can help buyers understand the catalog environment in which the BT-S910 entry appears.

Reference Standard: Relevant dimensional, thread, material, finish, and mechanical-performance standards should be identified only after the intended thread system and additional product characteristics are confirmed.

Garage Door Track Bolts: The BT-S910 Record

The strongest starting point for a BT-S910 inquiry is the catalog record itself. It establishes four useful facts:

• Product type: Track Bolt
• Model: BT-S910
• Specification: M6×16
• English size: 1/4″×5/8″

These fields are valuable because they establish a repeatable identity for the item. A buyer can reproduce them in an internal database, quotation request, purchasing note, inspection document, or supplier discussion without adding technical properties that have not been published.

The distinction between a verified field and an assumed field matters. “Track Bolt” is a verified product description. BT-S910 is a verified model identifier. M6×16 and 1/4″×5/8″ are verified catalog size labels. By contrast, the available evidence does not specify the bolt’s base material, surface finish, strength grade, thread pitch, tolerance, head configuration, drive style, mating component, or exact mounting position.

A clean sourcing record therefore does not need to become a detailed engineering drawing. Its first job is to preserve the identity the catalog actually provides.

This approach is especially useful when data passes through multiple systems. A catalog entry may be copied into a spreadsheet, ERP system, purchasing platform, quotation sheet, warehouse description, or customer email. If one department records only “M6×16” while another records only “1/4″×5/8″, the organization may unintentionally create duplicate records for what the catalog presents as one BT-S910 item.

Preserving the model number alongside both labels reduces that ambiguity.

M6×16 and 1/4″×5/8″: Keep Both With BT-S910

The most important feature of the BT-S910 record is not simply that it contains two dimensional expressions. It is that both expressions appear in the same catalog-listed product record.

That changes how the information should be normalized.

A useful internal record can be written as:

This structure preserves the catalog hierarchy. The model remains the product identifier, while the metric and inch expressions remain associated size fields.

The opposite approach can create avoidable confusion. Consider a purchasing database that receives the information but stores “M6×16 Track Bolt” as one product and “1/4″×5/8″ Track Bolt” as another. Unless additional supplier evidence establishes two separate items, that split would go beyond what the catalog supports. The source record points back to a single model: BT-S910.

At the same time, buyers should not reverse the logic and conclude that M6×16 and 1/4″×5/8″ are universally interchangeable dimensional definitions for bolts in general. The catalog association is specific to this product record. It does not establish a general engineering equivalence rule, a thread standard, or compatibility between unrelated bolts.

That distinction matters because nominal labels can carry different meanings in different hardware systems. The safe conclusion is narrow and useful:

For BT-S910 recordkeeping, retain both catalog size labels. For physical fit or interchangeability, request the additional technical information required by the application.

This is also why the model number should not be dropped from an inquiry. “M6×16 bolt” is a broader description than “BT-S910 Track Bolt, M6×16, English size 1/4″×5/8″.” The second version points directly back to the catalog record and leaves less room for product-identity drift.

The Size Labels Do Not Define Every Bolt Detail

The BT-S910 record is specific enough to identify the catalog-listed item, but it is not a complete manufacturing specification.

For example, M6×16 should not be expanded into an unsupported claim about thread pitch. The record confirms the written specification but does not provide a thread-pitch value. Likewise, the English size 1/4″×5/8″ should remain exactly what it is in the sourcing record: a catalog size field. It should not be used to infer a particular thread-per-inch value.

The same evidence boundary applies to other characteristics.

Thread and dimensional details

The available record does not establish the thread standard, pitch, dimensional tolerance, complete threaded length, shank geometry, or other detailed dimensions. If any of those characteristics determine whether the bolt will fit a particular assembly, they should become confirmation questions rather than assumptions.

Head and drive configuration

The product name “Track Bolt” does not by itself establish a specific head geometry or drive configuration. Buyers who require a particular head form, tool interface, or clearance envelope should request confirmation before treating those features as part of the BT-S910 specification.

Material and surface finish

No verified base material or finish is included in the available BT-S910 material-specification fields. It would therefore be inappropriate to describe the model as a particular steel grade, stainless fastener, galvanized bolt, plated bolt, or coated bolt without additional product evidence.

Strength and performance

The catalog size record does not provide a strength grade, tightening torque, proof load, tensile capacity, shear capacity, fatigue rating, corrosion result, lifecycle rating, or other performance value. Such properties can be important in hardware selection, but they should remain separate from the catalog-confirmed BT-S910 facts until supporting technical documentation is available.

Application-level compatibility

The word “Track” identifies the product category used by the catalog, but it does not establish universal compatibility with every garage door track, bracket, rail configuration, or door model. A buyer performing a garage door track repair should therefore avoid selecting the bolt solely because the nominal size appears familiar.

Fit depends on the actual mating parts and installation requirements. Those application details sit outside the current BT-S910 catalog specification and should be confirmed when they matter.

Build One Clear BT-S910 Inquiry Record

A useful BT-S910 inquiry begins by copying the verified information without alteration:

Product Type: Track Bolt
Model: BT-S910
Specification: M6×16
English Size: 1/4″×5/8″
Company: NINGBO BAOTENG TECHNOLOGY CO.,LTD

That five-field identity can function as the stable core of the request. Any additional requirements should be clearly separated into questions or buyer-defined requirements.

For example, if material matters to the application, the inquiry should ask the supplier to confirm the material instead of filling the field from assumption. If thread details matter, request the applicable thread standard and pitch. If the bolt has to match an existing assembly, provide the relevant assembly information and request compatibility confirmation.

This method protects both sides of a sourcing conversation. Buyers retain the published product identity, while suppliers can respond to missing technical fields without having to correct assumptions that were accidentally presented as catalog facts.

The same discipline is useful when information moves from inquiry to quotation and then to purchase order. The original fields should stay stable. Newly confirmed data can be appended as additional specifications rather than silently replacing or reinterpreting the catalog wording.

For buyers managing many hardware items, this distinction can prevent database duplication. One product should not become two purchasing records simply because one department favors metric notation and another favors inch notation. With BT-S910, the catalog itself provides a common identifier that can connect both descriptions.

It also prevents a different error: assuming that every superficially similar bolt belongs under the BT-S910 identity. A size match alone is not enough to establish model identity or compatibility. The model, product type, catalog size fields, and any separately confirmed technical requirements should be kept distinct.

The result is a more reliable record without inventing precision the source does not provide.
