Quality First

Thread Profile & Closure Quality Control

Threaded nozzles, screw caps and matching components should be checked as a complete closure assembly. Dimensional consistency, thread profile, surface finish and component fit can be reviewed during production and sampling.

Thread Profile Control

Key dimensions and thread geometry can be checked against the approved drawing, sample or matching closure components.

Closure Component Matching

Cap, nozzle, liner and inner-cap combinations should be evaluated together according to the container opening and required closure structure.

Surface Finish Options

Tin-plated steel, selected coated finishes and printed cap options are available on applicable models and projects.

Dimensional Inspection

Inspection can include fitting diameter, cap dimensions, thread profile, finish and assembly fit according to the agreed specification.

What to Confirm Before Production

For replacement or custom threaded closures, provide enough information to compare the complete interface between the can opening, nozzle, cap and sealing components.

Container Opening

Opening diameter, neck or flange profile and relevant can dimensions.

Thread & Cap Dimensions

Thread profile, cap height, outer diameter and any matching sample measurements.

Liner / Inner Cap

Required liner, metal inner lid or plastic inner-cap structure and material specification.

Drawing or Sample

Clear photos, technical drawings or a physical sample help reduce ambiguity during matching.

Applications for Threaded Metal Can Closures

Threaded nozzles and screw caps are used across industrial container projects where opening dimensions, thread profile, liner choice and material requirements need to be matched.

Lubricants & Industrial Oils

For lubricant and industrial-oil packaging projects, confirm the can opening, thread profile, liner or inner-cap structure and material requirements.

Paints & Coatings

For paint, coating and ink packaging projects, provide the opening dimensions, cap series, liner requirement and any applicable storage or compatibility requirements.

Food & Ingredient Packaging

For food or ingredient packaging projects, provide the required material and compliance standard so the suitable cap, liner and inner-seal specification can be confirmed.

Chemicals

For industrial chemical packaging projects, confirm material compatibility, closure dimensions and any applicable storage or transport requirements for the complete container system.

Home Care & Daily Chemical

Closure components can be evaluated for detergent, cleaner and household-product packaging according to the container opening, material and required component combination.

Specialty Packaging

Selected coated and printed cap options can be evaluated for specialty packaging projects where appearance and closure configuration are part of the specification.

OEM & Custom Support

OEM Threaded Nozzles, Screw Caps & Liners

For projects that do not match the standard series, custom threaded nozzle, screw cap and liner combinations can be evaluated from your can dimensions, thread profile, drawing, sample and order requirements.

Custom Size & Thread Profile

Non-standard diameters and thread profiles can be evaluated from drawings, dimensions or matching samples.

Liner & Inner-Cap Matching

Available liner, metal inner-lid and plastic inner-cap options can be compared according to the required closure structure.

Printed Cap & Finish Options

Printed cap artwork and selected surface-finish options can be evaluated according to the applicable model and order requirements.

Sample-Based Matching

Existing nozzles, screw caps or complete closure samples can be measured and compared with standard or custom options.

Threaded Nozzle & Cap Sourcing FAQs

Key questions for matching thread size, profile and sealing components.

What threaded nozzle sizes are available?

The current range covers 18mm, 30mm, 32mm, 42mm, 47mm, 55mm and 70mm series, including selected low- and high-profile thread designs. Exact fit should be confirmed from the can opening and thread dimensions.

Which liner or inner cap should I use?

The suitable option depends on the container, filling product, closure structure and sealing process. Share your current assembly, material requirement or sample so available liners, metal inner lids and plastic inner caps can be compared.

Can you match an existing screw cap or nozzle?

Yes. Provide the opening diameter, thread profile, cap height and clear photos, drawings or a physical sample. Sampling can be discussed when dimensional confirmation is required.

What is the difference between low- and high-profile threaded caps?

They use different cap heights and thread geometries. Do not select by diameter alone; compare the thread profile, nozzle shape, cap height and matching inner components with your existing closure.

What information should I send for a threaded closure quotation?

Please provide the can opening diameter, thread profile, cap or nozzle dimensions, liner or inner-cap requirement, material or finish requirements and order quantity. Drawings, photos or samples are welcome.
