Yes. Manufacturers can produce non-standard threads for custom fasteners, provided that the thread geometry, dimensions, tolerances, and application requirements are clearly defined. At HETAI, we manufacture custom bolts, screws, studs, nuts, threaded shafts, and other special fasteners with non-standard thread configurations based on customer drawings, samples, or technical specifications.

Non-standard threads are often required when a standard thread cannot meet the mechanical, dimensional, assembly, or functional requirements of a particular application. Instead of modifying an existing standard component, a manufacturer can produce the thread specifically according to the customer’s design.

What Is a Non-Standard Thread?

A non-standard thread is a thread that does not completely follow a commonly used standard specification. It may have a special diameter, pitch, profile, thread length, tolerance, or combination of these features.

For example, a customer may require a thread with an unusual pitch, a special major diameter, a partial threaded section, or a customized thread profile. The component may also require different thread specifications on each end.

Non-standard threads can be used in machinery, automotive components, industrial equipment, special tooling, hydraulic systems, electronic equipment, and replacement parts where standard fasteners are unsuitable.

What Types of Non-Standard Threads Can HETAI Produce?

Depending on the product design and production requirements, HETAI can manufacture various customized thread configurations, including:

• Special thread diameters
• Custom thread pitches
• Partial or specific thread lengths
• Special internal or external threads
• Different threads on opposite ends
• Modified thread profiles
• Fine or coarse pitches outside standard combinations
• Custom thread tolerances and fits
• Threads combined with shoulders, grooves, holes, steps, or special heads

For particularly complex thread designs, a detailed engineering drawing is recommended. The drawing allows HETAI to accurately understand the required thread profile, dimensions, tolerances, and relationship between the threaded and non-threaded sections.

How Are Non-Standard Threads Manufactured?

The manufacturing process depends on the material, thread size, geometry, quantity, tolerance, and application.

For suitable high-volume products, thread rolling may be an efficient solution. Thread rolling forms the thread by plastically deforming the material rather than removing material. It can provide good thread consistency and surface characteristics when the design and material are suitable.

For low-volume production, prototypes, special geometries, or complex components, CNC machining can provide greater flexibility. CNC turning can produce customized external threads, while CNC machining and tapping processes can be used for internal threads.

Other processes may also be used depending on the design, including thread cutting, grinding, or specialized machining methods.

What Information Does HETAI Need?

To manufacture a non-standard thread accurately, HETAI normally needs a technical drawing or detailed specifications. Important information may include:

• Major and minor diameter
• Thread pitch
• Thread profile
• Internal or external thread
• Thread length
• Thread tolerance
• Thread fit
• Material
• Heat treatment
• Surface treatment
• Quantity
• Applicable inspection requirements

If the customer does not have a complete drawing, a physical sample may also help our engineers understand the required dimensions and configuration.

Why Choose Custom Non-Standard Threads?

Non-standard threads can provide an effective solution when standard fasteners cannot satisfy a specific design requirement. They can be integrated directly into a custom component, allowing the thread dimensions and geometry to match the mating part.

This is particularly useful for equipment maintenance, replacement parts, prototypes, specialized machinery, and applications with limited installation space.

HETAI Custom Thread Manufacturing

At HETAI, we understand that not every mechanical application can use standard thread specifications. Our manufacturing capabilities allow us to produce custom and non-standard threads according to customer drawings, samples, and technical requirements.

Whether you need a special pitch, unusual diameter, customized thread length, internal or external thread, or a completely unique thread configuration, HETAI can evaluate the design and recommend a suitable manufacturing process.

Our goal is to provide reliable custom Bu Lông Ốc Vít with consistent thread dimensions, appropriate tolerances, and stable manufacturing quality for each specific application.
