Custom 1000mm Extra-Long Fully Threaded Socket Head Bolts | HETAI Manufacturing
Product Overview
HETAI Manufacturing specializes in the production of Custom 1000mm Extra-Long Fully Threaded Socket Head Bolts, designed for applications requiring exceptional length, precise threading, and reliable mechanical performance.
Featuring a cylindrical socket head with an internal hex drive and a fully threaded shaft, these extra-long bolts provide secure fastening and convenient installation in deep or extended assemblies. With a custom length of up to 1000mm, or according to customer drawings, they are suitable for specialized machinery, structural assemblies, industrial equipment, and other applications where standard fasteners are not long enough.
As a professional custom fastener manufacturer in China, HETAI provides complete manufacturing solutions for non-standard bolts according to drawings, samples, material specifications, thread requirements, and application conditions.
Key Features
- Extra-Long Length – Custom lengths up to 1000mm and beyond can be manufactured according to requirements.
- Fully Threaded Shaft – Continuous external threading provides flexible engagement along the entire shaft.
- Socket Head Design – The cylindrical head with an internal hex socket allows efficient torque transmission and installation in confined spaces.
- Custom Thread Specifications – Diameter, pitch, thread class, and thread length can be customized.
- Precision Machining – CNC turning and other precision machining processes ensure dimensional accuracy.
- Non-Standard Design – Suitable for applications requiring special lengths or dimensions unavailable from standard fasteners.
- Custom Materials & Finishes – Various steels, stainless steels, and surface treatments are available.

Manufacturing Process
Producing a 1000mm-long precision threaded fastener requires appropriate equipment, process control, and inspection throughout production.
HETAI’s manufacturing process may include:
Raw Material Selection → Cutting → CNC Turning → Thread Machining/Rolling → Socket Head Machining → Straightness Control → Dimensional Inspection → Surface Treatment → Final Quality Inspection → Packaging
For different diameters, materials, thread specifications, and production volumes, HETAI engineers can select the appropriate manufacturing process to balance precision, production efficiency, and cost performance.
Applications
Extra-long fully threaded socket head bolts are commonly used in applications where extended fastening length or deep thread engagement is required, including:
- Industrial machinery
- Large mechanical assemblies
- Automation equipment
- Mold and tooling systems
- Construction equipment
- Structural assemblies
- Equipment frames
- Heavy-duty machinery
- Customized engineering projects
- Specialized maintenance and repair applications
Quality Control
For long, precision-machined fasteners, dimensional consistency and straightness are particularly important. HETAI performs inspections throughout the manufacturing process to verify critical dimensions and thread quality.
Depending on customer requirements, inspection can cover:
- Overall length
