Custom High Head Shoulder Step Bolts – Hetai
Hetai specializes in manufacturing custom high head step bolts for applications that require special head dimensions, stepped shafts, precise positioning, and reliable mechanical fastening. Manufactured according to customer drawings, samples, or specifications, our custom step bolts are suitable for machinery, automotive components, industrial equipment, fixtures, and precision assemblies.
High Head and Stepped Shaft Design
A high head step bolt combines a raised bolt head with a stepped or shoulder shaft design. The higher head provides additional material for specialized clamping and positioning requirements, while the stepped shaft can provide accurate spacing, alignment, and component positioning.
The step dimensions, shoulder diameter, shaft length, thread length, and head geometry can all be customized according to the application.
Precision Custom Manufacturing
Hetai manufactures non-standard step bolts using CNC turning, automatic lathe machining, cold heading, thread rolling, drilling, milling, and other precision manufacturing processes.
Depending on the design and production volume, we can select the appropriate machining process to achieve dimensional accuracy, consistent threads, and stable production efficiency.
Custom options include:
- High or extended head designs
- Single-step or multi-step shaft configurations
- Custom shoulder diameters
- Different thread sizes and pitches
- Customized overall lengths
- Partial or full-length threads
- Special head shapes
- Internal or external drive features
- Chamfering and precision turning
- Custom surface treatments
Materials
Hetai can manufacture custom high head step bolts from a wide range of materials, including:
- Carbon Steel
- Alloy Steel
- Stainless Steel
- Brass
- Aluminum Alloy
- Titanium Alloy
Material selection can be optimized according to requirements for strength, corrosion resistance, weight, machinability, electrical conductivity, and operating environment.
Surface Finishing
To meet different application requirements, custom step bolts can be supplied with various surface finishes, such as:
- Zinc Plating
- Nickel Plating
- Chrome Plating
- Black Oxide
- Passivation
- Electrophoretic Coating
- Anodizing
- Polishing
- Natural Metal Finish
Applications
Custom high head step bolts are commonly used in:
- Industrial machinery
- Automotive components
- Mechanical equipment
- Electrical equipment
- Automation systems
- Precision fixtures
- Mounting and positioning assemblies
- Structural components
- Custom mechanical assemblies
The stepped shaft is particularly useful when the fastener must perform both fastening and positioning functions within an assembly.
