Custom Reverse-Threaded Tapered-Head Bolts
Precision-Engineered Custom Bolts by Hetai
Hetai specializes in the manufacturing of Custom Reverse-Threaded Tapered-Head Bolts, designed for applications requiring special thread directions, unique head geometries, and reliable mechanical performance. These non-standard bolts can be manufactured according to customer drawings, samples, or specific application requirements.

Reverse Thread Design
The reverse-threaded design uses a left-hand thread configuration, making these bolts suitable for applications where conventional right-hand threads are not appropriate. The thread direction, pitch, diameter, and length can all be customized to meet specific assembly and operating requirements.
Precision Tapered Head
The tapered head is precision formed and machined to achieve the required geometry and smooth surface finish. Head diameter, taper angle, head height, and other dimensions can be customized according to technical drawings or samples.
Custom Manufacturing
Hetai supports a wide range of customization options, including:
- Reverse / left-hand thread
- Custom thread diameter and pitch
- Tapered or specially shaped heads
- Custom bolt length
- Customized head dimensions
- Special grooves, shoulders, and chamfers
- Various materials and surface finishes
Customers can provide 2D drawings, 3D models, samples, or technical specifications. Hetai’s engineering team can develop the appropriate manufacturing process based on the product structure and application requirements.
Materials & Surface Finishes
Depending on the application, these custom bolts can be manufactured from carbon steel, alloy steel, stainless steel, and other engineering materials.
Available surface treatments may include zinc plating, nickel plating, chrome plating, black oxide, electrophoretic coating, and other customized finishes.
