Custom Stepped Eccentric Bolts – HETAI
HETAI manufactures custom stepped eccentric bolts engineered for precision positioning, alignment, adjustment, and mechanical fastening applications. Featuring a multi-step shaft, eccentric geometry, and integrated flange design, these bolts can be customized to meet specific dimensional and functional requirements.

Manufactured using precision CNC turning and machining processes, HETAI can produce stepped eccentric bolts according to customer drawings, samples, or application requirements. Critical dimensions such as eccentricity, step diameters, shaft lengths, thread specifications, flange dimensions, and tolerances can be customized.
Key Features
- Stepped Shaft Design: Multiple shaft diameters provide precise positioning and controlled mechanical engagement.
- Eccentric Geometry: The offset shaft allows controlled positional adjustment and alignment.
- Integrated Flange: The flange provides a defined seating surface and helps control installation depth.
- Precision Machining: CNC turning and secondary machining ensure accurate dimensions and consistent quality.
- Custom Threading: Metric, inch, fine, coarse, or application-specific threads are available.
- Custom Dimensions: Diameter, length, eccentricity, step configuration, flange size, and tolerances can be manufactured according to drawings.
- Multiple Materials: Stainless steel, carbon steel, alloy steel, aluminum, titanium, brass, and other engineering materials are available.
Manufacturing Capability
HETAI specializes in custom non-standard fasteners and precision CNC-machined components. Our production process can include CNC turning, milling, drilling, tapping, threading, thread rolling, grinding, and surface finishing.
Each custom stepped eccentric bolt can be manufactured according to the customer’s technical drawings or physical samples. Before mass production, HETAI can provide samples for dimensional and functional verification.
