Stainless Steel Custom Bolt ball head bolts

This series of stainless steel non-standard customized shaft components are one-piece carved non-standard fasteners specially designed for special working conditions in equipment, machinery, tooling, etc. They cover two core structures:

Ball head bolt: The top is a smooth hemispherical structure, combined with a hexagonal transition shoulder and standard threaded rod body, featuring both connection and universal / guiding functions;

Step shaft shoulder bolt: The hexagonal head + step positioning shoulder + standard threaded rod body are integrated in one design, enabling precise axial positioning and locking of components.

The product is made of high-quality 304 stainless steel, formed by CNC machining as a single piece, with a smooth and clean surface without burrs. The dimensional accuracy can reach ±0.01mm, and the threads are processed by precise rolling, with regular tooth profiles and strict tolerance control. They are perfectly compatible with standard nuts, have tight engagement without slippage, and are the dedicated core fasteners for customized connections and positioning in industrial equipment, tooling fixtures, and mechanical transmission scenarios.

Core Structure：Various non-standard structures can be customized: ball head bolt (hemispherical top + hexagonal transition shoulder + threaded rod body), stepped shaft shoulder bolt (hexagonal head + stepped positioning shoulder + threaded rod body)

Material Configuration：304 stainless steel material, surface passivation treatment, native anti-rust and corrosion resistance, suitable for humid / outdoor / complex working conditions

Specification：Adaptation Diameter, length, thread specification, ball head diameter, stepped size can all be customized according to the drawing, and non-standard size processing is supported

Performance：High precision size tolerance, high strength tensile / shear resistance, corrosion resistance, suitable for precise assembly and special working conditions

Processing Technology：Integrated CNC turning, smooth surface without burrs, precise rolling processing of threads, stable engagement without slippage

Fully customized structure, suitable for special working conditions

Customized ball heads, steps, shoulder parts and other non-standard structures can be made according to customer drawings. Special functions such as universal guidance, axial positioning and component alignment can be realized as needed, perfectly adapting to the special installation space and functional requirements of equipment and tooling, without the need for additional secondary processing.

Stainless steel with inherent rust prevention, suitable for complex working conditions

Using 304 stainless steel material with a chromium content of 18%-20%, the surface is treated with passivation, resistant to salt fog, acid and alkali corrosion, not afraid of outdoor, humid, and coastal high humidity salt fog environment, long-term use does not rust or corrode, significantly reducing the later maintenance and replacement costs.

High-precision turning processing, strict control of size tolerance

The structure is formed by integrating with a CNC turning equipment, with a size accuracy of IT7 level, coaxiality and roundness errors are extremely small, thread accuracy reaches 6g level, suitable for equipment and tooling with assembly accuracy requirements, ensuring component assembly accuracy and operational stability.

Multi-structure and multi-functionality, suitable for different functional requirements

Ball head bolt: The hemispherical top can achieve universal guidance/connection, reducing component wear, suitable for transmission and guiding mechanisms;

Step shoulder bolt: The stepped positioning shoulder can limit axial displacement, achieve rapid and precise alignment of components, suitable for positioning locking requirements of molds and tooling;

One piece multi-purpose, simplifies equipment assembly process, reduces accessory types and inventory costs.

Integrated forming process, strong and durable

The shaft body is formed by turning integration, without welding or splicing, the rod body strength is uniform and stable, with excellent tensile and shear performance, long-term use is not prone to deformation or fracture, ensuring the operational safety of equipment and tooling.

Industrial equipment and mechanical transmission scenarios

Ball head bolts are used for adapting transmission mechanisms and guiding devices. The smooth hemispherical top reduces component wear and enables universal connection. The stainless steel material is suitable for humid and oily environments in workshops. Step shaft shoulder bolts are used for connecting machine tools and pump bodies to the frame. The step positioning shoulder realizes precise alignment of components, ensuring the stability of equipment operation.

Workholding and fixtures scenarios

Workholding and fixture positioning axes and connecting axes for automated production lines and assembly lines. Step shaft shoulder bolts can achieve rapid positioning and locking of workholding fixtures, ensuring high precision dimensions for repeated positioning accuracy of workholding fixtures. Ball head bolts are adapted for guiding/ supporting mechanisms of workholding fixtures, reducing wear of workholding fixtures and extending their service life.

Molds and workholding fixtures scenarios

Positioning pins and guide column accessories for stamping molds and injection molds. Step shaft shoulder bolts can achieve coaxiality control of molds. Stainless steel material is rust-proof and wear-resistant, reducing the frequency of mold maintenance; Ball head bolts are adapted for the guiding mechanism of molds, achieving smooth opening and closing and improving mold processing accuracy.

Outdoor and humid environment scenarios

Adapted for non-standard connections and positioning of outdoor equipment, photovoltaic support components, and garden machinery. Stainless steel material is resistant to salt fog, acid and alkali corrosion, and is not affected by sunlight and rain. It does not rust or loosen over a long period of use, reducing maintenance costs in the future.

General non-standard connection and positioning scenarios

Various scenarios requiring non-standard structural fasteners, such as pressure vessels, large equipment bases, and transmission component connections. They can be quickly customized according to customer drawings without additional secondary processing, simplifying the assembly process and adapting to personalized equipment requirements.
