Composite functional structure:A three-in-one design of locating pin + anti-rotation groove + internal hexagonal sleeve, replacing the traditional multi-part combination solution with a single component.

Axial double-slot anti-reverse function:The middle section performs symmetrical milling of the double straight slots structure. After being embedded in the base material, it forms a positive torque transmission, completely eliminating the circumferential rotation.

Hexagon tool interface:The rear end adopts standard hex socket holes and is compatible with 2.5mm to 8mm specification wrenches for operation.

Stepwise load transition:Three different diameter designs, with stress gradually distributed, avoiding stress concentration caused by abrupt changes in cross-section.

Environmentally friendly blue-white galvanized coating:Zinc sulfate coating that complies with RoHS standards, with salt spray test lasting for ≥ 48 hours, meeting both anti-corrosion and conductive requirements

1. Full openness of structural parameters
The diameter of the locating pin, effective length, slot width and depth, internal hexagon specification, outer diameter of the sleeve, and other key dimensions can all be customized according to the drawings, breaking the limitations of standard part selection and perfectly matching your structural design.
2. Flexible selection of material and process
Various base materials such as carbon steel (4.8/8.8 grade), stainless steel (304/316), and brass can be chosen; surface treatments include galvanizing, nickel plating, blackening, Dacromet coating, PVD coating, etc., meeting the requirements of differentiated environments.
3. Integrated cost reduction and efficiency improvement:
Integrating the functions of positioning, anti-rotation, and connection into a single piece reduces the number of parts purchased by more than 60%, eliminates the cumulative tolerance of multi-part assembly, and makes BOM management more concise.
4. Universal design of tools
The internal hexagon interface is compatible with the existing standard wrench system, eliminating the need to configure dedicated tools for special fasteners, reducing the investment cost of tools on the production line.
5. Rapid prototyping and verification
Equipped with a CNC turning and cold stamping combined production line, the first sample can be delivered within 7-15 days, supporting small-batch trial production and verification before mass production, reducing development risks.
