Custom Fastener Service
We not only supply standard fasteners, but also support customization based on samples, drawings, and application requirements, with adjustments available for key aspects such as head type, material and surface treatment, size specifications, and packaging labels.
What Can Be Customized
- Confirm head type structure based on samples or drawings
- Match the head type to the installation position and tool engagement method
- Adjust the standard design into a head type solution that better fits project assembly needs
- Select suitable materials based on the application environment
- Match the appropriate surface treatment according to corrosion resistance requirements
- Take purchasing positioning, usage requirements, and delivery consistency into account
- Adjust length and diameter based on existing components and installation conditions
- Optimize and confirm specifications based on standard sizes
- Support drawing-based specification customization requirements
- Support adjustments to inner packaging, outer carton packaging, and packaging formats
- Support customization of labels, barcodes, carton marks, and project identification information
- Suitable for OEM, brand customers, project orders, and regular export supporting needs
Custom Process
From requirement confirmation to mass production, our custom process helps turn samples, drawings, and specification requirements into clear and workable fastener solutions.
Requirement and Information Confirmation
After receiving the sample, drawing, specification, or application information, we first confirm the head type, material, surface treatment, size, and packaging requirements.
Custom Solution Confirmation
Based on the available information, we further confirm the workable customization solution, including product structure, key dimensions, material direction, surface treatment method, and packaging requirements.
Sample / Pilot Production Verification
Samples or pilot production are used to verify the head structure, size matching, surface treatment effect, and packaging or labeling details, helping reduce later adjustment risks.
Mass Production and Delivery
After confirmation, mass production is arranged according to the approved solution, with packaging, labels, carton marks, and shipping information implemented at the same time to keep delivery consistent with the confirmed requirements.
Raw Material Sourcing & Inspection Process
Raw materials are sourced according to product requirements and order needs, and incoming materials are first confirmed by batch before entering production.The inspection mainly covers basic specifications, surface condition, batch information, and incoming material consistency. Only after no obvious abnormalities are found will the materials move on to the next production stage.
During raw material management, we keep corresponding batch records and ensure that incoming material information remains linked to subsequent production and inspection records.This allows clearer batch traceability, quality review, and follow-up confirmation during order execution.
Finished Product Inspection
After production is completed, we further confirm dimensions, threads, appearance, and related performance according to product requirements, ensuring the finished products remain consistent with the confirmed requirements and are suitable for subsequent use and delivery.
Drilling Test
For products with specific dimensional requirements, we carry out dimension tests to confirm whether the key dimensions meet the corresponding requirements.
For products that require connection strength verification, we perform tensile tests to confirm basic reliability under load conditions.
This test helps evaluate the load-bearing performance of the product in actual fastening applications and further confirm the consistency of bulk products.
For products with surface treatment or corrosion resistance requirements, we inspect the surface and coating condition according to the specific requirements.
