Product Overview & Advantages

In non-standard automation and precision molds, the loosening or wear of fasteners and locating pins is often the primary cause of equipment downtime. Allied Metal manufactures custom fasteners specifically engineered to withstand high-frequency vibration and demanding insertion cycles:

Core Advantages

Excellent Anti-loosening & Wear Resistance

Custom thread tolerance fits, pre-applied thread-locking adhesive, or retaining ring grooves, combined with hardening treatment, significantly extend service life.

Strict Batch Consistency

Produced using high-precision Swiss-type lathes, ensuring dimensional tolerances and surface finishes of every single pin in your batch are identical.

Precision Cold Heading & CNC Hybrid Process

Combining the efficiency of cold heading with the precision of CNC turning. Ensures dense internal metal grain flow while meeting tight tolerances and reducing overall costs.

Full Material Traceability

From raw material certificates (MTC) to heat treatment and electroplating, a complete traceability system is established to ensure compliance with industrial standards.

Fastener Customization Process

Requirement Analysis

Provide drawings or samples, specify materials and surface finish requirements.

Process Evaluation

Engineers evaluate turning/cold heading processes to provide cost-reduction solutions.

Material Prep & Sampling

Procure custom materials and start sample machining and testing.

Sample Approval

Send samples for dimensional and mechanical performance testing.

Mass Production

Strictly control batch consistency and deliver on time.

Strict QC: Zero Tolerance for Loose Screws

We guarantee zero-defect components. Every batch undergoes rigorous dimensional and mechanical verification using CMM, optical comparators, and hardness testers to ensure it meets or exceeds your design standards.

FAQs

Yes. We are proficient in CNC turning and cold heading, capable of customizing various irregular structures (such as special thread pitches, flat heads, hex sockets, etc.), and can find solutions for unconventional materials.

It depends on the process. Standard black oxide is about 24-48 hours; zinc plating or Dacromet can reach 72 hours to over 500 hours. Our engineers will recommend the most cost-effective anti-rust solution based on your operating environment.

We use high-precision Swiss-type lathes and automatic turning machines to minimize human error. First article inspection, in-process inspection, and final inspection are conducted for every batch. For critical dimensions, we use 100% CCD sorting equipment for screening.

Absolutely. Whether it’s 1 piece or 100 pieces, we are willing to support your R&D progress by providing 7-10 days rapid prototyping services to help you validate your design quickly.
