High-Precision Fasteners, Cold Headed to Non-Standard Spec – YONGMAO
High-Precision Cold Headed Non-Standard Fasteners: custom parts cold-formed for high accuracy and consistent strength, ideal for automotive, e-bike and EV battery use.
YONGMAO specializes in tailor-made non-standard high-precision fastener fabrication, leveraging mature cold heading and cold forming technologies to cater to complex engineering requirements. Every finished part maintains tight dimensional tolerances, smooth surface quality and stable mechanical performance to fit harsh operating scenarios.
We master core processing capabilities including ultra-deep hole drilling, thin component turning and high head ratio forming. These technical strengths are backed by multiple invention patents and our high-tech enterprise accreditation awarded in 2023. Our production workshop is equipped with automatic multi-station cold heading machines and full-range CNC machining facilities to realize stable, traceable production management.
Holding ISO9001 certification, we enforce strict quality inspection across the whole production workflow. Our in-house testing lab is furnished with tensile test devices, hardness gauges, metallographic inspection instruments and torque testers for complete performance verification.
The cold forming method we adopt optimizes internal metal grain flow via cold work hardening, greatly boosting the structural robustness and long-term dependability of fasteners. If you pick YONGMAO as your supplier, you will get a reliable partner focused on precise customization, strict quality control and timely customer support.
