Custom Non-standard Cold Heading Fasteners Precision YONGMAO

When your engineering designs call for specialized fastening solutions that standard products cannot fulfill, YONGMAO provides a comprehensive custom manufacturing service. We specialize in producing Custom Non‑standard Fasteners through advanced cold heading, cold forging, and cold forming technologies—a near-net-shape manufacturing process that transforms wire coils into high-precision components with exceptional material efficiency and consistent mechanical properties. This approach minimizes secondary machining, reduces production costs, and accelerates your time-to-market.

YONGMAO has earned its reputation as a premier China fastener manufacturer through over 30 years of continuous operation and technical innovation. Our expertise is validated by dozens of invention patents and our 2023 designation as a High-Tech Enterprise. We have accumulated unparalleled technical mastery in three critical areas: ultra-deep hole drilling, ultra-slender part machining, and high-head-ratio forming. These specialized capabilities have redefined industry standards, enabling our customers to achieve superior product quality, enhanced safety, and greater production stability. Our manufacturing facility is equipped with fully automatic multi-station cold heading machines (including SJBP-256LL, SJBP-255L, and SR-136LL models) and thread rolling equipment, supported by CNC machining centers for comprehensive production flexibility.

Our Cold Heading Process delivers components with superior grain structure and enhanced strength through work hardening—advantages that cannot be achieved through conventional machining or red-hot forming. The one-step forming capability produces complex geometries with tight dimensional tolerances, often replacing traditional turning and red-hot forging processes while improving material utilization and reducing energy consumption. We work with a diverse range of materials including stainless steels, aluminum alloys (7075, 6066), and alloy steels (10B21, 20CrMo) to meet your specific strength, weight, and corrosion resistance requirements.

Quality assurance is fundamental to our operations. As an ISO9001 Certified Manufacturer since 2006, we maintain comprehensive in-process quality control supported by our re-equipped laboratory featuring salt spray testers, tensile testing machines, magnetic particle flaw detectors, metallographic analyzers, Rockwell hardness testers, projectors, and torque testing equipment. Every production batch undergoes rigorous inspection to verify dimensional accuracy, mechanical properties, and surface integrity. Our commitment to quality has earned the trust of partners including automotive suppliers and manufacturers in the agricultural machinery, high-speed rail, and construction equipment sectors.

YONGMAO is dedicated to creating value through engineering excellence, responsive service, and dependable product quality. We provide end-to-end support from design consultation to prototyping and large-volume production. Partner with us to optimize your fastening solutions and gain a competitive advantage in your market.
