Established in 2006, Sinsun Hardware is a leading manufacturer and global supplier of high-quality fasteners. Operating from a gigantic 30,000 sqm integrated facility in Northern China, we run modern production zones, a 12,000 sqm smart warehouse (18,000+ pallet capacity), and multi-language customer support centers.
Our yearly output exceeds 8,500 containers, consistently servicing key global markets including the Middle East, Southeast Asia, South America, and Russia. We bring precision, material integrity, and large-scale operational control to the OEM cam lock nut manufacturing landscape.
As the modular furniture, consumer electronics, and automotive interior industries experience exponential growth, cam lock nuts have transitioned from simple woodworking components into critical mechanical structural fasteners.
Global demand for tool-free or rapid assembly mechanisms relies heavily on the dimensional stability of zinc-alloy and carbon steel cam lock nuts. They facilitate secure joints in particleboard and MDF panel systems.
Modern electrical enclosures and server racks require cam lock fasteners that resist loosening under prolonged motor or fan vibrations. Hardened materials and precise thread designs ensure long-term torque retention.
Cam lock structures provide rapid, blind-hole snap assembly for vehicle dashboards and internal panels, drastically reducing assembly line times while maintaining strict crash safety standard tolerances.
Our industrial OEM production capabilities guarantee extreme metallurgical precision, making Sinsun a trusted Tier-1 supply partner.

Our production capabilities are driven by German-imported multi-station cold heading machinery, precision Taiwanese machining lines, and a dedicated team of engineers. Sinsun offers over 20,000 SKUs of fasteners, each undergoing 12+ stringent quality checks.
From raw materials sourced from XING TAI Steel, we execute in-house spheroidizing annealing, wire drawing, cold-heading, thread-rolling, and advanced continuous heat treatment (supported by 4 newly added production lines in 2025). This ensures uniform microstructures and eliminates hydrogen embrittlement.
Sinsun established a production base in Northern China, focusing on self-tapping screw fabrication.
Established our global export department, expanding operations to Middle East and South American markets.
Added 4 spheroidizing annealing furnaces and wire drawing equipment for in-house material control.
Imported German multi-station cold heading machines to expand technical capabilities and fastener types.
Reached 36k tons of annual output and shipped over 1,100 standard export containers.
Optimized lead times by opening a 1,200 sqm ready-stock facility for emergency order fulfilment.
Commissioned 4 new high-capacity heat treatment lines, securing quality control and timely shipping.
Targeting Class-A emissions standards, European modular cabinet manufacturers require cam lock systems that prevent panel splitting under cyclic loading.
Sinsun Solution:We supply zinc alloy cam locks featuring internal rib patterns that secure into particleboard fibers without destroying panel core integrity.
Vibrational stress in recreational vehicles causes standard connectors to lose torque, leading to structure loosening during transit.
Sinsun Solution:We customize nylon-skirted self-locking cam lock nuts, combining metal load capacities with polymer vibration dampening.
Compact devices require sub-miniature cam locks with clean surface profiles to fit precise technical dimensions.
Sinsun Solution:We produce ultra-thin cam lock systems utilizing CNC turning centers, ensuring zero burr counts and Ra roughness levels below 0.3μm.
The industrial fastening sector is undergoing a rapid transition toward digital traceability, surface treatments with low environmental impacts, and automated visual sorting.
Transitioning standard cam locks to lightweight, high-performance composites and magnesium-aluminum alloys for EV weight reduction.
Linking cold-heading and heat-treatment control loops directly to ERP tracking systems for real-time quality and lead-time analysis.
Achieving zero ppm defect rates for automotive OEM components through automated sensor monitoring during assembly operations.
Every month, we welcome clients for on-site factory audits and production walkthroughs. Sinsun actively participates in international industrial exhibitions, showcasing our manufacturing advancements to build lasting distribution partnerships.
