SOURCING INSIGHT
Metal fasteners, hinges, and construction hardware are centered in Yongkang (Zhejiang province), alongside Haiyan (Zhejiang) for steel bolts and screws, and Wenzhou (Zhejiang) for door locksets and hardware. High mechanical loads require verification of metallurgical properties. MOQs typically range from 5,000 to 10,000 units per size, with sample lead times of 15 to 25 days. Quality control must focus on thread dimensional tolerances (Go/No-go gauges), tensile strength, carbon steel grade, and salt spray rust testing for zinc or nickel plating. Sourcing for construction use in the EU requires compliance with the Construction Products Regulation (CPR) and standard certifications such as EN 1935 for single-axis hinges and EN 12209 for locks.
What drives the price
Hardware pricing is driven by steel/brass raw material weight, heat treatment requirements, and plating thickness. Choosing standard thread sizes and carbon steel grades (e.g., Grade 8.8 or 10.9) keeps prices low, while custom molds, stainless steel (SUS 316), and heavy galvanization increase costs.
FREQUENTLY ASKED QUESTIONS
- How do you verify the rust resistance of zinc-plated fasteners?
- We perform a salt spray test (typically ASTM B117 / ISO 9227) ranging from 24 to 96 hours depending on the specified plating thickness to verify there is no red rust formation.
- What certificates must structural construction bolts have for the EU?
- Fasteners used in structural engineering must hold CE marking under EN 15048 (non-preloaded structural bolting assemblies) or EN 14399 (high-strength structural bolting assemblies for preloading).
- How do you prevent thread sizing issues in mass production?
- We enforce the use of calibrated Go/No-go thread ring and plug gauges during inline production and inspect dimensions against ISO 965 metric thread tolerances.
