We support trial orders from as low as 100 pieces for stock items, with LCL consolidation available for mixed SKUs. Factory production runs typically start from 500kg-1 ton per size depending on diameter -- far below the 5-20 ton minimums most Chinese factories demand directly.

Yes. Send STEP, DWG, DXF, or PDF files through the upload area above. Our bilingual application engineers return a DFM assessment within 24 hours -- including cold-heading tolerance optimization that typically reduces machining cost by up to 25%. Custom tooling lead time is 10-15 days, with rapid samples before mass production.

Every lot passes a 5-stage defense: raw-material spectrometer verification, first-article dimensional inspection, optical sorting to AQL ≤ 0.65, Rockwell hardness testing, and ASTM B117 salt-spray validation. Each shipment ships with lot-number traceability to the steel billet, EN 10204 3.1 MTR, and pre-shipment photos -- plus a replacement/compensation warranty for any verified non-conformity.

New accounts: 100% T/T for samples or 30% deposit + 70% balance before shipment (against QC photos and inspection report). Irrevocable L/C at sight is accepted for container-volume orders. PayPal and Alipay are available for small sample payments. We do not offer OA credit terms on first transactions -- established accounts may qualify for extended terms after trade history is built.

That is our core advantage. Factories only manufacture their single specialized category -- we combine screws, bolts, nuts, washers, and anchors from 3-5 partner factories into one container, one bill of lading, one invoice. Both FCL and LCL consolidation ship from Tianjin Xingang Port, just 35km from our warehouse.

Quotations with landed FOB/CIF pricing, packaging specs, and lead times are delivered within 24 hours, Monday to Saturday. Stock samples dispatch within 48 hours free of charge (courier freight collect or credited against your first order). New-production samples take 7-15 days depending on tooling requirements.

We operate under ISO 9001:2015 and supply full documentation packs: EN 10204 3.1 Mill Test Reports, Certificate of Origin, dimensional inspection reports, salt-spray and hardness test data, PPAP Level 3 for automotive programs, and EU CBAM-ready carbon emission records for stainless shipments. All customs documentation for your destination market is handled by our export team.
