How do you control quality during production?

We request our QC team to inspect every production link for each batch of goods. We can also provide you with MTC and mill certificates when the goods are finished.

Do you provide free samples?

For new customers, we provide free samples for standard fasteners, but the client pays the express charges. For old customers, we send free samples and pay the express charges ourselves.

Do you accept small orders?

Yes, we accept any orders. We keep lots of stock for Bolts, Nuts, Threaded Rods, and Washers, and can produce them quickly.

What is your delivery time?

Generally, if goods are in stock, we can deliver them within 15 days. If the quantity is 1-2 containers, the delivery time is 25-35 days.

What is your packing method?

Our packing is 20-25kg per carton, with 36 or 48 cartons per pallet (about 900kg per pallet). We can also produce customer logos on cartons or customize cartons according to requests.

What are your payment terms?

We accept T/T, L/C, and D/P for general orders, and PayPal and Western Union for small orders or sample orders.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier and operates as a combined company involved in producing and selling fasteners, hardware products, auto parts, and oil pipeline fittings. It supports extensive product customization, including samples, designs, full customization, minor customization, and flexible customization. The supplier reports two production lines and one presence in a main export market, with an average lead time of one month in both peak and off-season periods. However, it lacks 3D software design services, SDK availability, in-stock capacity, overseas warehouses, overseas agents or branches, and offline trade-show participation. Finished products are checked by packing staff, while no written procedures or records are used for assessing service capability. The provided information does not establish certifications, financial strength, after-sales performance, or customer case history.

Supplier typeThe supplier is explicitly identified as a professional technical supplier. It is a combined company whose stated business scope includes production and sales of fasteners, hardware products, auto parts, and oil pipeline fittings, as well as related import and export activities.

R&D capabilityThe supplier is identified as having professional technical research and development capability, and it offers multiple forms of customization. However, it explicitly does not provide 3D software design services and has no available SDK, so the evidence supports technical customization but not broader digital or software innovation capability.

Production capacityThe supplier reports two production lines, one-month average lead times in both peak and off-season, and six years of exporting experience. Countervailing controls are limited: finished products are checked by packing staff, there is no continuous quantity reconciliation for each batch or production run, no outsourcing SOP, no valid manufacturing-capacity contract with related subcontractors, and no in-stock capacity.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad product-design and modification capability, although 3D software design services are not available.
