AI-Powered supplier vetting

SummaryThe supplier is a limited company producing fasteners and related components, including threaded rods, bolts, nuts, screws, washers, brackets, and end connectors. It reports substantial stated annual production volumes and has invested in cold-heading, threading, galvanizing, heat-treatment, and automated conveyor equipment. It supports extensive customization and 3D software design services, but reports no new products in the past year, no SDK, and no status as a professional technical supplier. Service procedures for corrective actions and complaints are documented and followed, while service assessment procedures lack records. The supplier has participated in Hannover Messe 2025 but has no overseas showroom, agents, branches, or overseas service locations. No certifications, customer cases, or verified financial-credit information are provided.

Supplier typeThe supplier is identified as a limited company with five employees and no parent-group affiliation. Its product scope is centered on fasteners and related hardware, including bolts, nuts, screws, brackets, and end connectors, indicating a specialized product manufacturer rather than a diversified corporate group.

After-Sales capabilityThe supplier states that it provides a strong after-sales guarantee, and it has clear, followed procedures for corrective and preventive actions and customer complaints. However, it lacks overseas showrooms, agents, branches, and overseas service locations; its general service-assessment procedure exists but has no records.

R&D capabilityThe supplier provides 3D software design and ODM services, but reports no new products in the past year, no available SDK, and only one year of total R&D-engineer experience. It also identifies itself as not being a professional technical supplier, so innovation capability is mixed and not strongly evidenced.

Production capacityThe supplier reports annual capacities of 9,000 tons of threaded rods, 2,500 tons of bolts, and 3,000 tons each of nuts, screws, and washers. It has 60 cold-heading and threading machines, two galvanizing lines, two heat-treatment lines, and automated conveyor belts; reported lead time is one month in both peak and off-seasons, supporting a positive production-capability assessment.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and it provides 3D software design services. These statements directly support broad customization capability.

Product Q&A

Q:Q1: What types of slider nuts do you have?

A: We have two main types: ball spring sliding nuts (fast installation) and traditional T-type slot nuts (heavy load). Full specifications from M3 to M8 for 20/30/40/45 aluminum profiles are available.

Q:Q2: What is the difference between galvanized carbon steel and 304 stainless steel?

A: Galvanized carbon steel is cost-effective, suitable for indoor dry industrial environments. 304 stainless steel is anti-rust, anti-corrosion, perfect for outdoor, food machinery, chemical and humid workshop.

Q:Q3: How to choose the right size?

A: Confirm your aluminum profile series first (20/30/40/45). Each profile corresponds to exclusive nut width and height. We provide size chart and free size matching service.

Q:Q4: Can I install the nut without cutting the profile?

A: Yes. Ball spring slider nuts can be inserted directly from the middle of the profile slot without disassembling or cutting the profile, very suitable for secondary installation and equipment modification.

Q:Q5: Do you support custom service and OEM?

A: Yes. We support custom size, thread, surface treatment and logo printing. Samples are available for quality checking before bulk order.
