AI-Powered supplier vetting
SummaryThe supplier demonstrates established export experience, with 90% of sales from exports and 22 years of exporting. It has ISO9001:2015 certification, raw-material traceability, quality assurance, and 100% finished-product inspection, although inspection is performed by packing staff and only two quality inspectors are reported. Customization is broad, covering samples, designs, full customization, minor customization, and flexible customization. Service strengths include in-stock capability, stated lead times within 15 workdays in both peak and off-season, and multiple payment and quotation terms. Limitations include no overseas warehouse, showroom, agent, branch, or overseas service-country coverage, no Fortune 500 cooperation, no new products launched in the last year, one R&D engineer, no popular-brand OEM, and an undocumented corrective/preventive-action process. Financial credibility cannot be assessed because the provided financial figures are excluded from evaluation.
Supplier typeThe supplier is strongly export-oriented, reporting 90% export sales and 22 years of export experience. It can provide in-stock service and accepts FOB, CIF, CFR, and EXW terms, but reports no overseas warehouse, showroom, agent, branch, or overseas service-country coverage.
CertificationsThe supplier reports an ISO9001:2015 certificate for both sustainable development management and management systems, plus other product compliance or sustainability certifications. The specific additional certifications are not identified, so the evidence supports ISO9001 holding but not broader certification strength.
R&D capabilityThe supplier reports one R&D engineer and no new products launched during the previous year. It also reports no available SDK and no popular-brand OEM capability, which indicates limited documented innovation evidence.
Production capacityProduction-related evidence includes raw-material traceability, 100% finished-product inspection, quality assurance, four own-brand quality-control capabilities, inventory capacity, and lead times within 15 workdays in both peak and off-season. Only two quality inspectors are reported, and finished products are checked by packing staff, so production capability is positive but quality-control depth is limited.
Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization capability.
Product Q&A
Q:Do these cut-tail wood screws need pre-drilling?
A:
Pre-drilling is typically unnecessary for most wood substrates (softwood, plywood, MDF, OSB). The cut-tail tip smoothly cuts wood fibers. For dense hardwood (oak, teak) or boards over 30mm thick, a pilot hole (70-80% of shank diameter) is advised to prevent splitting or screw breakage.
Q:What are the differences between 304 and 316 stainless steel?
A:
304 stainless steel suits most indoor and general outdoor environments, offering good corrosion resistance at a lower cost. 316 stainless steel, with added molybdenum, excels in salt spray resistance, ideal for coastal or highly corrosive settings.
Q:What is the advantage of a cut-tail screw over standard wood screws?
A:
The cut-tail tip cuts wood fibers rather than pushing them aside, reducing driving torque and preventing splitting, especially in hardwood. It also ensures tighter thread engagement for enhanced holding power.
Q:What sizes and lengths are available?
A:
Sizes range from ST2.2 to ST6.3, with lengths from 4.5mm to 50mm.
Q:What certifications does the product have?
A:
The product meets DIN 7982f standards and comes with a Material Test Certificate.
