AI-Powered supplier vetting

SummaryThe supplier is a manufacturing-oriented fastener and precision-machining supplier rather than a professional technical or 3D software design provider. It offers broad customization, including sample-based, design-based, full, minor, and flexible customization, and operates more than 10 production lines with multiple machining and forming machines. Finished-product inspection instructions are uniformly followed, with quality assurance and raw-material traceability identified. However, the supplier has no written procedures or records for supplier-service assessment, corrective and preventive actions, or customer complaint handling. It has no overseas agents, branches, warehouse, showroom, or offline trade-show participation. Financial records are indicated for 2022–2024, but no assessable financial results are provided. Innovation evidence is limited: no new products were reported in the past year, although ODM services are available. No certification or customer-case evidence is provided.

After-Sales capabilityThe supplier has in-stock service capacity and states that quality assurance and raw-material traceability are in place. However, it has no written procedures or records for corrective and preventive actions or effective customer-complaint handling, and it has no overseas agents, branches, warehouse, or showroom, limiting documented after-sales support infrastructure.

R&D capabilityThe supplier reports no new products during the past year, no SDK availability, and no professional technical-supplier or 3D software-design capability. It does provide ODM services and has one year of total R&D engineer experience reported, but the overall evidence does not demonstrate strong ongoing innovation capacity.

Production capacityThe supplier operates more than 10 production lines and lists diverse forming, machining, drilling, grinding, and cutting equipment for nails, screws, bolts, and CNC parts. It reports in-stock capacity, one-month average lead times in both peak and off-season periods, uniformly followed finished-product inspection instructions, and 11 years of export experience. However, it lacks a valid manufacturing-capacity contract with associated subcontractors, so the evidence supports substantial production capability but not fully controlled outsourced capacity.

Customization capabilityThe supplier explicitly offers customization from samples, customization from customer designs, full customization, minor customization, and flexible customization. ODM service is also available, providing direct evidence of broad product customization capability despite the absence of 3D software design services.

Product Q&A

Q:Is the screw corrosion-resistant?

Yes. It offers high salt-fog resistance, with stainless steel option available, and is RoHS 2.0 & ELV compliant.

Q:Does the drive slip during installation?

No. The anti-slippage drive (cross recessed or customized) ensures reliable torque transmission without bit slipping.

Q:How does it perform under vibration?

Pre-applied adhesive (threadlocker) provides excellent anti-loosening performance, even after multiple installation and removal cycles.

Q:Is the surface durable and wear-resistant?

Yes -high wear resistance with robust black finishes (Blackening/Sandblasting QPQ/Black Zinc/ZnNiBlack) per ASTM D3170 for superior abrasion protection and long service life

Q:Can I get customized versions?

Absolutely. OEM/ODM full customization -size, head, drive, material, finish, heat treatment, and adhesive application all tailored to your needs.
