What are the bolt placement and bolt spacing requirements?

The bolt arrangement can be divided into parallel and staggered arrangements. The parallel bolt arrangement is simple, neat and compact, and the size of the connecting plate used is small, but the cross-section of the component is greatly weakened; the staggered bolt arrangement is not compact, the size of the connecting plate used is large, and the cross-section of the component is weakened. Less stress.

AI-Powered supplier vetting

SummaryThe supplier is a limited-company trading company with 15 employees and a valid import/export license. It reports 90% export sales, flexible customization, ODM services, OEM experience for popular brands, in-stock capability, quality assurance, and raw-material traceability. Customer-oriented delivery and after-sales service are claimed, but supporting records are incomplete for corrective actions and complaint handling. The supplier has no available SDK, no new products in the past year, and no overseas agents, branches, warehouses, showrooms, or offline trade-show participation. Manufacturing outsourcing procedures and contracts are not confirmed. Financial information identifies reporting years but provides no substantive financial results, so financial credibility cannot be assessed. Customer reach is described as more than 382 customers, although specific customer cases are not provided.

Supplier typeThe supplier is identified as a limited company and a trading company, with 15 employees, no parent-group affiliation, and a valid import/export license. This supports classification as an independently operated trading supplier rather than a confirmed manufacturer.

CertificationsThe supplier explicitly reports holding a valid import/export license. No other certification information is provided, so the assessment is limited to this documented license.

R&D capabilityThe supplier has no available SDK and reports no new products during the past year, indicating limited documented product-development activity. It does provide ODM services, but this alone does not establish strong internal innovation capability.

Customization capabilityThe supplier explicitly offers flexible customization and ODM services, and also reports OEM service for popular brands. These statements provide direct evidence of customization and externally oriented design-manufacturing support.
