Key features

Manufactured according to DIN 982 High Type Lock Nut dimensional requirements, providing extended thread engagement and reliable fastening performance for demanding mechanical assemblies.

The integrated nylon ring of the Stainless Steel Nylon Insert Nut creates prevailing torque against the mating thread, helping reduce loosening caused by vibration and repeated movement.

The taller body of the High Profile Hex Lock Nut provides greater thread engagement than a low-type nylon lock nut, making it suitable for machinery, vehicles, and industrial equipment.

Made from corrosion-resistant stainless steel, this corrosion-resistant fastener is suitable for humid, outdoor, marine, and general industrial environments.

Customized OEM self-locking nuts are available with different thread sizes, pitches, nylon insert colors, material grades, markings, labels, and export packaging.

AI-Powered supplier vetting

SummaryNingbo Mianxuan Import & Export Co., Ltd. is identified as a China-based manufacturer/factory offering vehicle parts, CNC machining, stamping, casting, die-casting, fasteners, plastic, and rubber products. It reports TS 16949 and ISO 9001 certifications, more than 10 production lines, 6–10 quality-control staff, and shipment inspection reports with material certificates. The supplier provides 3D software design, ODM, and several customization options, but reports no new products in the past year, no SDK, and no OEM service for popular brands. Service-management documentation is weak: no written procedures or records are reported for assessments, corrective actions, or complaint handling. It has no in-stock capability, overseas warehouse, or overseas showroom. Financial records are indicated for 2023–2025, but their results are not provided, so financial credibility cannot be determined. No customer cases are supplied.

Supplier typeThe supplier is explicitly identified as a manufacturer/factory and limited company in Ningbo, Zhejiang, China. Its stated scope covers fasteners, metal products, machinery, vehicle parts, CNC machining, stamping, casting, die-casting, plastic, and rubber parts, indicating broad manufacturing and industrial-product coverage.

CertificationsThe supplier reports holding TS 16949 and ISO 9001 management-system certifications. It also states that each shipment will include an effective inspection report and corresponding material certificate, providing explicit evidence of documented quality-related controls.

After-Sales capabilityThe supplier reports no written procedures or records for service-capability assessment, corrective and preventive actions, or effective customer-complaint handling. It also lacks in-stock service, overseas warehouse, and overseas showroom capabilities, indicating a documented weakness in after-sales and service infrastructure.

Production capacityThe supplier reports more than 10 production lines, 6–10 quality-control staff, and a product range spanning vehicle parts, CNC machining, stamping, casting, die-casting, fasteners, plastic, and rubber parts. It is located near Ningbo and Shanghai ports and reports 21 qualified suppliers, but has no inventory capability and peak-season lead-time data is inconsistent or unclear.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, 3D software design services, and ODM services. These statements provide direct evidence of broad product and design customization capability.

Product Q&A

Q:What is the difference between DIN 982 and DIN 985?

A Prevailing Torque Nut manufactured to DIN 982 has a taller nut body than DIN 985, providing longer thread engagement. DIN 985 is the lower-profile version for more compact assemblies.

Q:Where are these locking nuts commonly used?

A vibration-resistant nut is commonly used in automotive components, industrial machinery, agricultural equipment, construction equipment, electrical assemblies, and other connections exposed to movement or vibration.

Q:Can a nylon insert nut be reused?

A Nyloc Hex Nut may be reused only when the nylon insert remains undamaged and still provides the required locking torque. For critical connections, replacing the nut after removal is recommended.

Q:Is this product suitable for high-temperature environments?

A Polyamide Insert Nut is not normally recommended for continuous high-temperature applications because heat can reduce the locking performance of the nylon ring. An all-metal lock nut may be more suitable.

Q:Can non-standard specifications be manufactured?

Yes. Custom Hex Lock Nuts can be produced with specified thread sizes, fine pitches, nut heights, insert materials, surface requirements, markings, and packaging according to drawings or samples.
