Key features

Formed from precision-profiled stainless steel wire, this DIN 8140-1 Wire Thread Insert creates a durable internal thread in aluminum, magnesium, plastic, and other low-strength base materials.

The Free Running Helical Coil Insert allows smooth bolt installation with minimal additional resistance, making it suitable for assemblies that require repeated fastening and removal.

Its diamond-shaped wire section distributes load across multiple thread flanks, helping the Stainless Steel Screw Thread Insert reduce thread wear and improve pull-out resistance.

Multiple strength options are available for the High Strength Hexagon Nut, allowing it to be matched with different bolt grades and assembly loads.

Sizes, thread pitches, property classes, markings, finishes, labels, and packaging can be customized for OEM Industrial Nuts according to project requirements.

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 problems can this wire thread insert solve?

A Thread Reinforcement Insert can restore damaged threads, strengthen newly tapped holes, and extend the service life of components made from softer materials.

Q:What preparation is required before installation?

The mounting hole must be drilled and tapped with the correct STI tap. The Helical Thread Insert is then installed using a matching insertion tool, followed by tang removal when required.

Q:How should the correct insert length be selected?

The required Metric Coil Insert length depends on the base material, thread diameter, available hole depth, and design load. Common lengths are expressed as multiples of the nominal thread diameter.

Q:Is this product the same as a locking wire insert?

No. A Free Running Thread Insert provides smooth screw movement, while a locking type contains deformed coil sections that generate prevailing torque against the mating screw.

Q:Can these inserts be supplied for blind and through holes?

Yes. Custom Wire Thread Inserts can be selected for blind-hole or through-hole applications by matching the insert length, installation depth, tang-removal requirement, and available thread engagement.
