Industrial Rivets & Fasteners Manufacturers

What We Manufacture in This Category

Riveted fasteners create a load-bearing joint by deforming part of the fastener inside or against the workpiece. We produce the two main families: threaded inserts that leave a reusable internal thread in thin sheet, and rivets that clamp two or more layers together permanently. Both are cold-forged or machined from wire and bar, then finished and inspected as one controlled process.

Because we also run stamping and sheet metal lines, we understand the hole conditions these parts are installed into — burr height, hole roundness, sheet thickness and material grade — and we set the fastener geometry to match the mating panel rather than the other way round.

Our Riveted Fastener Range and Where Each Type Fits

Threaded inserts are supplied in round, hexagonal, flat head, countersunk, small countersunk, semi-hexagonal, through-hole and blind-hole forms. Rivets are supplied in open-end, closed-end, solid and semi-tubular configurations. Where a standard form does not match the panel, we produce the special geometry from drawing or sample.

Specifications We Hold and Configure

• Thread range: metric M1.0–M16 for rivet nuts and self-clinching nuts; imperial #0-80 to 5/8"-11 across UNC/UNF systems.
• Panel thickness: from 0.4 mm on miniature self-clinching parts up to 12 mm on heavy rivet nut bodies.
• Standards referenced: GB/T 17880 series, ISO 13918, IFI 146, ANSI/ASME B18.29.2, DIN 7340, and PEM-compatible S/CLS/SP/SMPS and Z series dimensions.
• Materials: low carbon steel, medium carbon steel, 40Cr/SCM435 alloy steel, SUS304 and SUS316 stainless steel, H59 brass and 6063/6061 aluminium alloy.
• Finishes: blue-white zinc, coloured zinc, black zinc, nickel, zinc-nickel, Dacromet, electrophoresis, PVD, passivated stainless, with neutral salt spray resistance from 72 to 500 hours on standard finishes.
• Strength classes: 4.8, 8.8, 10.9 and 12.9 where the application calls for a high-strength threaded insert or rivet.

Application Fit Across the Product Families

Rivet nuts and blind nuts suit enclosures and frames where the reverse face is inaccessible and a serviceable thread is needed for later assembly. Self-clinching nuts and studs suit flat sheet metal panels processed on automated press lines, where the serrated shoulder is embedded in one stroke and the panel then moves to final assembly without drilling or tapping.

Expansion rivet nuts fit thin plates, sheet metal and plastic parts where welding is impractical. Blind rivets serve brackets, panels and enclosures assembled from one side, with closed-end versions used where the joint must resist moisture or retain a sealed cavity. Solid and semi-tubular rivets are chosen for permanent, high-vibration joints such as hinges, contacts and structural pivots.

Manufacturing and Quality Control

Riveted fasteners are produced on cold heading lines covering M0.8–M16 with forming lengths up to 190 mm, dedicated nut machines from M2 to M14, and cam lathes for stepped and special-shaped bodies. Incoming wire and bar are checked by spectrometer sampling before forming, and heat treatment is controlled to surface hardness HRC38–48 with a carburized layer of 0.003–0.005 mm where specified.

Our enclosed precision testing laboratory operates to IATF16949, ISO9001 and ISO14001 system requirements and covers dimensional inspection on a Zeiss CMM and 2.5D vision system, mechanical testing for tensile, torque and hardness, salt spray and humidity cycling, and metallographic analysis of carburized layers and failure modes. On request we issue material certificates, dimensional reports, salt spray reports, mechanical test reports, RoHS declarations and PPAP documentation.

Installation, Tooling and Line Integration

Rivet nuts and expansion nuts are set with a manual or pneumatic riveting tool; self-clinching parts are installed with a press and a matching anvil. We supply the fastener geometry, recommended hole size and installation force range so the setting tool and press stroke can be matched to the joint, and we can review the mating panel drawing to confirm hole tolerance and edge distance before tooling is cut.

For automated assembly, we control thread concentricity, head flatness and knurl form so parts feed reliably through vibratory bowls and pick-and-place heads. Where a project moves from prototype to volume, we keep the same tooling definition across the Suzhou and Vietnam bases so the installed part behaves identically at both sites.

Information We Use to Configure Your Solution

• Panel material, grade and thickness at the joint, plus hole diameter and tolerance.
• Required thread size and pitch, or rivet diameter and grip range.
• Head form and whether the installed side must sit flush with the panel surface.
• Load case: tensile, shear or torque, and whether the joint is permanent or serviceable.
• Environment and corrosion target, expressed as salt spray hours or a specific finish.
• Installation method, tooling already in use, and annual or per-release volume.
• Inspection and documentation requirements, including AQL plan and report format.

With these inputs we select the body geometry, material and finish, confirm the setting parameters, and quote against the production route that fits the volume. Prototype and pilot quantities are supported before a mass-production release.

Frequently Asked Questions

Which riveted fastener should be used when only one side of the panel is accessible?

A rivet nut, blind nut or blind rivet. Rivet nuts and blind nuts leave a reusable internal thread after the body expands against the panel, while blind rivets form a permanent second head from the front side. Both are installed without welding and without access to the reverse face.

What is the difference between a rivet nut and a self-clinching nut?

A rivet nut deforms inside the hole and locks by expansion, so it tolerates a wider hole tolerance and works on closed sections. A self-clinching nut is pressed into the sheet so its knurled or serrated shoulder displaces panel material, giving a flush, high-pushout joint on flat sheet that suits automated press installation.

Can you produce non-standard rivet nuts and rivets to our drawing?

Yes. We develop special parts from drawings, samples and application data, covering non-standard thread sizes, head forms, knurl patterns, expansion structures and stepped bodies. Complex multi-step geometries can be produced by combining cold heading with CNC turning.

What documentation is issued with a riveted fastener shipment?

Depending on the project, we issue material certificates, full-dimensional inspection reports, salt spray test reports, mechanical test reports, RoHS declarations, 8D improvement reports and PPAP documentation. Inspection plans can be set to your AQL standard, and test schemes can be adapted to your internal specification.

How are riveted fasteners packed and delivered for volume programs?

Parts are cleaned, inspected and packed in bulk or in feeder-ready containers according to the assembly method. Packaging, labelling and delivery scope are agreed at order confirmation, and production can be allocated across our China and Vietnam plants for stable supply.
