Vibration Loosening

Over 62% of field failures in heavy equipment are traced back to fastener loosening under cyclic vibration. Standard nutserts can’t self-lock.

Misalignment Rejects

Assembly lines report up to 15% rejection due to hole misalignment. A non-floating rivet nut offers zero tolerance for error.

Total Cost Overruns

Each rework cycle costs $18–$47 per joint (labor + downtime). For a 10,000-unit order, that’s $180k–$470k in hidden waste.

Supplier Inconsistency

Importers tell us 1 in 3 shipments from low-cost suppliers fail hardness or thread gauge checks. Quality risk becomes a supply chain crisis.

Floating Compensation

The floating rivet nut design delivers ±0.5 mm radial float, absorbing hole misalignment without compromising clamp load. Ideal for multi-layer panels and curved surfaces.

Expanding Sleeve Lock

Our expanding nutsert uses a hardened sleeve that expands radially against the parent material, creating a vibration-proof, high pull-out resistance joint (up to 2,800 N for M10).

Heavy Duty Material Grades

Choose from carbon steel (8.8/10.9), 304/316 stainless steel, or zinc-nickel alloy. All heavy duty rivet nut variants pass 480h salt spray (Zn-Ni) and –40°C to 150°C thermal cycling.

Factory-Direct Logistics

We ship 1,000+ tons/year of fasteners globally. 15–25 days lead time for standard nutserts, with OEM/ODM packaging (bulk, blister, or private label).

"We switched to Boen's heavy duty nutsert for our harvester line. Rework dropped 37% and the floating compensation saved us from scrapping 2,400 misaligned panels. Best supplier switch we've made."

Sarah Chen
Supply Chain Director, Apex EV (USA)

"The expanding rivet nut from Boen passed our 200k-cycle vibration test on the first try. Their Zn-Ni coating outperformed the Italian supplier we used before. Lead time: 18 days."

"We use heavy duty rivnut for solar tracker frames. The ±0.5 mm float eliminated shimming entirely. Installed 12,000 units with zero field failures. Boen delivers on spec."

A standard rivet nut relies on thread deformation. Our expanding nutsert uses a hardened sleeve that expands radially, creating a high-strength, vibration-proof joint. The floating rivet nut version adds ±0.5 mm radial compensation for misaligned holes.

We offer carbon steel (grade 8.8/10.9), 304 stainless steel, 316 stainless steel, and zinc-nickel alloy. For corrosive environments, Zn-Ni coated heavy duty nutsert passes 480h salt spray.

Standard MOQ is 5,000 pcs per size/material. For OEM/ODM orders (custom head marking, packaging, or thread), MOQ is 10,000 pcs. Sample orders (50–200 pcs) are available for qualification.

The ±0.5 mm radial float allows the nut to self-align with the bolt, reducing rejection rates from 15% to under 1%. This eliminates the need for shimming and rework, saving ~$0.12 per joint in labor.

We ship FOB Tianjin, CIF, or DDP to any major port. For urgent orders, express DHL/FedEx (3–5 days) is available. Typical sea freight to US/Europe takes 18–28 days. We provide full tracking and customs documentation.

Yes. We can customize head marking, flange diameter, thread length, and packaging (blister, bulk, private label). Our in-house tooling team can develop custom sizes within 7–10 days.

Our products comply with ISO 9001:2015, CE, RoHS, REACH, and FCC. We also provide test reports for pull-out, torque, and salt spray per batch. UL certification is available for select series.
