Weld spatter & rework

62 % of fabricators report >8 % rework due to poor locking weld nut seating. Every rework costs $45– $120 in labor.

Inconsistent thread quality

Low-cost weld in nut inserts from unknown sources often fail Go/No-Go gauges — halting your production line.

Hidden shipping & tariffs

"Cheap" weld nut gun offers often exclude freight & duty. Total landed cost can be 40 % higher than quoted.

Lead times of 8–12 weeks

Most suppliers can't deliver welding nuts in less than 60 days. We ship 15–25 days — even for custom OEM.

Precision weld in nutserts

M4 – M12, carbon steel / stainless 304/316, with or without locking weld nut feature. Thread class 6H, ISO 9001 & RoHS certified.

Locking weld nut (nylon patch)

Integral locking element meets IFI 100/107. Reusable 5+ times, ideal for high-vibration applications (agriculture, construction).

Q1: What is the difference between a weld in nut insert and a locking weld nut?

A weld in nut insert is a threaded insert designed to be welded into a host material. A locking weld nut has a built-in nylon patch that resists vibration loosening. Both are weld in nutserts — we offer both types with full traceability.

Q2: Do you supply a nut welding gun that works with all weld nutserts?

Yes, our weld nut gun (model BFN-500) is compatible with M4 to M16 weld in nutserts and locking weld nuts. It features a dual-pistol grip and adjustable current to minimize spatter.

Q3: What are your minimum order quantities and lead times for weld in nut inserts?

MOQ: 5,000 pcs for standard sizes (M4–M12). Lead time: 15–25 days for standard, 25–35 days for custom OEM. We also offer sample orders (50–100 pcs) for qualification.

Q4: How do you ensure quality for locking weld nuts and welding nuts?

Every batch is tested for thread accuracy (6H), tensile strength, and locking torque. We provide ISO 9001, CE, RoHS, and FCC certs. Third-party inspection (SGS, TÜV) is also available.

Q5: Can you help with OEM/ODM custom designs for weld nutserts?

Absolutely. Our engineering team has 10+ years of experience in weld in nut inserts customisation — flange shape, thread pitch, locking patch, and packaging. Send us your drawing or sample.

Q6: What shipping methods do you use for Europe and the USA?

We ship via FOB Tianjin, CIF Hamburg/Rotterdam, or DDP to major US ports. We handle all documentation, including certificate of origin, bill of lading, and tariff classification.

Q7: Do you offer free samples for weld nut guns or locking weld nuts?

Yes, we provide free samples for weld in nutserts and locking weld nuts (up to 20 pcs). You only pay shipping. For nut welding guns, we offer a 30-day money-back guarantee.

Marcus Jensen

Purchasing Manager, AgriParts GmbH (Germany)

"We switched to Boen's weld in nutserts and saved 37 % on total landed cost. The locking weld nut performs flawlessly on our tractor assembly line. Delivery was 18 days — half the usual."

Sofia Chen

Technical Director, EnerCon Structures (USA)

"The nut welding gun from Boen reduced our spatter rate by 34 %. Their technical team helped us select the right weld nut gun for our HVAC ductwork. Highly recommended."

Ahmed Al-Rashid

Supply Chain Manager, Gulf Automotive (UAE)

"We tested locking weld nuts from three suppliers. Boen's had the best thread consistency and the nylon patch held after 5 cycles. Now we order 50k/month."
