1. Customer Cases for 3C Electronics & Smart Wearables

We serve manufacturers of Bluetooth earphone charging cases, laptops, tablets, smart watches, routers and surveillance cameras, supplying mass I-shaped brass nuts from M1.4 to M6. Two installation methods (mold embedding & hot melt pressing) effectively solve sliding thread and nut rotation problems of plastic housings. Customers recognize our stable dimensional tolerance, strong pull-out & anti-rotation performance, stable mass delivery and defective rate below 0.3%.

Typical partners: leading digital accessory factories, smart wearable brands and security camera manufacturers, purchasing hundreds of thousands of brass inserts monthly.

2. Supporting Cases for Smart Home & Small Home Appliances

Cooperate with manufacturers of smart locks, sweepers, beauty devices, humidifiers and hair dryers, supplying both through-hole & blind-hole I-shaped brass nuts. Optimized knurling and middle groove structure resist vibration during long-term household use. Brass material offers great corrosion resistance for humid indoor environments.

3. Supporting Cases for New Energy & PV Industry

Supply stainless steel PV screws, high-strength bolts and plastic embedded brass nuts for distributed photovoltaic systems, energy storage modules and new energy vehicle electronic control housings. Our products pass long-term salt spray tests with excellent outdoor weather resistance, suitable for long-term PV station operation. We support bulk project supply and urgent spot delivery.

4. Customer Cases for Medical Devices & Precision Instruments

Supply micro precision brass nuts and small machine screws for sphygmomanometers, physiotherapy devices and testing equipment.
