zhjiali Hardware Upgrades High-Strength Anti-Loose Fastener Solutions for New Energy Vehicles

The booming new energy vehicle industry raises strict standards for fasteners used in battery packs, chassis and electronic control units, including anti-loose performance, vibration resistance, corrosion resistance and tensile strength. Founded in 2008, Zhuhai Jiali Hardware (zhjiali) has 18 years of manufacturing experience in fasteners. We upgraded product processes to solve core pain points of auto manufacturers, delivering full fastening solutions for passenger cars, commercial vehicles and energy storage systems, and stably supplying many leading domestic vehicle brands.

1. Premium Materials & Surface Treatment for Harsh Vehicle Conditions

Vehicles face long-term vibration, drastic temperature changes and humid corrosive atmosphere. Our new energy fasteners adopt SUS304/316 stainless steel and 10.9/12.9 high-strength alloy steel, matched with zinc-aluminum coating, dacromet and thread locking adhesive. All products pass salt spray, thermal cycling and one million vibration fatigue tests to avoid loosening, rust or fracture during driving. We also supply integrated bolts with sealing washers for battery pack waterproofing to prevent short circuit risks.

2. Complete Product Range: Stock Standard Parts & Custom Non-Standard Fasteners

Our full product line covers battery pack hex bolts, flange lock nuts, tiny electronic screws, high-strength chassis studs, rivet studs and shock-absorbing washers with abundant stock for fast sample delivery. For new vehicle integrated casting frames, we develop special stepped screws and lightweight titanium alloy fasteners according to 3D drawings or samples, greatly shortening R&D matching cycles for automakers.

3. Automatic Production & Standard Inspection for Stable Mass Delivery

zhjiali introduced CNC automatic forming, thread rolling and surface treatment lines to control unified tolerance of thread, hardness and torque. Our independent lab provides full inspection reports of dimension, tensile force and anti-loose performance for every batch. We build exclusive supply channels for vehicle projects, supporting JIT digital zero-inventory cooperation to cut customers’ warehousing costs and stabilize lead time for bulk orders.

4. Multi-Industry Supporting & Diversified Precision Fastener Market Layout

Besides new energy vehicles, zhjiali also serves medical precision equipment, automation machinery, lightweight bicycles, PV brackets and ship machinery. With our own brand Fastking standard stock and mature customization capacity, we support domestic industrial procurement and European & American export business, supplying GB/DIN/ANSI standard fasteners for one-stop purchasing. In the future, we will keep investing in new materials and anti-loose technology to become a benchmark manufacturer of high-end domestic precision fasteners.
