Type 302 Slotted Self-Tapping Insert

Type 308 Self-Tapping Insert

Tang-Free Thread Insert

Galvanic Corrosion Protection

High-strength aluminum alloy bolts and anti-galvanic corrosion coatings are used to minimize corrosion caused by galvanic corrosion when connecting bolts to magnesium alloy die castings.

Anti-Loosening & Sealing Bolts

Bolts achieve anti-loosening through 3-piece washers and pre-coated thread locking adhesives (chemical/physical). Sealing can also be realized by pre-coating under the head/threads or adding sealing washers to meet the strict waterproof and dustproof requirements of NEVs.

Industry Challenges

Project Cycle Cost Impact Model

In today's rapidly developing society, the core challenge for enterprise R&D is: the early decision-making window is extremely short but locks in most costs; while huge investment in later stage brings extremely high correction costs, resulting in a serious mismatch between risks and benefits.

15-85 Rule

Over-focus on explicit procurement costs while ignoring 85% of implicit costs leads to lack of systematic coordination in design, supply chain and after-sales, significantly driving up total life cycle costs.
