Key Features
- 开放式 (通孔) 设计: 允许紧固件完全穿过, enabling flexible assembly and adjustable mounting depth.
- Unrestricted Screw Length: No depth limitation — screws can extend beyond the insert as needed.
- Versatile Installation: Suitable for heat staking, ultrasonic insertion, cold pressing, and insert molding.
- Premium Materials: Available in brass (C3604) for general use or stainless steel (SUS303/304) for high-strength, corrosion-resistant applications.
- Knurled Outer Surface: Provides strong mechanical grip in plastic, preventing rotation and pull-out.
- Lightweight & Compact: Ideal for space-constrained designs where every millimeter counts.
