Brass Knurling Insert
A heavy-duty brass insert characterized by aggressive full-body diamond knurling covering the entire outer diameter. The deep knurl pattern maximizes frictional grip and rotational torque resistance when embedded in plastic. Manufactured from CDA 360/361 brass with tight dimensional tolerances (±0.05mm). The heavy knurling makes this insert ideal for applications with significant rotational loads — furniture fittings, appliance knobs and handles, industrial control panels, and automotive trim components requiring repeated assembly/disassembly cycles.
Key Highlights
Features & Benefits
Multi-Process Compatible
Compatible with injection mould-in, heat staking, ultrasonic insertion, and press-fit installation methods.
Multiple Knurl Options
Available in diamond, straight, cross, helical, and multi-ring knurl patterns optimized for specific host materials.
Tight Tolerances
Manufactured with dimensional tolerances of ±0.05mm or tighter. Thread pitch accuracy conforms to DIN 7965 / ISO 8140 standards.
Reusable Assembly
Brass inserts enable repeated assembly and disassembly of threaded fasteners in plastic housings without thread degradation.

Material & Quality Assurance
Moulding inserts are manufactured from CDA 360 and CDA 361 free-cutting brass, selected for their exceptional machinability. The alloy composition provides good corrosion resistance and adequate tensile strength for fastener applications.
Usage & Installation Guide
The installation method depends on the host material properties and production volume. Mould-in installation provides the strongest bond; heat staking is preferred for post-moulding installation; ultrasonic insertion creates rapid and clean installations.
