Screw grommets are specialized fastening components combining threaded screws with protective grommets. They provide secure mechanical fixation while protecting mating surfaces from scratches, electrical insulation, or environmental sealing. These hybrid components are critical in electronics, automotive, and industrial equipment assembly, offering simultaneous mechanical and functional performance.
| Type | Functional Features | Application Examples |
|---|---|---|
| Metal Screw Grommets | High load capacity, EMI shielding, corrosion resistance | Military electronics enclosures |
| Plastic Screw Grommets | Lightweight, electrical insulation, chemical resistance | Consumer electronics assembly |
| Rubber Insert Grommets | Vibration damping, waterproof sealing | Marine equipment panels |
| Multi-hole Grommet Plates | Bundle cable management with threaded fixation | Industrial control cabinets |
Typical screw grommets feature: - Central threaded insert (steel/brass/aluminum) - Outer grommet body (TPE/EPDM/rubber) - Flanged head design for load distribution - Internal sealing lip structure - Anti-rotation notches on base
| Parameter | Importance |
|---|---|
| Material Hardness (Shore A 30-80) | Determines sealing effectiveness and durability |
| Thread Engagement Depth | Affects pull-out strength (critical for load-bearing) |
| Temperature Range (-40 C to +120 C) | Defines operational environment limits |
| IP Protection Rating (IP54-IP68) | Specifies dust/water ingress protection |
| Torque Resistance (0.5-5.0 Nm) | Determines installation reliability |
Primary industries include: - Automotive (door panel fastening) - Telecommunications (router chassis assembly) - Aerospace (avionics mounting) - Medical equipment (diagnostic device enclosures) - Renewable energy (solar inverter panel mounting)
| Manufacturer | Key Products |
|---|---|
| PEM Stands | SPT-250 series self-clinching grommets |
| RS Pro | Multi-seal cable entry grommets |
| Igus | Tribo-resistant polymer screw grommets |
| 3M | EMI shielding grommet with threaded bushing |
Key considerations: 1. Environmental factors (UV exposure, chemical contact) 2. Required protection class (IP rating) 3. Vibration/dynamic load conditions 4. Electrical conductivity requirements 5. Installation tooling compatibility 6. Regulatory compliance (RoHS, REACH)
Current developments include: - Nano-coated materials for self-cleaning surfaces - Integrated smart sensors in grommet structures - Biodegradable polymer composites - Automated vision-based installation systems - Multi-functional grommets combining EMI shielding with sealing
