· Product Overview
Introducing the YITECH Precision Keyhole Mounting Bracket — a high-strength, anodized aluminum L-bracket engineered for tool-free, vibration-resistant mounting in electronics, robotics, and industrial systems.
This bracket delivers:
- Dual keyhole slots (standard: 6 mm × 12 mm) for quick, adjustable, and secure fastening — no tools required
- Solid 6061-T6 aluminum billet construction — zero warpage, ±0.02 mm dimensional control
- Hard-anodized black finish (Type III, 25 μm) — wear-resistant, corrosion-proof, and ESD-safe
- 90° precision bend with tight corner radius (R1.0 mm) — ensures rigidity and stress distribution
- Weight-optimized design: Only 48 g (standard size), yet supports >300 N axial load
Unlike stamped steel brackets (prone to flex and rust) or plastic versions (low strength), this part combines mechanical robustness, long-term durability, and field-serviceability — making it ideal for deployable, maintenance-friendly hardware.
Perfect for engineers building modular, scalable, and serviceable systems where installation speed = uptime.

| Compliance | ISO 9001, RoHS, REACH, FDA-compliant (for medical-grade variants) |
· Application Scenarios
This bracket excels in real-world, serviceable hardware deployments:
- Electronics & IoT Enclosures
→ Mounting PCBs, power supplies, or sensors to chassis/rails
→ Keyholes allow field recalibration without tools
→ Anodized surface prevents galvanic corrosion with steel screws - Robotics & Drones
→ Payload mounting for cameras, LiDAR, or communication modules
→ Lightweight yet rigid — minimizes inertia in moving arms
→ Adjustable slots compensate for minor assembly tolerances - Industrial Control Panels
→ Securing HMIs, PLCs, or terminal blocks to DIN rails or cabinets
→ Vibration-resistant design prevents loosening in harsh environments - Medical Devices
→ Mounting diagnostic sensors or display units on mobile carts
→ Non-magnetic, biocompatible (6061-T6), and easy to sterilize - Optics & Test Equipment
→ Adapter for lens tubes, filter holders, or alignment stages
→ Flat mounting surfaces ensure repeatable positioning
💡 Why engineers choose this bracket:
- Keyhole = tool-free + adjustable — saves 60% installation time
- Hard-anodized = durable (25 μm coating resists scratches & abrasion)
- Solid billet = no weak points — unlike stamped or cast alternatives
- Customizable in days — not weeks
