Panel Fasteners (Quarter-Turn Fasteners)
Panel Fasteners, commonly known as Quarter-Turn Fasteners, are quick-release mechanical fasteners designed for secure yet tool-free attachment of panels, enclosures, and access doors. These fasteners provide high-strength retention, vibration resistance, and rapid disassembly, making them ideal for aerospace, automotive, electronics, HVAC, and machinery enclosures.
At Rajal Industries, we manufacture precision-engineered Panel Fasteners conforming to DIN and general quick-release standards, ensuring high-performance fastening, corrosion resistance, and efficient usability across industrial applications.

- Stainless Steel A4-80 Panel Fastener: 700-800 MPa corrosion-resistant strength
Panel Fastener Design & Engineering Features
Quarter-Turn Mechanism for Quick & Secure Installation
- Requires only 90° rotation to engage or disengage, allowing fast and tool-free panel removal.
Locks firmly into place, preventing accidental loosening or vibration-induced failure.
Push-to-Lock & Spring-Loaded Options for Fast Access
- Spring-loaded variants provide self-retaining functionality, ensuring secure engagement even in high-vibration environments.
Push-to-lock designs allow fast engagement without the need for secondary locking mechanisms.
Ergonomic & Space-Saving Design for Compact Applications
- Available in low-profile, flush-mounted, and recessed head styles to optimize space efficiency.
Designed for tight enclosures, sealed compartments, and confined areas.
Corrosion & Temperature Resistance for Harsh Environments
- Available in stainless steel, zinc-plated, anodized aluminum, and engineered plastic variants.
Ensures protection against oxidation, moisture, chemicals, and extreme temperatures.
Compatible with Various Panel Types & Materials
- Metallic & Composite Panels – Used in aerospace, automotive, and industrial machinery covers.
Plastic & Fiberglass Housings – Ensures secure fastening in electrical enclosures, HVAC units, and telecom systems.
Thread Specifications & Precision Engineering
| Thread Type | Description | Application |
|---|---|---|
| Coarse Thread (UNC/Metric) | Ensures fast engagement and high load resistance | Machinery panels, HVAC systems, enclosures |
| Fine Thread (UNF/Metric Fine) | Provides higher tensile strength & precise load transfer | Aerospace, automotive interiors |
| Fully Threaded Quarter-Turn Fasteners | Allows maximum adjustability and secure fastening | Industrial electrical panels, control boxes |
| Partially Threaded Quarter-Turn Fasteners | Offers better shear strength & enhanced load distribution | Quick-release enclosures, tool-less access panels |
Thread Fitment & Compliance
- Metric threads conform to ISO 6H tolerances, ensuring tight and secure engagement.
- Imperial panel fasteners meet DIN 967 and general quick-release standards for universal compatibility.
Common Applications of Panel Fasteners (Quarter-Turn Fasteners)
- Aerospace & Defense Equipment – Used in aircraft interior panels, avionics access doors, and military-grade enclosures.
- Automotive & Transportation – Ensures secure attachment of dashboards, removable body panels, and engine covers.
- Industrial Machinery & Equipment – Provides quick-access fastening for protective panels, conveyor guards, and control panels.
