Introduction to Tool-Less Access Fasteners
Tool-less access fasteners are essential for applications requiring quick removal and installation of cover panels, especially in high-altitude environments like telescopes. These fasteners facilitate efficient maintenance and adjustments without the need for specialized tools.
Typical Applications
In our custom instrumentation for large telescopes:
- Removable cover panels are frequently employed.
- Quick removal and installation of these panels is crucial.
- Retained fasteners enhance operational efficiency.
- Tool-less access is particularly desirable in high-altitude applications (3000 m – 4000 m).
Customer Inquiry on Pushbutton Studs
Recently, a potential customer provided a sample of a pushbutton stud receptacle, which highlights the need for effective fastening in our designs. Here’s a summary of the inquiry:
- Part Information: The supplied receptacle’s part number has been replaced with the new part number MTHRTZZ.
- Material Specifications:
- Cover thickness typically ranges from 1 mm to 3 mm.
- The proposed MTHRTZZ is expected to suit standard mounting frames.
Fastener Options Available
Suggested Fasteners:
- Stud for Cover Thickness 0.7 – 2.3 mm
- Type: Nickel Plated
- Length: MPPTL-1N
- Stud for Cover Thickness 2.3 – 3.8 mm
- Type: Nickel Plated
- Length: MPPTL-3N
Considerations for High-Altitude Applications:
- Wet Conditions: Assess the suitability of fasteners under wet conditions.
- Outgassing of Plating: Ensure selected materials do not outgas in high-altitude settings.
- Stainless Steel Option: A flush stainless steel version is available but may be more costly and requires minimum order quantities.
Purchasing Information
Currently, our preference is to work directly with customers, especially as our distributors in Australia do not regularly stock our products.
- Direct Purchase: Interested parties can inquire about purchasing directly from Turnlock.
- Local Distribution: We’ve successfully collaborated with 37 companies in Australia.
Conclusion
For the project currently in prospect, we anticipate requiring a minimum of 100 units. Please reach out if you have further questions or need assistance with your fastener needs.
