What are the Available Lengths for Excalibur Screwbolts?
Excalibur screwbolts, a type of high-performance masonry anchor, are not available in a single, universal length. Instead, they come in a variety of lengths designed to accommodate different applications and material thicknesses. These lengths range broadly from 30mm to 300mm, depending on the bolt's specific diameter.
Understanding Excalibur Screwbolt Lengths by Diameter
Excalibur screwbolts are known for their strong, reliable fixing capabilities, eliminating the need for additional plugs or chemical resins. Their robust design allows for high pull-out loads, making them suitable for a wide array of construction and structural fastening tasks. The ideal length for a particular application will depend on several factors, including the thickness of the material being fastened and the required depth of embedment for optimal performance.
To provide a precise overview of their lengths, it is essential to consider the bolt's nominal diameter. The available lengths vary significantly across different diameters, offering flexibility for diverse project requirements.
The table below details the available lengths for different Excalibur bolt diameters, along with their recommended clearance hole sizes:
| Bolt Diameter (mm) | Bolt Ø Clearance Hole (mm) | Available Bolt Lengths (mm) |
|---|---|---|
| 6 | 7.5 | 30, 50, 75, 100 |
| 16 | 19 | 100, 120, 150, 200 |
| 20 | 23 | 100, 150, 200, 300 |
| 24 | 30 | 150, 200, 300 |
- Bolt Diameter: This refers to the nominal diameter of the Excalibur screwbolt itself. This measurement typically dictates the bolt's strength and suitability for different load-bearing applications.
- Bolt Ø Clearance Hole: This indicates the recommended diameter for the pilot hole that needs to be drilled into the material. This hole allows the bolt to pass through smoothly before its threads engage with the base material for a secure fix.
- Available Bolt Lengths: These are the standard lengths in millimeters in which the bolts are manufactured and supplied for each respective diameter.
For instance, a 6mm diameter Excalibur screwbolt is offered in lengths of 30mm, 50mm, 75mm, and 100mm, typically used for lighter-duty applications or thinner materials. In contrast, a larger 24mm diameter Excalibur screwbolt is available in 150mm, 200mm, and 300mm lengths, catering to more heavy-duty fastening or deeper embedment requirements in substantial structures.
Choosing the correct length is crucial for ensuring the integrity, safety, and longevity of the fastening. Always consult product specifications and application guidelines to determine the appropriate bolt length for your specific project.
