FAQs

1. What are 2.1mm shank polymer headed pins used for?

2.1mm shank polymer headed pins are commonly used for fixing lightweight roofing membranes, breather membranes, insulation boards and similar sheet materials to timber. They’re ideal where a secure fixing is required without damaging the material.

2. What is the benefit of a polymer head?

The polymer head provides a larger bearing surface than a standard pin, helping to distribute pressure evenly across the material. This reduces the likelihood of tearing or pull-through while improving the overall security of the fixing.

3. Are 2.1mm polymer headed pins suitable for outdoor use?

Yes, many polymer headed pins are designed for external applications, making them suitable for roofing and other exposed building projects. Always refer to the product specification to confirm suitability for your intended environment.

4. How do I choose the correct length of polymer headed pin?

The ideal pin length depends on the thickness of the material being fixed and the depth required. It is important to choose the correct length to help ensure a strong, long-lasting fixing.

5. What’s the difference between polymer headed pins and polymer headed nails?

Polymer headed pins typically have a slimmer shank, making them well suited to fixing lighter materials while minimising damage during installation. Polymer-headed nails generally have a thicker shank and are better suited to applications where greater holding strength is required.
