Questions we get asked about this item
How is a long screw kept straight through insulation?
Shank stiffness and point geometry do the work. Tell us the total grip and the steel thickness at the far end and we will confirm the point and diameter.
Is the whole length threaded?
Partial thread is normal on long fixings so the plain shank pulls the layers together. Say which you need on the enquiry.
