⚡ At a Glance
- • Fixing Strength: Self-adhesive backing combined with locking washers secures insulation up to 60 mm thick on smooth, clean surfaces.
- • Best for: DIYers and tradespeople fitting insulation panels where fast, tidy installation is required.
- • Not ideal for: Porous, rough or contaminated surfaces where adhesive backing cannot form a reliable bond.
Pack contains 50 sticks, each 62 mm long with a 2.7 mm pin diameter. Galvanised sheet steel construction and included locking washers provide mechanical support alongside the adhesive base.
Secure adhesion even overhead, with self-adhesive backing and locking washers
Self-adhesive backing forms the initial bond on smooth, clean surfaces while locking washers add mechanical grip around the 2.7 mm pin. The combination reduces movement of insulation during and after fitting.
Firm hold during installation makes overhead work easier, users report straightforward placement and steady adhesion.
Fits common panel depths, with 62 mm length for up to 60 mm insulation
A 62 mm shaft allows the pin to pass through insulation up to 60 mm thick, giving sufficient engagement for the locking washer to clamp the panel. Pin diameter of 2.7 mm balances strength and minimal intrusion.
Suitable for a wide range of insulation panels, ensuring the panel sits flush against the surface for a neat finish.
Durable metal construction, with galvanised sheet steel
Galvanised sheet steel resists corrosion and provides rigidity to the pin and washer assembly, preserving mechanical integrity over time. Zinc coating helps reduce surface rust in typical building environments.
Longer service life in damp or exterior-adjacent areas, offering reassurance that fixings remain effective over time.
