Bondloc B270 Studlock is a permanent green coloured general-purpose adhesive for permanent threaded assemblies. B270 locks studs up to 1in, sealing against leakage and corrosion. It is chemical-resistant, resisting fuels, lubricants and most industrial liquids and gases.

It eliminates double nutting and/or welding of critical assemblies. It also permits reduced casting thickness and ultimate lightness, reduced assembly stress and eliminates cracked castings due to interference fit stresses.
