Expander Bolt Stainless A4 15x125mm/5mm 5pcs Fast 287991

Description

Fixed expander bolt in acid-resistant stainless steel (A4) is the obvious choice when you need to install heavy objects in tough environments. The acid-resistant steel quality makes this expander optimal for outdoor use, coastal areas and other demanding environments where maximum corrosion protection is required.

The upper part of the bolt is externally threaded and comes complete with nut and washer for quick and easy installation. In the lower part is an expander collar that expands mechanically when the nut is tightened, which means that the bolt is wedged with enormous force in the substrate.

To ensure safe installation, the expander is equipped with a clear installation depth guide. This helps you easily ensure the correct installation depth, regardless of whether you are installing with a standard depth or a reduced depth for thinner concrete slabs.
