Expander Bolt Stainless Steel A4 8x85mm/20mm 10pcs Fast 287959

Description

High-quality and acid-resistant expander bolt for safe mounting of heavy objects in cracked and uncracked concrete.

Fixed expander bolt in stainless, acid-resistant steel (A4) is the obvious choice for heavy mounting outdoors, in marine environments or where the requirements for corrosion resistance are extremely high (corrosion class C5).

The expander bolt is externally threaded in the upper part and is delivered complete with pre-mounted washer and nut for a fast and smooth workflow. The lower part is equipped with an expansion collar that expands and wedges into the substrate when the nut is tightened, which provides an extremely strong and permanent anchorage.

Clear installation depth instructions directly on the expander allow you to easily ensure the correct installation depth – regardless of whether you are installing with standard depth or reduced depth for thinner concrete structures.

Primary areas of application:

• Installation of steel structures, beams and brackets in concrete.
• Outdoor structures such as balconies, railings and canopies.
• Industrial and marine environments with high humidity or salt content.
