Screw & anchor kit Fischer 84335 10 pcs 80 mm Nylon 8 mm

The Fischer Hammerfix N-S with countersunk head is a pre-assembled fastening set consisting of a high-quality nylon anchor and a zinc-plated nail screw. Designed for through-type installation, the anchor is pushed through the fixture and into the substrate; when the nail screw is driven in, the sleeve expands and secures the anchor in the building material. This kit is suitable for internal timber construction and general fastening tasks in solid substrates.

Advantages

The pre-fitted nylon plug and nail screw allow fast, time-saving installation without separate assembly of components. The nylon sleeve expands reliably when the nail screw is driven, creating secure anchoring in a variety of building materials. The zinc-plated nail screw provides corrosion resistance suitable for internal applications, and the countersunk head ensures a flush finish when fixing timber or other components.

Suitable for

• Fastening timber constructions and wooden profiles to masonry
• Mounting fixtures in autoclaved aerated concrete (AAC)
• Anchoring into brick or solid concrete for internal applications

When it may not be suitable

This Hammerfix N-S set is intended for internal use; it is not designed for prolonged exposure to outdoor weather or highly corrosive environments. It is also not suitable for heavy structural loads where engineered mechanical anchors or through-bolts specified by a structural engineer are required.

Key specifications

• Anchor material: nylon
• Nail screw material: zinc-plated steel
• Anchor diameter: 8 mm
• Total anchor length: 80 mm
• Drill hole diameter: 8 mm
• Package quantity: 10 pieces

How to use

Drill a hole of the specified diameter and depth into the substrate, clean out dust, insert the pre-assembled Hammerfix through the fixture and push the anchor into the hole until the countersunk head sits flush with the component. Drive the nail screw fully into the nylon sleeve using a hammer or appropriate tool; the sleeve will expand and lock the anchor in place. Check that the fixture is held securely and that the head is flush with the surface.

What to consider before purchase

• Verify that the 8 mm drill hole and 80 mm anchor length suit the substrate thickness and the component being fixed
• Confirm internal use and that zinc-plated corrosion resistance matches the application environment
• For heavy or safety-critical loads, consult structural guidance and consider stronger mechanical anchors if required

Usage recommendations

Use the kit for medium-duty internal timber fixings into AAC, brick, and concrete. Ensure proper hole cleaning before insertion and drive the nail fully so the nylon sleeve expands correctly. For exterior or high-humidity environments, choose anchors with higher corrosion protection.
