Express anchor stainless steel 20/30/172 MAX

The Upat Express Anchor MAX A4 is the champion in its class when it comes to bolt anchors. This stainless steel anchor is particularly suitable for fastening medium to heavy loads in outdoor areas or in damp environments in cracked and uncracked concrete and natural stone with a dense structure. The Express Anchor MAX A4 can be conveniently installed in pre- and push-through mounting and hammered into the blown-out drill hole with little effort. When the nut is tightened in an installation-friendly manner, the bolt pushes itself into the expansion clip, which expands against the borehole wall using proven technology, thus ensuring maximum holding security. The bolt anchor is used particularly frequently for fastening canopies, support feet and balcony railings.

• Comprehensive approval package: ETA concrete approval option 1, seismic, fire resistance and sprinkler systems
• High load capacity: Thanks to the optimal interaction of the expansion clip design and the cone area
• Flexible installation: Variable anchoring depths allow versatile use of the bolt anchors
• Fastening close to edges: The cone and expansion clip unit enables minimum edge and centre distances
• Easy to install: Shaft with optimised diameter for low impact energy
• Protected thread: Distinctive impact pin protects the thread from damage during the setting process
• Reliable follow-up check: The head embossing enables follow-up checks when installed
• Secure driving: The clip remains in position during driving, even if it hits reinforcement or encounters unfavourable drill holes.

Material

• Stainless steel (R/A4): For fastenings outdoors or in damp rooms.
• Galvanised steel (gvz): For fastenings in dry indoor areas.

Variant

• Short (K): The short version of the bolt anchor reduces the drill hole depth and the risk of hitting reinforcement, and enables quick installation while saving costs
• Large washer (GS): The large washer protects the surface of the attachment and prevents cutting into wood

Approved for:

• Concrete C20/25 to C50/60, cracked and uncracked

Also suitable for:

• Natural stone with dense structure

Function: When the nut is tightened, the bolt pushes into the expansion clip, which spreads against the borehole wall. If cracks appear in the building material, the expansion element is retightened by the cone and the load-bearing capacity of the anchor is maintained.

Installation: The Upat Expressanker MAX is installed using through-hole mounting. Drill the hole, clean the drill hole. Drive in the bolt anchor. Tighten to the specified torque – done. The bolt diameter is equal to the drill hole diameter.

Tools: Drill, drill press, blow-out pump (UPM AB), hammer, torque wrench
