Ancorante rapida con rondelle grande 8/10/75 MAX GS

The Upat Expressanker MAX is the master in its class when it comes to bolt anchors. This steel anchor, in a galvanised version, is particularly suitable for fastening medium to heavy loads indoors in cracked and uncracked concrete and natural stone with a dense structure. The larger pre-assembled washer allows more pressure-sensitive components to be fastened more gently and easier alignment in slotted holes. The Express anchor MAX can be conveniently placed in pre- and push-through installations and hammered into the blown-out drill hole with little effort. When the nut is tightened in an installation-friendly manner, the bolt slides 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 cable support systems and stair 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
