Threaded Stud for Chemical Anchor
FLOK supplies threaded studs for chemical anchors, made of zinc-coated carbon steel or A2/A4 stainless steel, for fixing into hollow and porous materials.
A threaded stud for chemical anchor is a threaded fastening element for securely fixing structures to hollow and porous construction materials. It is installed into a chemical bonding compound; once the compound has cured, a strong fixation in the material is achieved.
The stud has a hexagonal tip and may be fitted with conical elements for tighter fixation and resistance to pull-out. A nut is fitted on the threaded end to fasten structures.
Manufacturing features
The following materials are used for studs applied together with chemical anchors:
- Carbon steel with zinc coating to resist corrosion. The zinc coating increases resistance to moisture and chemical exposure, giving the fastener a long service life.
- Stainless steel grades A2 and A4. These materials are not subject to corrosion and are resistant to prolonged chemical exposure.
The stud is a metal rod with metric thread on one side. A nut with a washer is fitted onto it, allowing parts to be fastened. The other end may be fitted with conical elements: these resist the stud being pushed out of the wall under high external load.
Stud installation sequence
The stud is used together with a cartridge-type or injection-type chemical anchor and can be installed into hollow and solid materials. Installation is carried out in several stages:
- Preparing a hole of the required depth and diameter.
- Cleaning the hole of concrete dust using special tools.
- Filling the hole with the bonding compound: synthetic resin with hardener and a quartz sand filler.
- Inserting the stud into the filled hole and allowing time for final curing; the duration depends on the specific chemical composition.
- Installing the structure to be fastened and tightening the nut with the washer.
When installed correctly, this provides a high-strength connection resistant to heavy loads. The chemical anchor bonds firmly with the base material and cannot be removed without damaging the wall. It can be installed close to an edge, or several studs can be installed next to one another. Unlike expansion anchors, chemical anchors do not cause chipping or cracking in hollow materials.
