Anchor PFG LB

The PFG LB anchor is a fastener used for fixing into concrete, brick, and masonry bases. The anchor features an increased wedging surface, making it suitable for installation in low-strength slabs or poor-quality materials (for example, cracked concrete). The end bolt allows heavy external structures to be attached to the anchor. The PFG LB fastener consists of a threaded sleeve, an expansion washer, and expanding external petals. A standard bolt is screwed into the threaded sleeve: it is used for installing and expanding the anchor in the material, and can also serve as a fastening element for suspending external structures from the anchor. The anchor is manufactured from high-quality low-carbon steel. The steel fastener is protected against corrosion by electrogalvanizing. PFG LB-type anchors are recommended for indoor installation. Outdoors, this fastener can only be used for temporary structures.

Installation features

Installing the anchor requires following certain instructions:

• first, a hole of the recommended diameter is drilled in the material (for example, for an anchor with M6 thread and a sleeve outer diameter of 10 mm, the drill and hole diameter must also be 10 mm);
• then the hole is thoroughly cleaned of debris and drilling residue;
• the anchor is driven into the hole with a slight interference fit;
• the anchor bolt is rotated to wedge and securely fix it in the material;
• then the standard bolt can be used to attach external structures to the anchor (or the bolt can be replaced with a threaded stud, hook, or other similar fastener).

PFG LB anchors allow for a controlled tightening torque, which is convenient for remote installation or pre-installation of the fastener. The four-way expansion of the petal sleeve ensures a secure fixation even in old, cracked, or hollow wall panels.

When selecting an anchor, consider the load on the fastener from the external suspended equipment (its weight is divided by the number of attachment points to calculate the load on each individual anchor), as well as the type of base material. Reference tables allow you to select the anchor diameter and length, as well as determine the diameter and depth of the hole to be prepared for anchor installation.
