Combination Anchor Multi-Monti I

The Multi-Monti I combination anchor is designed for installation in concrete, brick or stone bases — with the possibility of subsequently fastening external structures to it. Multi-Monti I anchors are made of carbon steel. Additional corrosion protection is achieved by electrogalvanizing the steel surface of the anchor. This gives the fastener resistance to moisture, but its scope of application is indoor installation (outdoor use requires stainless fasteners). When installing anchors, it is important to follow the manufacturer’s recommendations to ensure reliability and the required load capacity of the fastener.

The Multi-Monti I anchor is called “combination” due to its external and internal threads:

• The external thread is cut on the anchor’s own shank and is designed for secure fixation of the fastener in the base material. The thread has sharp crests (similar to a self-tapping screw thread) and a relatively large pitch between turns.
• The internal thread is made in the sleeve at the working end of the anchor. It is used when installing the fastener (by turning a bolt or threaded rod screwed into the sleeve), as well as for subsequently fastening external structures to the anchor. Hooks, studs or similar fasteners can be screwed into the sleeve.

Installation features

• The diameter of the Multi-Monti I combination anchor is 6 mm.
• The drilled hole for the fastener must be the same diameter. Before installing the anchor, it is important to thoroughly remove dust and drilling debris from the hole.
• The minimum anchor embedment depth is at least 55 mm.
• The size of the anchor’s external hex head is 13 mm. The internal thread of the sleeve, depending on the version, is M8 or M10.
• Provided the requirements for hole diameter and anchor depth are met, the fastener’s load capacity depends only on the base material type. The recommended load for good-quality C20 or C25 concrete (without cracks) is 5.3 kN. If the base has cracks, the anchor’s load capacity is significantly reduced (no more than 0.8 kN is recommended).
