FIX expansion plug fi 12 with DIN 571 hex head screw 8.0x60 mm polypropylene /50pcs/ FIX-12/60

Professional expansion plug for solid substrates

The FIX expansion plug fi 12 with a hexagonal screw is an advanced anchoring solution designed specifically for high-density solid substrates. The two-way expansion sleeve system guarantees exceptionally high load-bearing parameters and mounting stability in concrete and solid brick.

The two-way expansion mechanism distributes forces evenly within the mounting hole, resulting in maximum connection strength. Integrated anti-rotation wings effectively block the plug from rotating during tightening, eliminating the risk of loosening the connection even under dynamic loads.

Construction and materials

The sleeve with a diameter of 12 mm and a length of 60 mm is made of high-quality polypropylene, which is characterized by resistance to aging and dimensional stability under varying thermal conditions. The material maintains its mechanical properties across a wide range of operating temperatures.

Special stabilizing lugs on the plug body facilitate precise seating in the hole before starting assembly, preventing uncontrolled movement during installation. The anti-rotation wings are strategically placed to maximize friction with the hole walls.

The dedicated screw with a diameter of 8,0 mm and a length of 60 mm features a hexagonal (HEX) head, allowing for the transfer of significant torque using standard socket tools or screwdrivers with the appropriate bit.

Professional applications

The FIX-12/60 system finds wide application in professional installation and construction works. It is ideal for mounting heavy elements such as hanging cabinets, installation brackets, and wall supports that require solid anchoring.

In the electrical installation industry, the product is used for mounting cable trays, conduit pipes, and lighting fixtures mounted directly to concrete or masonry substrates. The two-way expansion ensures connection reliability even under the variable loads typical for electrical installations.

In finishing works, the plug is effective for mounting frames, decorative profiles, and cover strips that require aesthetic and durable fastening to solid substrates.

Installation and operation

Correct installation requires drilling a hole with a diameter of 12 mm and a minimum depth of 70 mm, accounting for excess debris and the full length of the sleeve. It is crucial to thoroughly clean the hole of dust by multiple blow-outs with a hand pump or brush - the cleanliness of the hole directly affects the friction between the sleeve and the hole walls.

The plug should be placed in the hole through the mounting element until the surface of the sleeve is flush with the substrate. Then, tighten the screw with a hexagonal key or an appropriate socket until a distinct resistance is felt, signaling the full two-way expansion of the sleeve.

The product is available in a practical cardboard packaging containing 50 pieces, which facilitates logistics on larger construction sites and minimizes packaging waste when executing projects of various scales.
