Concrete screw BTS E 6x155 with external thread M8. Quantity per package: 50 pieces. 9ZG6155M8BTSE

Concrete Screw – Universal Solution for Installations in Ceilings and Walls

With a length of 155 mm and an external thread M8, this screw excels where standard anchors fail – for example, when mounting rails, brackets, or profiles in cracked concrete and insulated plasterboard ceilings. The use of two anchoring depths allows selection of the optimal embedment level, minimizing the risk of damaging reinforcement bars.

• Approved for multiple uses – meets the requirements of ETA and CNBOP approvals, ensuring compliance with building regulations.
• Zinc-aluminum coating provides high corrosion resistance, even in humid or slightly acidic environments.
• M8 connector enables quick connection to mechanical components without additional adapters.

Key Benefits

• Fast two-step installation – first drill a hole of the appropriate diameter, then screw in the screw without the need for additional plugs.
• Two available anchoring depths increase versatility: shallow embedment reduces the risk of collision with reinforcement, while deeper embedment ensures maximum strength under higher loads.
• Various head shapes (e.g., hexagonal with washer) allow the use of both socket wrenches and screwdrivers with TX or HEX sockets, speeding up the installer's work.
• Corrosion resistance thanks to the zinc-aluminum coating extends the service life of the connection even in demanding operating conditions (e.g., HVAC or electrical installations).

Installation – Practical Guide

1. Hole preparation – use a special drill bit with the diameter recommended by the manufacturer; after drilling, clean the hole of dust and concrete debris.
2. Screwing in – using a socket wrench or a screwdriver with a TX/HEX socket, insert the screw until the selected anchoring depth (shallow or deep) is reached.
3. Stability check – after mounting the component (rail, bracket), verify the absence of play; make any necessary adjustments by gently tightening or changing the embedment depth.

Thanks to the simple "drill-and-screw" procedure, installation work is shortened by even several dozen percent, while maintaining full compliance with safety standards.
