Frequently asked questions about the CONCRETE SCREW 7,5x65 INDU-PROG TX30/ZN/C1/ 8tk
What is the CONCRETE SCREW 7,5x65 INDU-PROG TX30/ZN/C1/ 8tk and what is it used for?
CONCRETE SCREW 7,5x65 INDU-PROG TX30/ZN/C1/ 8tk is a hardened steel screw with a bright zinc finish designed for direct fixing into pre-drilled holes in concrete, brick and hollow blocks without plugs. It is used to secure profiles, brackets and fittings and is rated for both static and pulsating loads.
Which materials can this concrete screw be used in?
The screw is suitable for concrete, solid and hollow brick, and hollow blocks. For other substrates (e.g. aerated concrete), perform on-site testing to verify practical load capacity.
What are the dimensions of the 7,5x65 screw and how deep should I drill?
7,5x65 indicates a 7.5 mm diameter and 65 mm overall length. Drill a pre-hole to approximately the same or slightly greater depth (about 65 mm) to achieve the required anchorage depth.
Do I need a plug/dowel to install this concrete screw?
No, the hardened INDU-PROG concrete screw is driven directly into a pre-drilled hole without a plug. A dowel is not required when fixing into solid concrete or solid brick.
What head does the screw have and which bit to use (TX30)?
The screw has a Torx TX30 head; use a TX30 Torx bit and a drill/driver with adjustable speed and torque for clean installation.
What is the surface finish and corrosion protection of this screw?
The screw is made from hardened steel with a bright zinc (ZN) finish, providing basic corrosion protection. For highly aggressive outdoor environments, choose specialised corrosion-resistant fasteners.
Is this screw suitable for pulsating loads and has it been tested?
Yes, the product description states the concrete screw has been tested and approved for pulsating loads, making it suitable for fixings subject to variable dynamic loading.
How does the INDU-PROG screw differ from a standard concrete screw?
INDU-PROG is a hardened, fully-threaded screw with hi-low thread for easier installation and improved holding power; it is designed for direct installation into pre-drilled holes without plugs and is tested for pulsating loads.
Is the 8-piece pack enough to fix a 50x30 profile to concrete?
The pack contains 8 screws; the number required depends on load and fixing spacing (commonly 300–600 mm). Calculate required fixings on-site based on the weight and expected loads.
Can this screw be used outdoors under a canopy or in wet rooms?
The bright zinc coating offers basic protection and is suitable for non-aggressive outdoor locations under a canopy or in dry to moderately humid rooms. For permanent outdoor exposure or very wet environments, choose corrosion-resistant alternatives.
