FAQs

What is the primary use for these concrete screws?

These screws are designed for securely fastening fixtures and fittings directly into concrete or masonry surfaces.

What does the ZYP coating do?

The ZYP coating provides protection against rust and corrosion, enhancing the screw's durability and lifespan, especially in outdoor or damp conditions.

Do I need to drill a hole before using these screws?

Yes, a pilot hole must be drilled into the concrete using a masonry drill bit before driving the screw for optimal grip and ease of installation.

Can these screws be used in brick or blockwork?

While primarily designed for solid concrete, they can often be used in solid brick or dense blockwork, provided a suitable pilot hole is drilled.

What are the dimensions of these screws?

The dimensions are 7.5mm in diameter and 200mm in length.

How many screws are in a box?

Each box contains 100 screws.

Can I use these for structural applications?

These screws are intended for general-purpose fixture and fitting applications. For critical structural connections, consult engineering specifications and use appropriately rated fasteners.

Troubleshooting

Screw not gripping concrete

Ensure the pilot hole is the correct size and depth. Clean dust from the pilot hole. Verify the screw is being driven into solid concrete and not a void.

Screw head not sitting flush

Confirm the pilot hole is adequately countersunk at the surface. Check that the surrounding concrete is not impeding the screw head.

Difficulty driving the screw

Use a high-quality driver bit and ensure your drill/driver has sufficient torque. Check that the pilot hole is clean and free of debris.

Screw appears to be corroding

While ZYP coated, prolonged exposure to highly aggressive chemicals or environments might affect the coating. Clean the area and monitor. Ensure proper installation away from direct contact with corrosive substances.

Pros and Cons

Pros

  • Provides a clean, flush finish due to the countersunk head.
  • Durable construction ensures longevity and reliability in concrete.
  • Corrosion-resistant coating enhances lifespan, especially in exposed areas.
  • Designed for straightforward installation in concrete.
  • Suitable for a wide range of fixture and fitting applications.

Cons

  • Primarily designed for concrete; may not be suitable for other materials.
  • Requires pre-drilling pilot holes in concrete for proper installation.
  • Specific size (7.5 x 200mm) may not fit all project requirements.

Setup, Compatibility & Care

Setup:

  1. Select Appropriate Drill Bit: Use a masonry drill bit sized for the correct pilot hole diameter, as recommended for your specific concrete hardness and screw size.
  2. Drill Pilot Hole: Drill a pilot hole into the concrete to the required depth. Ensure the hole is clean and free of dust.
  3. Insert Screw: Drive the JCP Fixings Concrete Screw into the pilot hole using an appropriate driver bit. Apply steady pressure until the screw is securely seated.

Compatibility:

These screws are specifically designed for use in solid concrete and masonry. They are not intended for use in wood, metal studs, or other building materials.

Care:

While the ZYP coating provides excellent corrosion resistance, it is advisable to inspect the screws periodically, especially in harsh environments. Keep the installation area clean to prevent abrasive materials from damaging the coating. For routine cleaning, a dry or slightly damp cloth can be used.
