Extended Product Information

FAQs

What is the thread size of these screws?

These screws have a 10mm (M10) diameter.

Can these be used outdoors?

Yes, their brass construction provides natural resistance to corrosion.

Are these fully threaded?

Yes, the DIN 933 standard indicates that the screw is threaded along its full length.

What tool should I use to tighten them?

A standard metric spanner or socket wrench is required for the hexagon head.

Can I use these in metal?

Yes, they are suitable for use in metal provided you have a pre-drilled and tapped hole of the correct size.

Troubleshooting

Screw feels difficult to turn during installation

Back the screw out and check for cross-threading or debris in the hole before re-inserting.

Rounding of the hexagon head edges

Ensure the wrench or socket is the correct metric size and fully seated on the head before applying torque.

Pros and Cons

Pros

  • High resistance to corrosion due to brass composition
  • Standardised DIN 933 threading ensures component compatibility
  • Hexagon head allows for high-torque tightening
  • Durable construction suitable for long-term use

Cons

  • Brass is softer than steel and can strip if overtightened
  • Not suitable for extreme high-load structural steel applications
  • Requires manual tool access for the hexagon head

Setup, Compatibility & Care

For optimal results, ensure the pilot hole or tapped hole is clean and free of debris before insertion. When driving the screw, use a properly sized wrench or socket to prevent rounding the edges of the hexagon head. While the brass finish is corrosion-resistant, it should be kept away from harsh acidic chemicals that may cause oxidation. If used in outdoor or marine environments, regular inspection for debris accumulation is recommended. When tightening, apply steady pressure to ensure the thread seats correctly into the mating material.
