FAQs

What standard does this hex nut conform to?

The Timco Hex Nut M20 is manufactured to the DIN 934 standard, ensuring dimensional accuracy and consistent quality.

What does 'M20' refer to?

'M20' refers to the metric thread size, indicating a nominal diameter of 20mm. The standard pitch for this nut is 2.5mm.

What type of environment is this nut best suited for?

This nut is best suited for clean, dry, low-humidity environments with a Corrosion Rating of 1. It is not recommended for outdoor or high-moisture applications.

What is the purpose of the zinc plating?

The trivalent chromium zinc plating provides enhanced corrosion resistance, protecting the steel nut from rust and degradation in suitable indoor environments.

What size wrench is needed for this nut?

A 30mm socket wrench or spanner is required to fit and tighten this M20 hex nut.

How many nuts are included in a pack?

Each pack contains 2 x M20 Hex Nuts.

Troubleshooting

Nut is difficult to thread onto the bolt.

Check that both the nut and bolt threads are clean and undamaged. Ensure you are using an M20 bolt with a 2.5mm pitch. Avoid cross-threading by starting the nut gently by hand.

Corrosion appears on the nut surface.

This nut is designed for clean, dry, low-humidity environments. If used in damp or humid conditions, corrosion is likely. Relocate the assembly to a suitable environment or consider a nut with higher corrosion resistance for such conditions.

Nut feels loose after tightening.

Ensure the mating bolt is adequately tightened and secured. Verify that the correct size wrench (30mm) was used for tightening to prevent stripping or insufficient torque.

Pros and Cons

  • Comes in a practical pack of two for small to medium projects.

Cons

  • Primarily suited for internal, clean, dry, low-humidity environments.

Setup, Compatibility & Care

Setup:

  1. Ensure the mating bolt or threaded rod has the correct M20 standard metric thread with a 2.5mm pitch.
  2. Thread the nut onto the bolt by hand, ensuring smooth engagement without cross-threading.
  3. Tighten the nut using an appropriate 30mm socket wrench or spanner to the required torque.
