Product Details

Is this screw in sleeve compatible with an M4 screw?

Yes. This sleeve has an M4 internal thread, designed to accept an M4 screw. It is intended for use with the matching thread size so you can achieve a secure, repeatable fixing.

What hole size do I need to fit this sleeve?

Use a Ø 6.2 mm hole. The sleeve is specified for installation into a 6.2 mm diameter hole, helping ensure a good fit and reliable hold in the base material.

What are the key dimensions of the sleeve?

Length 8 mm with an outer diameter of 8 mm and a core diameter of 5.5 mm. These dimensions affect how far the threaded section engages and how the sleeve sits in your workpiece.

Will it work if my application needs a slot drive during fitting?

Is the zinc plated finish suitable for general use?

It is zinc plated, which provides basic corrosion resistance for many indoor and light outdoor applications. If you are fitting in a harsh environment, consider whether your project needs additional protection.

How many sleeves are included in the pack?

You get 100 sleeves per pack, which is convenient for larger jobs, repairs, or having spares on hand. Buying in bulk can also help keep your costs consistent across multiple projects.

Where can I use a screw in sleeve like this?

It is commonly used to create a strong threaded insert in materials where you want a reusable thread for M4 screws. This can help improve assembly reliability compared with cutting threads directly into softer materials.
