Security Screw, Countersunk, 6-Lobe/Resistorex, Hafren Fasteners

Product Details

How do I identify the correct bit for this Security Screw?

This screw uses a T20 security drive. You will need a T20 security Torx compatible bit or driver for a snug fit, helping reduce cam out during installation.

What does the 6 lobe security drive mean?

The head features a 6 lobe, Resistorx style drive. This is designed to work with the matching security driver pattern, making the screw less accessible with standard tools.

Is this screw suitable for countersunk applications?

Yes. It has a countersunk head designed to sit flush with the surface when used with the correct pilot preparation. This makes it a good choice for tidier finishes in furniture, fixings, and internal assemblies.

What size is the Security Screw 6 Lobe Csk T20?

The stated size is 4.2 mm diameter by 38 mm length. This length is commonly used where you need a secure hold without using an overly long fixing.

Is stainless steel the best option for indoor or outdoor use?

As it is made from stainless steel, it offers good resistance to corrosion for many applications. For exterior installations, always consider your environment, such as coastal exposure, to confirm suitability.

How many screws are included in the pack?

This pack contains 100 screws. Buying a multi pack is useful for projects and repairs where you want consistent fixing size and drive type.

Will I need any special tools besides the T20 security bit?

In most cases, you only need the T20 security bit and the correct driver or screwdriver tool. If you are fitting into wood or other materials, having an appropriate pilot hole tool can improve alignment and reduce splitting.

What is the product part number for ordering?

The product part number is 010.93.044. Using this when ordering helps ensure you receive the exact 4.2 x 38 mm, T20 security, 100 pack version.
