Security Screw, Sentinal One Way Pozi Drive, Hafren Fasteners

Product Details

Will these work with a standard PZ2 screwdriver bit?

Yes. The Security Screw Sentinal 1W is designed for a PZ2 drive, so you can use standard Pozi or SupadrivePZ2 for the best grip and reduced risk of cam out.

What does the size 4.2 x 32 mm mean?

4.2 mm refers to the screw thread diameter, and 32 mm is the screw length from under the head to the tip. This helps you confirm you have the correct length for your boards, brackets, or fixings so the screw penetrates properly without going too deep.

Are these screws fully threaded?

Yes. These are fully threaded, which is useful when you want stronger holding through the full length of the screw. Fully threaded security screws are often chosen for secure assemblies where consistent pull through the material is important.

How many screws are included in the pack?

You get 200 screws per pack, in a convenient batch size for larger jobs, repeat installs, or workshop stock. If you regularly fit security screws, a larger pack can help reduce downtime from re ordering.

What is the thread diameter and will it match my existing fixings?

The thread diameter is 4.20 mm. If you are replacing existing screws or using previously drilled holes, match the original size to ensure a proper fit. Correct sizing helps the screw bite reliably and improves holding performance.

Which tools do I need to install the Security Screw Sentinal 1W PZ2?

You will need a PZ2 cross slot bit or screwdriver with a PZ2 drive. If you are using power tools, choose the right bit quality and keep the driver aligned to minimise slipping and protect the screw head.

What is this product part number and why does it matter?

The product part number is 010.93.063. Using the exact part number makes it easier to reorder the same screw size and drive type, especially when you are matching hardware for ongoing maintenance or completing the same project later.
