Product Information

Full details

The Unifix Machine Screws (M4 x 10) are professional-grade fasteners designed for hobbyists, DIY enthusiasts, and tradespeople who require a secure, reliable connection in metal, wood, or plastic applications. Featuring a standard Pozi pan head design that adheres to DIN 7985Z specifications, these screws offer superior torque control and a flush fit. While they provide excellent versatility for common hardware assemblies, users should ensure their project materials are pre-drilled appropriately, as these machine-threaded screws are not self-tapping.

Extended Product Information

FAQs

Are these screws self-tapping?

No, these are machine screws and require a pre-drilled and tapped hole or a captive nut.

What drive type do I need?

These screws use a Pozi (PZ) drive. A Pozi screwdriver is recommended for the best fit and torque transfer.

What is the diameter and length of these screws?

These are M4 screws with a length of 10mm.

Can I use these for outdoor projects?

While durable, they are standard machine screws; check the environmental requirements of your project to see if stainless steel alternatives are needed.

Do these come with nuts?

This product listing refers to the screws themselves. Nuts are usually sold separately unless specified otherwise.

Are these compatible with metric threads?

Yes, they follow the standard M4 metric specification.

Troubleshooting

Screw head keeps slipping (cam-out)

Ensure you are using a Pozi-compatible driver, not a standard Phillips screwdriver, and apply firm, steady pressure.

Screw will not start into the hole

Verify that the hole is threaded for M4 size and check the entrance for debris or metal burrs.

Screw feels loose after tightening

Check if the mating nut or threaded hole is stripped; use a thread-locking compound if vibration is a concern.

Pros and Cons

Pros

  • High-quality Pozi drive prevents slipping
  • Standardized threading for reliable compatibility
  • Durable grey finish for a clean aesthetic
  • Easy to install with standard screwdriver tools

Cons

  • Requires a pre-tapped or threaded hole
  • Limited length of 10mm may not suit thicker mounting surfaces
  • Not intended for self-tapping into raw wood

Setup, Compatibility & Care

To install these screws, ensure you are using a correctly sized Pozi screwdriver to avoid damaging the head cross-recess. These screws require a pre-threaded hole (M4 tap) or a matching captive nut for proper installation. Avoid over-tightening with power tools to prevent stripping the threads. To maintain the integrity of the finish, store them in a cool, dry place to prevent moisture accumulation. If using these in outdoor or high-humidity environments, consider a light application of machine oil to prevent oxidation.
