• Countersunk head pulls flush into a chamfered hole for a neat, level surface.
• Supplied with a matching hex full nut, so no need to buy fixings separately.
• Machine thread for use through drilled or tapped holes, not into timber.
• Zinc plated steel (BZP silver) for a clean look and everyday corrosion resistance.
• Slotted or Pozi drive to match common screwdrivers and bits.
• Handy for light-duty bolting on brackets, fixtures and general repairs.
• Metric sizing keeps it easy to match washers and other components.

Reach for these where you fix through a hole and want a nut on the back rather than a self-tapping screw biting into wood. Typical jobs include:

• Bolting metal brackets, plates and mounting feet.
• Fitting signage, panels and trim where a flush head matters.
• Securing electrical enclosures, back boxes and cover plates.
• General light fabrication, model work and machinery repairs.
• Any assembly with pre-drilled holes that needs a tidy countersunk finish.

What is the difference between a machine screw and a wood screw?

A machine screw has a uniform metric thread and needs a nut or a tapped hole to hold it. A wood screw has a coarse, tapering thread that cuts its own grip into timber. These are machine screws, so they pair with the supplied nut and won't bite into wood on their own.

Do these come with nuts?

Yes. Each screw is supplied with a matching hex full nut, so you can bolt through a hole straight away.

What thread do they have?

A standard metric machine thread. That means you can also run them into a matching tapped hole if you prefer not to use the nut.

What is the difference between a countersunk and a pan machine screw?

A countersunk head is cone-shaped and sits flush in a chamfered hole. A pan head is rounded and sits proud on the surface. Pick countersunk when you want a level finish with nothing standing above the workpiece.

Are they suitable for outdoor use?

The zinc plating handles dry, indoor conditions well. For exposed or damp locations, a stainless or higher-spec coated fixing is a better long-term choice.
