M3.5 x 50mm Flat-Head Countersunk Electrical Socket Screw - Black Nickel/Gunmetal

These M3.5 x 50mm screws are specifically designed for Screw less and Flat Plate style electrical sockets and switches, ensuring a flush and aesthetic finish.

The 50mm length is ideal for many standard installations with Screw less or Flat Plate designs. However, always measure the depth of your electrical box and socket/switch to ensure compatibility and a flush fit. If the box is shallower, a shorter screw may be required.

Clean the finish with a soft, dry cloth. For tougher marks, use a slightly damp cloth. Avoid abrasive cleaners or scouring pads, as they can damage the surface.

While the M3.5 thread might fit some standard boxes, these screws are optimized for the specific design of Screw less and Flat Plate sockets where a countersunk, flush head is essential for aesthetics. Using them with standard sockets may not achieve the desired visual result.

Countersunk means the screw head is designed to sit flush or below the surface of the material it's fastening into. For these electrical screws, it allows the flat head to sit perfectly level with the socket or switch plate for a clean appearance.

MPN stands for Manufacturer Part Number. C-SCREW50BK is the unique identifier for this specific M3.5 x 50mm Flat-Head countersunk electrical socket screw in Black Nickel/Gunmetal finish.

The product information states 'PRICE PER 1 SCREW' and 'Supplied in Knightsbridge polybag', indicating they are individually priced but provided in a bag for handling.

Ensure you are using the correct M3.5 thread size for your electrical box. Check for any debris or damage in the box's threading. The screw may be incompatible if the box is not designed for this specific type.

Confirm that the plate has a countersunk recess for the screw head. Ensure the screw is fully seated and the plate is correctly aligned. The 50mm length might be causing the plate to sit unevenly if the box depth is not standard.

Verify the required screw length for your specific socket/switch and wall box depth. This 50mm screw is intended for specific applications; a different length may be needed if it doesn't provide a flush fit.

Handle screws with care during installation. Use appropriate tools to avoid damaging the finish. If damaged, replacement screws will be needed for a consistent aesthetic.
