Product Information
Full details
The uxcell Countersunk Washer is an essential hardware component designed for DIY enthusiasts, hobbyists, and professionals who need a secure, flush-mount solution for M5 flat head screws. These washers provide a professional-looking finish and improve load distribution for assembly projects, though users should ensure their project specifically requires a 12mm outer diameter to avoid clearance issues with surrounding hardware.

FAQs
Are these washers compatible with M6 screws?
No, these are strictly sized for M5 screws with a 5mm internal diameter.
Can these be used outdoors?
Yes, but if the environment is wet or salty, regular maintenance is recommended to maintain the finish.
How many washers come in the package?
Each package contains 12 individual washers.
What is the material finish?
These washers have a black finish, suitable for matching dark-colored hardware.
What is the thickness of the washer?
Each washer is 3mm thick.
Will this work with wood screws?
These are designed for machine bolts; while they may physically fit some wood screws, they are best suited for M5 flat head hardware.
Troubleshooting
Screw head sits too high above the washer
Ensure the pilot hole is properly countersunk to accommodate the angle of the flat head screw.
Washer spins during tightening
Hold the washer firmly in place while starting the screw, or ensure the mounting hole is not overly large for the bolt diameter.
Washer does not sit flush against the material
Check for burrs or debris around the mounting hole and clear them away before installation.
Pros and Cons
Pros
- Provides a clean, flush-mount finish
- Prevents surface deformation by distributing pressure
- High-quality, durable material construction
- Versatile for use in multiple assembly types
Cons
- Specific 12mm outer diameter may not fit tight recessed areas
- Limited pack size of 12 pieces
- Not intended for high-tension load-bearing structural bolts
Setup, Compatibility & Care
To install, place the washer onto the shaft of the M5 screw before inserting it into your workpiece. Ensure the flat side faces the material and the countersunk side faces the head of the screw. These are exclusively compatible with M5 flat head bolts; they will not function correctly with pan head or hex head screws. For care, simply wipe down with a dry or slightly damp cloth to keep the black finish looking new. If the environment is highly corrosive, consider applying a thin layer of machine oil or a rust-preventative spray to the threads and washer surface.
