M6 Concave Screws Fender Washers Hex Fasteners 20mm Car Styling

Give engine bay panels and other suitable vehicle fittings a cleaner, more considered finish with this set of M6 concave screws and wide fender washers. The coloured washer heads add a neat styling detail around fixing points while helping spread the load across the surrounding panel surface.

Each set includes 10 steel M6 x 20 mm bolts and 10 anodised aluminium washers. The washers have a concave, countersunk-style profile with an outer diameter of 18.80 mm, an inner opening of 6.20 mm and a thickness of 4.15 mm. This broad washer shape provides more coverage than a standard narrow washer and sits neatly around the bolt head when installed correctly.

These automotive fasteners are suitable for a range of universal fitting and styling applications, including areas beneath the bonnet, fenders, headlights and bumpers. The washers are stated as suitable for 10 mm bolt holes under the bonnet, but always check the existing thread, hole size, panel thickness and available clearance before fitting. They can also be considered for suitable number plate and trim applications where the M6 size and 20 mm bolt length are appropriate.

Choose from black, red, blue, purple, silver or gold to coordinate with the vehicle’s existing details or create a contrasting accent. The anodised aluminium finish offers a bright, coloured appearance, while the steel bolts provide the threaded fixing component. Please check that the supplied fasteners are suitable for the intended load and location, as these are styling and general automotive fastening components rather than a guaranteed replacement for vehicle-specific hardware.

Installation is straightforward for anyone familiar with automotive fasteners, although installation instructions are not included. Remove the original fixing where appropriate, confirm the fit and tighten carefully using suitable tools without over-tightening. A practical choice for refreshing visible engine bay hardware, securing compatible panels or adding a coordinated finishing touch to a vehicle project.
