Description
Overview
The Coyote 04-1659 Nut Cover is designed to protect and conceal fasteners used in HVAC systems and vehicle interiors.
Because exposed hardware can corrode or collect debris, this cover keeps components clean and secure.
It also enhances the visual finish of panels, vents, and mounting assemblies.
Function and Performance
This nut cover slips directly over a standard-size nut or bolt head.
Its snap-fit design locks into place without adhesives or tools, saving time during assembly.
In addition, the tight fit helps seal out dust and moisture that could cause rust or discoloration.
As a result, the component remains both functional and visually appealing for years of service.
Durability and Construction
Coyote manufactures the 04-1659 Nut Cover from impact-resistant black polymer that withstands vibration, heat, and chemical exposure.
Because of its robust build, it stays firmly in place even in mobile HVAC systems or heavy machinery.
The smooth, gloss-finish surface cleans easily and matches the aesthetic of nearby louvers and vents.
Installation
Installation is quick and tool-free.
Simply align the cover with the fastener and press until it snaps into place.
Removal for service is just as easy — the flexible walls allow the cover to pop off without damage.
Therefore, it’s ideal for both OEM assembly lines and field service repairs.
Applications
The Coyote 04-1659 Nut Cover is used in buses, RVs, construction equipment, industrial enclosures, and HVAC systems.
It’s commonly applied to panel mounts, vent bezels, and bracketed assemblies where exposed hardware must stay protected or hidden.
Because of its universal size and simple design, it fits a wide range of applications.
