251 Piece Nylon Nut/Grommet Assortment
251 nylon nuts and grommets in a pre-packaged assortment covering the threaded and plug-type nylon fasteners used throughout domestic vehicle interiors, electrical systems, and body panels. Nylon nuts resist vibration and corrosion where steel fasteners would cause galvanic damage or noise; grommets protect wiring and hoses passing through metal panels from chafing and moisture intrusion.
What's Included
- Nylon nuts — threaded nylon fasteners for trim, panel, and electrical attachment where metal would corrode or cause noise
- Grommets — nylon or rubber plugs for protecting wiring, cables, and hoses at panel pass-throughs
- Multiple sizes covering common domestic vehicle applications
- 251 pieces total

Best For
- Auto body and trim shops — nylon nuts are used throughout interior panels and trim brackets; grommets are replaced whenever a wiring harness or hose is rerouted through a new panel hole
- Electrical and wiring specialists — grommets are a code-required element wherever a wiring harness passes through a metal panel edge; this assortment keeps common sizes in stock
- Fleet maintenance shops — nylon grommets and panel nuts are high-consumption items on commercial vehicles that see regular interior teardowns for electrical and HVAC work
Nylon Nuts vs. Grommets — What Each Does
Nylon nuts function like standard hex or cap nuts but are made from nylon rather than steel. They're used where a metal nut would corrode in contact with dissimilar metals (galvanic corrosion), where metal-to-plastic contact would create squeaks or rattles, or where electrical isolation between the fastener and the panel is needed. Common applications include dash trim brackets, interior panel clips, and battery cable management points.
Grommets are ring- or plug-shaped rubber or nylon inserts that fit into a hole in a metal panel. They protect cables, wires, or hoses from chafing on the sharp panel edge and provide a weatherseal at body and firewall pass-throughs. A grommet that splits or falls out leaves wiring exposed to abrasion — one of the more common causes of electrical faults on older vehicles.
