Types of Automotive Fasteners
Here are the Types of Automotive Fasteners, their series classification, and common applications…
Fastener Type |
Main Characteristics |
Typical Applications |
| Car Bolts | High-strength threaded fasteners; used with nuts/washers | Engine assembly, chassis, suspension, structural joints |
| Screws | Self-tapping or machine thread; used for lighter assemblies | Interior panels, dashboards, electronics, plastic components |
| Nuts | Various locking styles (standard, flange, lock nuts) | Used with bolts in frame, body, and mechanical assemblies |
| Washers | Distribute load, prevent loosening, protect surfaces | Suspension, brackets, engine covers |
| Studs | Threaded on both ends; permanent installation | Cylinder heads, exhaust manifolds, turbo systems |
| Rivets | Permanent, vibration-resistant fastening | Body panels, doors, interior parts |
| Blind Rivets (Pop Rivets) | Installed from one side only | Sheet metal, body repair, lightweight structures |
| Clips (U-Clips / Spring Clips) | Quick fastening for plastics and thin metal | Bumpers, trim panels, door panels |
| Push-in Rivets / Plastic Rivets | Tool-free installation; used in plastics | Car interior, splash shields, underbody panels |
| Retainer Clips | Hold cables, hoses, and wiring in place | Engine bay, trunk, wiring harness |
| Panel Fasteners | Connect body panels quickly, often reusable | Wheel well liners, trunk panels |
| Snap Fasteners | Provide quick-release for covers and trims | Seat covers, soft materials, interior assemblies |
| Threaded Inserts (Rivnuts/Nutserts) | Provide threads in thin materials | Metal sheets, hollow components |
| Self-Tapping Screws | Create their own threads; ideal for plastics | Interior parts, electronics, dashboards |
| Self-Drilling Screws | Drill and fasten in one step | Metal body repair, custom installations |
| Hose Clamps | Tighten hoses around pipes or fittings | Cooling systems, fuel lines, vacuum systems |
| Pins (Cotter Pins, Clevis Pins) | Safety locking, non-threaded mechanical joints | Suspension joints, axles, pedal assemblies |
| Snap Rings / Circlips | Retain components on shafts or inside bores | Transmissions, gear systems, bearings |
| Studs & Wheel Lug Nuts | High-strength threaded fastening for wheels | Wheel attachment and safety-critical joints |
| Automotive Specialty Fasteners | Designed for OEM-specific functions | Door lock rods, seat belt bolts, airbag fasteners |
