1. Types of Fasteners Commonly Used in the Automotive Industry
Bolts and Nuts: Used for engine, chassis, and body structure connection, such as high-strength wheel bolts and cylinder head bolts.
Self-tapping screws: used for plastic parts, interior panels, wiring harnesses fixed to reduce the need for pre-drilling.
Rivets (solid/pull-out): used for body sheet metal connections to improve vibration resistance.
Clips and plastic fasteners: for non-structural fixing of interior trim, bumpers, seals, etc.
Threaded inserts: to enhance the thread strength of plastic parts, such as sensor brackets, ECU housings.
2. Customized automotive fasteners
Non-standard size bolts or nuts: shaped head (such as oval, square, flat round head, etc.); extended threads, shaped screws; special surface treatment (Dacromet, electrophoresis, zinc-nickel oxide alloy, etc.)
Specialized materials: high-temperature-resistant stainless steel (e.g., AISI 304/316); ultra-high-strength steel, alloy steel, titanium alloy; high temperature-resistant stainless steel (e.g., AISI 304/316); ultra-high strength steel alloy steel, titanium alloy; corrosion-resistant and lightweight materials
Composite structural fasteners: metal and plastic combinations, sealing gasket-integrated bolts, fasteners with torque control
Functional fasteners: anti-loosening, anti-vibration, anti-theft design; built-in spring structure, break-off screw design; removable/reusable structural parts.
