6.3mm Automotive Blade Connectors – Faston Spade Terminals & Housings
6.3mm Automotive Blade Connectors – Faston Spade Terminals & Wire Harness Housings
Yoeruyo's 6.3mm automotive blade connector range covers the most widely used quick-disconnect terminal system in automotive, motorcycle, appliance, and industrial wiring. The 6.3mm (0.250 inch) tab width is the global standard for medium-current Faston-type spade terminals, used in fuse boxes, relay blocks, motor connections, lighting circuits, and wire harness assemblies across passenger vehicles, commercial trucks, motorcycles, and white goods.

Product Variants
- Male blade tabs – flat tab terminals for crimping onto wire; mates with female receptacle connectors
- Female receptacle (spade) – push-on receptacle for mating with 6.3mm male blade tabs on relays, fuses, and switches
- Insulated variants – PVC or nylon insulation sleeve in color-coded sizes for wire gauge identification (blue: 1.5–2.5mm²; yellow: 4–6mm²)
- Non-insulated variants – bare copper alloy terminals for use with separate insulation sleeves or heat-shrink tubing
- Heat-shrink insulated – adhesive-lined heat-shrink sleeve for waterproof and strain-relief terminations in outdoor and automotive applications
- Multi-way housings – plastic connector housings accepting multiple 6.3mm terminals for organized multi-circuit wire harness assemblies
Application Scenarios
- Automotive wire harness – fuse box connections, relay block terminals, lighting circuits, and motor connections in passenger and commercial vehicles
- Motorcycle & ATV wiring – ignition, lighting, and accessory circuit connections in two-wheel and off-road vehicles
- White goods & appliances – motor terminals, heating element connections, and control board wiring in washing machines, dryers, and HVAC systems
- Industrial control panels – relay and contactor connections, circuit breaker wiring, and panel-to-field wiring in industrial enclosures
- Marine & off-road – sealed and heat-shrink variants for high-humidity and vibration-prone marine and off-road wiring
- Aftermarket & repair – replacement terminals for automotive electrical repair, custom wiring, and retrofit installations

Buying Guide – Selecting the Right 6.3mm Terminal
- Wire gauge – match the terminal crimp range to your wire cross-section (mm² or AWG); using an undersized terminal on heavy wire causes poor crimp quality and overheating
- Insulated vs non-insulated – insulated terminals are faster to install; non-insulated terminals allow custom insulation with heat-shrink or separate sleeves
- Current rating – confirm the terminal's rated current meets or exceeds the circuit's maximum load; derate for high-temperature environments
- Male vs female – male blade tabs mount on the device (relay, fuse, switch); female receptacles crimp onto the wire and push onto the male tab
- Sealed vs standard – use heat-shrink insulated or sealed variants for outdoor, marine, and under-hood applications exposed to moisture and vibration
Frequently Asked Questions
What is the difference between 6.3mm and 4.8mm Faston terminals?
6.3mm (0.250") and 4.8mm (0.187") refer to the tab width. 6.3mm terminals are rated for higher currents (up to 30A) and are used for motor, heating, and power circuits. 4.8mm terminals are used for lower-current signal and control circuits. They are not interchangeable.
Can I use 6.3mm terminals without a crimping tool?
A proper ratchet crimping tool is strongly recommended for reliable, low-resistance crimps. Plier crimping produces inconsistent results and may cause high contact resistance, overheating, or terminal pull-out under load. For production use, a dedicated 6.3mm terminal crimping tool is essential.
What wire gauge is compatible with 6.3mm terminals?
Standard 6.3mm terminals accept wire from 0.5mm² to 6.0mm² (AWG 20 to AWG 10). Always match the terminal's crimp barrel size to the wire gauge — different barrel sizes are available for different wire ranges within the 6.3mm tab family.
Are insulated terminals color-coded by wire gauge?
Yes. Standard color coding: red = 0.5–1.5mm² (AWG 22–16); blue = 1.5–2.5mm² (AWG 16–14); yellow = 4–6mm² (AWG 12–10). This matches the international IEC and automotive wiring color convention for insulated crimp terminals.
Do you offer bulk pricing for wire harness manufacturers?
Yes. Yoeruyo specializes in batch supply for wire harness production. Contact us for volume pricing, mixed-SKU pallet orders, and custom packaging options for production line integration.
