Description
Bulk-pack red female blade terminals for reliable automotive connections
Product Overview
The OEX ACX3016 insulated female blade crimp terminals deliver workshop-grade electrical connections for automotive, marine, and 12V accessory wiring. Supplied in a 100-piece pack, these 6.3mm blade terminals handle the heavy-duty wire sizes common in vehicle electrical systems—perfect for workshops doing regular wiring jobs, auto electricians building custom looms, or serious DIYers tackling caravan fitouts and 4WD accessory installs.
Each terminal features a double crimp design with separate crimps for the conductor and insulation, ensuring both electrical integrity and mechanical strain relief. The red vinyl insulation instantly identifies these as 2.5-3.0mm² wire terminals, eliminating confusion when you're working with multiple wire gauges in complex harnesses. Tin-plated copper construction resists corrosion while maintaining excellent conductivity—critical when terminals are hidden behind panels or exposed to underbonnet heat and vibration. The 6.3 x 0.8mm blade receptacle matches the standard automotive blade terminal size used across countless switches, relays, fuse holders, and electrical accessories.
Whether you're wiring up aftermarket lights, building a custom switch panel, installing auxiliary battery systems, or maintaining fleet vehicles where terminals regularly need replacement, this 100-pack keeps you stocked for the long haul without constantly reordering singles.

Features & Benefits
Double Crimp Design – Separate crimps for the wire conductor and insulation jacket mean proper strain relief on both elements. The conductor crimp ensures low-resistance electrical connection, while the insulation crimp prevents wire flex fatigue at the terminal entry point—particularly important in high-vibration automotive environments where single-crimp terminals can fail.
Tin-Plated Copper Construction – Copper provides excellent conductivity with low voltage drop, while the tin plating protects against oxidation and corrosion. In underbonnet installations where terminals face heat cycles, moisture from humidity, and road salt spray, tin plating significantly extends terminal life compared to bare copper.
6.3mm Blade Standard – This terminal size matches the most common automotive blade terminal specification used across Australian and international vehicle electrical systems. Compatible with standard switches, relays, fuse blocks, and countless aftermarket accessories, giving you versatility across diverse wiring jobs.
Colour-Coded Red Insulation – The red vinyl sleeve instantly identifies these as 2.5-3.0mm² wire terminals, following industry-standard colour coding. When you're troubleshooting a loom six months after installation or another electrician needs to work on your wiring, that colour-coding prevents dangerous mismatches between terminal and wire size.
Workshop-Friendly 100 Pack – Instead of running out mid-job or paying retail markup on blister packs, this bulk quantity suits workshops, mobile auto electricians, and regular installers. Keeps your crimp terminal drawer stocked for months of wiring work without tying up excessive capital in inventory.
Vinyl Insulation – PVC insulation handles automotive temperature ranges while providing adequate dielectric strength for 12V and 24V systems. The vinyl sleeve protects against shorts where terminals run close to chassis or mount brackets, and provides safe handling during installation.

Compatible With / Goes Well With
- 6.3mm male blade crimp terminals (matching wire size)
- Automotive switches with 6.3mm blade terminals
- Standard blade-type fuse holders and fuse blocks
- Automotive relays with 6.3mm spade connections
- Ratcheting crimp tools with insulated terminal dies
- 2.5mm² and 3.0mm² automotive cable (various colours)

Note: Always match terminal wire size to actual cable cross-section. Using oversized or undersized terminals creates unreliable crimps prone to high resistance or mechanical failure.
Frequently Asked Questions
What crimping tool do I need for these terminals? Use a ratcheting crimp tool with interchangeable dies sized for insulated terminals, typically marked for red/2.5-3.0mm² wire. Proper tools ensure both the conductor and insulation crimps close correctly—avoid using pliers which damage terminals and create unreliable connections.
Can I use these on 12V LED light bar wiring? Yes, provided your wire gauge is 2.5-3.0mm² and the light bar connections use 6.3mm male blade terminals. Verify current draw stays within wire and terminal ratings—these terminals suit most auxiliary lighting applications under 20A continuous load.
Will these fit standard automotive fuse holders? Most automotive blade-style fuse holders use 6.3mm terminals, so yes—these terminals connect directly to standard fuse blocks, inline fuse holders, and distribution panels using that terminal size. Always verify terminal dimensions on your specific fuse holder.
Are these suitable for outdoor or underbonnet installation? Yes, tin-plated copper resists corrosion better than bare copper, and vinyl insulation handles automotive temperature ranges. For harsh environments, apply dielectric grease to the connection and use heatshrink over the terminal for additional protection against moisture ingress.
Can I connect 2.0mm² wire if I don't have yellow terminals? While the barrel will physically accept 2.0mm² wire, proper crimping requires matched terminal-to-wire sizing for reliable electrical and mechanical connection. Use correctly sized terminals (yellow/2.0mm²) for 2.0mm² wire rather than oversizing—improper matches create high-resistance connections.
