Are all the female side of the terminals the same thickness? the reason i ask because i purchased this kit to install speakers with 20awg wire.

I’m not sure what you mean by thickness of the female side. But the male blades are 0.018x0.110”, 0.018x0.189” & 0.028”x0.248”. The females fit snugly.

Will the female terminal fit a 1/4" male terminal?

there are 3 sizes, each female joins the corresponding size male. good material, solid fit. Using with 12vdc gel packs as used in UPS Battery Backup power supply. joining 2 - 12vdc batteries in series to make a single 24vdc power supply cube.

Anyone else have problems with crimping the 2.8 female terminals in the 0.5 side of the crimping tool? Only fits in the large side of tool. Poor crimp

I have the same problems most of the time with these. Looks like we have the wrong crimping tool? I use the Stakeon crimper that I have from my Industrial electrical/maintenance job.

Quick, Clean, and Super Handy Splicing Kit!

Just got the Twidec 360-piece quick splice set (2.8/4.8/6.3 mm) and couldn't be happier. It’s a total life-saver when I'm wiring my car audio, installing speakers, or messing with home electronics. What makes it awesome: Huge variety of sizes: With 360 pieces across all three sizes, I’ve always got the right fit no matter the wire job—big or small. Fast & tool-free: These splices are so quick—just clamp, snap, and crimp. No stripping, no messing around. Great when I'm in a rush. Solid connections: Once clamped, everything stays snug and secure. No loose ends, and vibration-resistant—perfect for car setups. Value-packed: For the price, getting three sizes and this many pieces in a neat organizer is a steal. Perfect for DIYers, car audio upgrades, or any quick wiring fixes. If you want fast, reliable wiring splices without the fuss, this Twidec kit’s the real deal. Highly recommend!
