The cat 5 cable pushes in very easily (making sure all wires are exactly the same length and exactly 12.5mm long).
Once crimped they fit snugly into the router/computer socket. I had a practise with one and tried to pull it out much harder than I would as a test, it did not come out of the computer socket.
I also gave the cat5 cable a hard pull trying to dislodge from the RJ45 once crimped, it did not budge.
I used the screwfix crimp tool (22799) as this had much better reviews than the cheaper one (30318). However, I did not use the wire stripper part of the crimp tool as it was not sensitive enough (and often left bare pieces of wire showing) I used normal wire cutters.
Rated with 4 stars as I have no other RJ45's to compare it to."
"These connectors were fitted to cat6 cables with ease. The retainer clips on the plugs don't immediately engage so they needed a bit of persuasion and a quick pull to confirm that they were properly plugged in. Otherwise ok and at a good price."
"As per previous reviews the locking into the socket is weak.
Main point to note is that these type of plugs are for stranded wire. You can tell this by the two points on the metal crimp piece and not one point for stranded cable. If you get it the wrong way round you will have bad connections.
Note to screwfix don't sell solid core Cat5 cable then sell strand type crimps. More detail required in your product information!"
"When fitting the RJ45 connector into my Pc’s network card, it jammed and broke. I thought I'd damaged my card. I got some more as it might have been a duff connector. The whole pack was the same and after closer inspection with other better made RJ45, I could see the problem. It is poorly shaped and cooper contacts were a problem too. I have tested this and other connectors (in brand new pack) on 3 other PC devices I have and the same issue. I tried on a BT new router and again it was totally wrong shape to fit"
"Very difficult to push wires into the connector head; often results in no contact after crimping and a bad cable once tested. Connector clips loose and cause connector not to "click" into NIC or patch panel.
"Could not get them to work I have a crimping tool and network tester. Use a full pack of 10 not one worked Think it's a case of crimp to hard and you push the contacts to far down so they don't make contact when inserted in socket But if you don't press hard no contact is made with the wire"
"great value, but i have almost gone through the complete pack trying to make up a connector, finally got one to work and it has lasted a couple of months and started playing up, made loads before using other connectors and no problems.
they are very lose in the socket and dont make connection properly, bought a decent 10m pre made cable, plugs are a tight fit and it works!
these got me out of a fix but are useless for long term use"
