there is nothing wrong with the Halfords socket/spanner sets
Dan Punchard:
Halfords tools ? Now that’s worrying no wonder bits fall of vehicles,not trying to boast here but any one who uses anything less than facom ,king ■■■■,britool,Bedford ,ect should stick to push bikes,I can see that halfords tools might get a driver out of trouble but really that’s the limit.
so, from that part that i have highlighted, are you suggesting that parts are regularly falling off my vehicles? 
for your information, and whoever else cares to enter the debate, i have successfully changed the head gaskets on numerous DAF XF’s using the Halfords socket set i have, admittedly, i have used a couple of other tools also, such as a large breaker bar to crack the head bolts, but, once cracked, back to the trusted Halfords 3/8 drive socket and ratchet, all the other bolts and nuts, Halfords spanners
let’s face it, a spanner is only as good as the tool holding it 
i have had Britool, Facom, Snap-on and Halfords, they are all about the same
they all boast a ‘Lifetime Guarantee’ these days
have you tried exchanging a Snap-on spanner under guarantee recently?

Halfords on the other hand, just take it back, they will ask for the receipt and swap it without question
