Anyone building a tool kit from scratch hits this question fast. Do you start with a spanner set or a socket set? Both live in every mechanic's toolbox, but they solve different problems, and knowing which one to buy first can save you money and frustration when you're just getting started.

What a Spanner Set Actually Gives You

A spanner set is built for speed and access. Each spanner is a fixed size, open at one end or ringed at the other (or both, in the case of a combination spanner), and it slides onto a bolt from the side rather than dropping over the top.

That makes spanners the right call when:

• You're working on a bolt with limited clearance above it, like a line fitting or bracket tucked against a firewall
  
• You need to quickly loosen or tighten something without swapping attachments
  
• You're doing light, repetitive work where speed matters more than torque
  

A ratchet spanner set takes this a step further by adding a ratcheting box end, so you get the side-access benefit of a spanner with the speed of a ratchet, without needing to fully remove and reposition the tool between turns.

What a Socket Set Actually Gives You

A socket set works differently. Instead of sliding onto the bolt from the side, a socket drops straight over the top of the fastener and locks in with a ratchet handle. That top-down grip means:

• More torque with less effort, since the ratchet handle gives you leverage a spanner can't match
  
• Full contact around the fastener head, which reduces the risk of slipping on a stubborn bolt
  
• Faster repetitive turning, since you don't need to lift and reposition between strokes
  

This is why most wheel nuts, engine mounts and anything torqued down hard at the factory get handled with a socket and ratchet handle rather than a spanner.

So Which Should You Buy First?

If your budget only stretches to one set right now, think about the work you'll actually be doing:

• Buy a socket set first if you're mostly doing general maintenance — oil changes, wheel removal, engine bay work — where speed and torque matter most and clearance usually isn't tight.
  
• Buy a spanner set first if you're working on machinery, plumbing fixtures or older vehicles where fittings are cramped and a socket simply won't fit over the bolt.
  

Most tradies and serious DIYers end up owning both within their first year, because the two tools cover each other's weak points. A spanner gets into places a socket can't reach; a socket gets more torque than a spanner can safely apply. Start with whichever matches the job you're facing this week, then fill the gap once you hit a bolt the first set can't handle.
