That ride in your garage won't fix yourself and you won't be much good either if you don't have a good set of auto mechanics tools. There're tools for every occasion, but you don't need every tool under the sun to take care of your regular maintenance. You can do most of the basics to intermediate repairs with about 10% of the tools in the market. Knowing which tool you'll need for a task, what it does, and where to buy it can save you a lot of time and money during maintenance and repairs.
Hammers - There're atleast 6 types of hammers that I'm aware. Lets keep our discussion to 3 essentials for now.
This is one is the most common, that's called Claw hammer & mostly proffered by carpenters.
This is called Ball Pein hammer & mostly proffered when closing rivets
This Sledge hammer is the one that really drives the punch. Basically used to knock off or shear metals with metal cutter.
For more information on different types of Hammers, pls go through - Different types of hammers - what there are, and what each type is designed for.
For general household garage needs, one need not have all 3 of them; probably buying a hammer based on most common work would be of great. For example, if one uses hammer only for garage needs, the sledge hammer is more than sufficient to carry out all rounder needs.
Screwdrivers - There're 2 common types of screw driver heads.
Philips head (star screwdriver in more colloquial term)
Keep both the types of screwdrivers handy. There're screwdriver set available in the market that contains sets of 2 to 2 dozen. While 2 set screwdriver is quite low, 24 of them sounds too much for a house or house garage need. One can opt for 6-10 pieces depending upon the work involvement.
Alternatively, there're magnetic ended screwdrivers with interchangeable bits available & they're called retractable screwdrivers. When buying them, make doubly sure that the end of the driver has a strong magnet to hold the bits. Sometimes the magnet end will be handy enough to pull some washers, bolts & nut if they're struck out of reach for fingers.
Allen Key or Hex Key
A hexagonal or hex screw head has a hexagonal hole turned by a Allen key. An Allen key is a hexagonal shaped wrench.
Here's the complete list of allen key type heads
Also Hex Keys are available with bits
Have a good set of hacksaw blades for cutting down plastics, metals & wood. There're several types of handles available, use the one that is most comfortable & for all rounder usage.
Ratchet & Sockets
If there's a pleasant way to remove a nut, then it has to be with Ratchet & Sockets. These are best one than wrenches under certain situations to remove open those stubborn nuts. The best part is that ratchets can be used for both tightening as well as removing the nuts using the locks on the ratchet head.
Ratchets also have extensions through which the sockets can be attached to the extension ends so as to drive the nuts in depth.
Though Ratchets & Sockets can be bought as individual units ranging metric sizes from 5 to 25 (or may be even upto 28), it is economical to buy them as ratchet & socket tool kit.
Extensions - In a standard socket/ratchet too kit, there're limited number or no extensions available. On such cases, it is always better to buy a over & mid size in handy.
Wrench - These are the most common tool to fasten or remove nuts. Basically there're two types of wrenches. Open ended & close ended/rounded/box end. Higher quality wrenches are typically made from chromium-vanadium alloy tool steels and are often drop-forged. There're several types of wrenches to choose from
Open ended only - The benefit here is that each open ended have different metric/standard sizes. For example, one can cover sizes, 6/7, 8/9, 10/11, 12/13, 14/15, 17/18 using just 6 wrenches. The draw back being the box ended not available.
Combinations - The benefit here is that each wrench has open end & box ended on the same metric/standard size. For example sizes, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 would require 10 wrenches. The greatest benefit being is that, even the stubborn or rusted nuts can be easily removed using the box ended.
Though wrenches can be bought as individual pieces, it is economical to buy them as wrench sets. Though a little expensive, its is always better to buy combination wrenches than open wrench. Reason being that, though open ended can do the job, sometimes stubborn nuts tend to shear off due to metal bonding & box ended are the best to do the job in those situations.
