Functions of Craftsman 309 piece Mechanic’s Tool Set #41309
English and Metric Sizes
The tools in this tool set are available in both English and Metric sizes. As machines are now made from every corner around the world, the mechanic will be working on some machines that use bolts in English sizes, and some in Metric sizes. That will no longer be an issue as this tool set can cover either.
Quick Release Ratchets
The Quick Release Ratchets are designed with a mechanism that allows you to change sockets faster to help you finish your work quickly.
The extension bars are attached to the Quick Release Ratchets and a socket is attached at the other end. The different lengths of the extension bars allow you to reach deep seated bolts, otherwise unreachable with the standard sockets.
The standard sockets are used for easily accessible bolts. As most bolts on machinery are typically exposed, these sockets are the best ones to use.
The deep sockets are used for bolts that are not readily accessible using the standard sockets. Depending on the design of a machinery, some bolts are placed in some awkward crevice or deep end, where a long deep socket is needed.
6 and 12 Point Sockets
Both 6 and 12 point sockets are available for the mechanic. The 6 point sockets allow for a stable grasp on the bolt head, minimizing the risk of rounding the bolt head. The 12 point sockets are used whenever a better range of motion is needed specially when working in tight restricted spaces around the machinery.
Spark Plug Sockets
Spark Plug Sockets are specially designed to remove automotive spark plugs by allowing it to hold on to the spark plug, when it is loose, allowing it to be lifted out of the tight engine space around the spark plug. It is also used to be able to hold a new spark plug while installing it into the engine.
Combination Ratcheting and Open-end Wrenches
The ratcheting wrenches helps in finishing a job faster by allow the quick installation or removal of bolts. The tool does not need to be removed from the bolt or nut, as it is being removed or installed, as the ratchet mechanism automatically holds and releases the nut as it is turned.
Ignition Wrench Sets
The ignition wrench, is a wrench that has both a box-end and open-end on either ends. This two in one tool gives the mechanic a choice of using box-end for normal jobs and open-end used usually in instances with tight spaces to work on.
Some bolts have a rounded or cylindrical heads, and has a hexagonal shaped indentation. The hex bits are used for these kinds of bolts.
Hex Key Sets
Some smaller bolts with the same hexagonal shaped indentation can be installed or removed using the smaller hex keys.
Magnetic Handle with Screw Bits and Nut Driver Bits
For small bolts and screws, with typical heads such as either flat or Philips head, different sizes of screw bits can be selected, by attaching it first onto the magnetic handle. In the same way, different sizes of nut driver bits may be used on different sizes of nuts.
