Automotive Hand Tools: Common Wrenches

Now you’ve fulfilled your lifelong goal of buying your own car. While many Filipinos tend to buy new, more often than not, many car enthusiasts will buy used. they’ll often find themselves scratching their heads when it comes to buying the tools they need to start working on their cars on their own.

As such, here’s our guide on the different automotive tools and equipment that’ll make your life easier. We’ll also be covering some other more advanced tools that will need a bit of familiarity to use and will only be used in really advanced projects.

Before we talk about the automotive tools list themselves, let us first list their different classifications or groups. There are the screw drives, the wrenches, and the keys.

Screwdriver or screw drives is a tool used to install and remove screws. Wrenches are used to turn objects using torque. Other wrenches are used to stop objects from turning. Lastly, keys are similar to screwdrivers that they are used to turn objects while also using leverage like a wrench.

Open-End Wrench

Box-end wrenches are the opposite of open-end wrench in that their ends come with a closed opening that wraps around bolts or nuts. Typically, the interior sides of the ring of these wrenches come with ridges that are meant for use on hexagonal bolt heads.

There are other box-end wrenches for different bolt heads like the eight-point wrench for square nuts and bolts, and twelve-point wrenches for bolts with more sides.

Usually, box-end wrenches’ ends are off-set from the handle. This provides easier access to a nut or bolt. Another usual feature of box-end wrenches is that they’re usually double ended typically with the other end a size smaller.

As the name implies, these are the opposite of box-end wrenches because the part that grips the nut or bolt is open. Like the box-end wrench, the open-end wrench is also double-ended and features a bigger or smaller sized opening at the other end.

Unlike the box-end wrench tough, the open-end wrench doesn’t have an off-set handle but the open ends are typically angled about 15 degrees for more range of movement in tight spaces.

A combination wrench like the first two wrenches are double-ended but with one end being a closed, box-end wrench, and the other is an open-end wrench.

Usually, both ends of a combination wrench are the same size.

While not common in the Philippines, flare nut wrenches are similar to a box-end nut but the part that holds bolts and nuts is not entirely closed. It’s opening though is narrower than an open-end wrench and it has a “jaw” which increases contact with the nut or bolt.

In automotive repair, its commonly used to secure brake and clutch lines as well as fuel pumps and temp sensors.
