Impact Drivers and Wrenches

by adminpower

Impact Drivers

An impact driver is a tool that combines a high rotational torque with fast-paced rotational tapping. It ensures the screw stays in place during rotation without spinning it out of the slots. An impact driver can be confused with the traditional cordless drill. It helps open or fix screws where they tend to be stuck. It achieves this by the trigger which allows you to stop driving consistently and pushes the screw further.



An impact driver is suitable for drilling holes and fastening screws onto furniture. In woodwork where assembly of various pieces is required, an impact driver works well in holding the pieces together with screws. While putting together frames or bookshelves you need set screws to ensure they remain in place.

They are applicable in constructing cabinets, wooden tables, and bookshelves. They come in handy when fixing permanent wood frames among other wooden items.

Impact Wrenches

It is a high rotational tool for loosening rusty nuts from vehicles or complex machinery. It has a unique hex opening compared to an impact driver, allowing it to fit sockets of various sizes. It also suits great devices such as wheel nuts. The hammering mechanism of impact wrenches provides concussive blows very quickly allowing lug nuts to loosen. Most impact wrenches use compressed air in combination with lubricating systems to allow effectiveness. Electric ones are available although they present a reduction in impact.


In Automotive industry

Impact wrenches are applicable when driving out rusty or firmly fixed nuts from cars or tracks. The wrench screws out the nuts by applying a high force between the bolt and the socket allowing it to loosen. They produce a loud whirling sound when operation hence it is important to use ear plugs for safety.

They are suitable for removal of wheels, disconnection of individual car parts and replacement of worn out screws.  They also apply to maintenance of large machinery and in complex construction projects.

Difference between Impact Drivers and Wrenches

Impact wrenches are heavier and bulky. They operate with more power compared to impact drivers. Impact wrenches have a square drive measuring ½” compared to impact drivers which have a hex drive measuring ¼.”

Impact wrenches are mainly used to loosen screws and nuts while impact drivers fasten nuts by driving them onto surfaces. Impact drivers apply in situations where standard drills can’t function well, while wrenches can perform general heavy duty purposes.

Impact drivers are practical for home use since they are compact and offer more torque than the usual cordless drills. They are easier to use and friendly compared to impact wrenches. Both impact wrenches and drivers perform by exerting concussive rotational forces where it’s difficult to drill or screw using the other tools.

Bottom Line

Impact wrenches deliver extra power compared to impact drivers when it comes to function. However, most people do not find much use of this powerful tool owing to it’s applicability to complex functions.  On the other side, impact drivers are suitable for more practical work around the home. They can be converted to wrenches and used with socket drivers.

Metal Working Tools

Have you ever gone to a metal fabrication shop? It is fascinating to see how they work the various pieces of metal. Bending, cutting, welding for a variety of purposes and a variety of different metals, although steel is the most common.

There are huge machines called brakes that bend thick sheets of metal. There are small hand versions that HVAC people use to create the ducts for HVAC systems. (By the way, if you didn’t know, HVAC stands for Heating, Ventilation and Air Conditioning.) That is fine for the thin metal sheets they work with. But for thicker metal sheets or even plates, these larger machines are able to use a lot of pressure and force to bend them.

Then they have torches that they use to cut metal as well as various types of saws, particularly band saws. Some even use lasers to do the cutting. There are also shears to make rough cuts.

Then there ways to fasten the metal together. There are drill presses to make holes in the metal that you can put rivets or bolts through. Of course if you are using bolts, you need to have taps and dies to make the threads in the hole if you want that. Or you can have a smooth bore and the nut and bolt hold things together.

Besides that, to join things, you can weld them. There is arc welding and TIG and MIG welding and many more. Different types of welding are used for different purposes and for different types of metals. You have to handle aluminum differently than you do steel.

Then you need to be able to finish things off as well. So there are a variety of grinders such as belt grinders to smooth off rough spots. Then there are tumblers for deburring and polishing. And of course lathes to be able to turn rods of metal into different shapes.

If you ever get a chance to go to a metal fabrication shop while they are working, it is very interesting. Even just the machines they use to move the heavy pieces of metal around.

Window Glazing Tool

Tenants are a Pain with Panes

My tenants have broken out a couple of panes in the storm door yet again. This is the third time they have done this. They are a pain with the panes. This is an older style storm door made out of wood with small 12×13 panes. So I got the two panes and put them back in. Usually I scrape out the old window glazing with a flat screw driver and a chisel. The points are still there and I just bend them down, put the new piece of glass in and then bend them back up and put the glazing compound in.

Glazing Points

This time however, the points had come out with scraping or I did something wrong. So the glass was held in by just the new soft glazing compound which of course hadn’t hardened yet. So a day or two later the tenant called and said one of the panes had fallen out and broken.

I wasn’t sure where my glazing points were. Originally they were little flat triangles of metal that you shoved into the door frame to hold the glass in place. They were a pain to deal with. In the past, I think I broke a pane trying to get a glazing point in with a screwdriver or chisel when I was trying to push it into the wood. I must have pushed too hard the wrong way.

So, off to Home Depot to get more glass, glazing points and more glazing compound because my old little can had run out. Decided to get Plexiglas instead of glass. They don’t sell small cans of glazing compound anymore, at least at Home Depot they don’t. What I had to get will last me the rest of my lifetime and probably part of my kid’s lifetime.

Glazing Tool

OK, so this blog is supposed to be about tools. I am finally getting around to that. It turns out the guy at the store showed me a glazing tool. I didn’t know they existed. One end is flat and much stiffer than a putty knife so you can use it to push in the glazing points. The other end is bent in a 90 degree angle like a V so you can hold one side against the pain and have a nice steady angle for the glazing compound. A chisel and putty knife work just fine so I didn’t buy it.

Modern Glazing Points

When I went to put the new pane in, I was pleasantly surprised to see what glazing points look like these days. I have probably seen it before but had forgotten  about it since it isn’t something I do every day. They now have two little tabs bent out so that you can push the point in much more easily instead of trying to push in a thin little piece of metal.

So I put in the Plexiglas. On the piece of glass that hadn’t fallen out, I dug out a bit of the new soft compound and put in a point and put the compound back in place. Did that all the way around the pane. Neither one should be going anywhere anytime soon. If the Plexiglas one does, at least it won’t break.
