One that fits the bolt very securely, preferably a 'box' wrench, that fits every'flat' and has a long handle to apply maximum pressure to it.
The function of a wrench depends on what type of wrench it is. In general, small flat wrenches have two 'flats' that are sized to particular bolt or nut sizes.These wrenches are used to loosen or tighten nuts onto bolts. The crescent wrench is able to be adjusted to many sizes of nuts and are handy to have in a tight corner when you don't know the size. Ratchet wrenches are used to do up or loosen nuts quickly where movement may be restricted and you have to re-seat an ordinary wrench after each partial turn. Box wrenches have round heads, able to completely encompass the nut and are very useful where nuts are rusted or otherwise extremely tight. Pipe wrenches are usually larger jawed wrenches used to grip large pipe nuts and pipes themselves in plumbing work.
Deep or if you can't get one long enough, a box end wrench
A box wrench has that feature.
I believe a striking wrench is a combination adjustable/hammer type of wrench used in the mining industry. I have one on hand in my tool box if you want a pic, I'll be glad to take one for you or simply look at the picture in the related link.
None really, you just have to extra careful working near finished surfaces.
Torque is not the type of bolt but a type of wrench used to tighten bolts. A torque wrench will tell you how tight a bolt is tightened like 60lb of torque or tighten to 80lb of torque so a bolt will be tight enough to stay in but not too tight that you strip the bolt.
Adjustable wrench
With some applications, yes. The beam type is best for pinion preload. The click type is best in tight places. Also, never had to recalibrate a beam type.
The cap takes a T50, I am looking for the bolt size myself. My mechanic says it is probably metric, I would really like to know before I cut the head off to yank the old tensioner. If you know, please let me know. An additional problem with this job is that the clearance is very tight, I tried to use a l-type torx wrench and a piece of pipe. The head of the bolt unfortunately was already stripped out so I am declaring war on the bolt. This agression will not stand. thanks jack
If you are referring to the type of wrench that usually has an open end to tighten the bolt or nut and a point on the other end...the point is called a "drift pin" and is used to line up the hole that the bolt is going into. That style of wrench is called a "drift pin wrench".
Type and year of car would help.
Most likely for this type of van is a 3/8 Allen wrench.
You need a torx type socket. If you use an Allen wrench...you will strip out the inside of the bolt.
RACKETS
The best lug wrench is the cross shaped type with 4 different sockets. This is the only hand wrench that will apply enough torque on your lug bolts.
I believe it's either a 40 or 45.
That depends on what type of bolt it is. Some use an Allen wrench while others have a bolt head (ie,1/2 inch or 13mm ect...) The best thing to use on a bolt head is a box end wrench, the rule of thumb is, left to take off. right to tighten. Keep in mind that you are looking at it backwards, so looking at the caliper it would be right to take off and left to put it on. Take the wrench and make sure it is on the bolt head, have the wrench straight up then take the palm of your hand and hit the wrech to your right a little at a time so you don't bust up your hands. The same will go for the Allen wrench.
