Brake line wrenches (flare nut wrenches or simply line wrenches) serve a specific purpose. Domestic cars often use 7/16-inch and imports 10 mm. Brake line wrenches (often called flare nut wrenches or simply line wrenches) serve a specific purpose in a mechanic’s toolbox.



What are ignition wrenches?


Ignition wrenches are small wrenches used on engine parts and other automotive applications. They are designed with an angled head, allowing for access in tight areas.



What happens if you dont use a torque wrench?


Too tight and something will break, it may be the thread on the bolt, or much worse the thread on in the hole. Bolts will also break, sometimes leaving a very hard to remove bit in your frame. Not tightenough and it will work loose, and then you know to do it a bit tighter next time.



What is a good torque wrench to buy?


If you plan to do any major work on your engine or on some major powertrain components, you absolutely need a torque wrench. Overtightening cylinder-head bolts, for instance, can easily cause expensive damage and catastrophic coolant loss. Too-tight exhaust manifold bolts can cause the manifold to crack.



What are the three types of spanner?


Wrenches and spanners are ultimately designed to do the same job – tightening or loosening nuts and bolts. While this can sometimes lead to confusion between them, they’re actually two separate tools with their own characteristics and specific uses.



What are the different types of spanner?


A Very Useful Mechanics Tool

If you are working with any type of fitting that is in-line – such as a brake line, fuel line, or any type of cable – a line wrench can be a life saver. Standard open end wrenches may not grip the hex well enough, which can lead to stripping – a real pain in the neck!



What does a strap wrench look like?


Definition of open end wrench

: a wrench with jaws having a fixed width of opening at one or both ends of the handle.



Who invented the spanner?


ring spanner in British English

(rɪŋ ˈspænə ) a type of spanner with a handle that has a hole of a particular shape designed to grip a nut or bolt head. Collins English Dictionary.



Why wrenches are preferred over spanner?


Torque or turning effect due to a force is maximum when r is maximum. We prefer to use a wrench with long arm because when the length of the arm(r) is long, the force (F) required to produce a given turning effect ( x ) is smaller. Hence, a nut can be unscrewed easily.



Do you torque the nut or the bolt?


In simple terms, you need torque to create tension in a bolt. You use torque to turn a nut onto a bolt and then to stretch the bolt, making it a solid spring that clamps the two materials together.



How do you use a spanner with a torque wrench?


Torque wrenches are a type of wrench commonly used in automotive work and other tasks where a precise torque setting is needed for a specific bolt. Ratchet wrenches are more simple wrenches designed for loosening and tightening bolts.



How does a crow’s foot affect torque?


An invaluable tool for engineers, the torque extension app calculates the exact torque wrench setting value for required level of torque to be applied. When you put an extension on a torque wrench (e.g. a crow foot or a dog bone) the torque applied to the fastener increases as the lever arm extends.



What is a torque multiplier wrench?


A torque multiplier is a tool that provides a mechanical advantage when loosening or tightening nuts and bolts. They’re used to increase the amount of applied torque, allowing workers to rapidly assemble or disassemble heavy machinery, vessels, and structures.



How often do torque wrenches need calibration?


In short, it’s standard practice to calibrate your torque wrench every 5,000 cycles or every 12 months, whichever comes first.



Can you use a universal joint with a torque wrench?


You cannot get an accurate torque with a universal joint in between the bolt and the torque wrench, there are more factors than just the angle you have to consider.



What is the most accurate type of torque wrench?


Dial-type torque wrenches are generally considered to be one of the most accurate types of the torque wrench. The dial-type wrench is the only type of torque wrench where the final reading is not easily affected by the hand-hold position on the wrench.



What does a flare nut look like?
