  Surface measuring instruments Source: IndiaMart It is used as a measuring device to measure the accuracies in alignment, eccentricity of the parts/components. Dial indicators are also great for checking crankshaft run out, crank end play, shaft thrust, and gear backlash, flywheel face run out, flywheel housing concentricity, valve seat concentricity or piston deck clearance. Dial gauge Source:Mechanical Walkins Source: Learn mechanical "A dial gauge is like a fine watch. It consists of a graduated dial, pointer, plunger and a clamp. It measures the displacement of its plunger on a circular dial by means of a rotating pointer." Source: Technology student  It works on the rack and pinion principle. The stem/plunger has rack Teeth. A set of gears engage with the rack. The pointer is connected to a small pinion. The small pinion is independently hinged. i.e. it is not connected to the stem.  Source: Dasqua Tools The vertical movement of the stem is transmitted to the p...

  Removal of Damaged Fasteners and Replacement Removal of broken/spoiled headed screw In automobile,   Source: nykyho82 due to jerk, vibration and corrosion screws get broken. It ultimate it leads to dislocate the assembly. It is necessary that it should be removed and replaced. Similarly improper uses of screw drivers with its snap head, screw head get spoiled. It becomes difficult to tight, loosen and removal of screw from the assembly. Method of removal of damaged screw Case 1: Removal of spoiled headed screw Source:Pinterest • If the screw driver slips, due to widening of groove/screw way • Use hacksaw blade and dress the groove • Now use screw driver of thick snap and turn anticlockwise • This removes the screw, if it is not responded • Take a prick punch and hammer.  • Now drill it at the centre of screw, now 100% screw will be removed Case 2: Removal of unheaded screw • If the screw is broken at the top of the assembly • Remove the other screw a...

In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed. Automotive nuts, one of the important types of auto fasteners are usually square or hexagonal shaped metal having a threaded hole which is used for screwing a bolt that hold together temporary or permanent structures through which bolt passes.
