2012 04 24 nbsp 0183 32 hello had some leaking from my 90hp Johnson was leaking from exhaust gasket under lower cowling so i took a look and tightened the 6 bolts and one of them spun and it not threading guess it corroded bolts not broken this mean i need to remove PH or can i try a longer bolt any thoughts thxThe reason for this is that dirt gets stuck in the bolt threads and it gets trapped when you start tightening the bolt making it harder to turn This is a warning sign – if you can t finger tighten a bolt until it s snug then there is something wrong Take it out and clean the threads Put a little grease on the threads before you try again It s a bad bad idea to get out spanners Cross threading occurs when the threads of a bolt shift off center and cut into the threads of a threaded hole or nut The cross threading damage caused by the bolt occurs in the top threads of the threaded hole or nut Cutting new threads on the cross threaded bolt and the damaged threads will repair the damage 2016 06 22 nbsp 0183 32 The TIME SERT Universal Head Bolt Thread Repair Kit for first time repairs come with fixture plate alignment tool a drill counterbore bit tap installation driver metal rule stop collar lube threadlocker and more Keenserts Keyed threaded body insert Thick wall design delivers highest strength for a given bolt diameter Uses conventional easy to source taps 2020 04 29 nbsp 0183 32 This bolt will contract and cool off allowing you to easily make your extraction Shake the Bolt This process will work if your bolt is not too jam packed inside You can use a socket and a ratchet to slowly move the bolt back and forth This will loosen up the bond between the threads of the bolt and the hole See the video tutorial
The easiest way is to pick up a bolt and thread checker as these will tell you what size and format fastener you re holding If that isn t an option you need a set of vernier calipers so you can measure the diameter of the threads to see if it is a parallel 2021 10 31 nbsp 0183 32 If the hole made for the bolt is not sufficiently deep the bolt will not tighten You may need to drill a deeper hole for the bolt To do this get the bolt out measure its length and work with that as you make the hole deeper Jiggle the bolt around While doing this you may find an angle that allows the bolt to get fastened Answer There are several options still available if a self tapper in metal simply go to the next larger gauge self tapping screw if the thread is a machine screw a metal thread screw or bolt then examine the screw and the hole carefully to see whether the threaded hole is stripped 2005 11 09 nbsp 0183 32 If other bolts won t thread in either then there is trouble with the hole threads and you need to chase those threads with the proper tap set Go to your local hardware store and take the bolt down there that is supposed to fit so you can get the proper bottom tap so that you can chase most of the way down the thread point in the car An Impact gun hammers the bolt as well as twists it this loosens the corrosion between the threads An impact tool will remove the bolt in seconds and you won t need to lock the blade But if the bolt head is rounded the impact tool is of no use You ll need a different solution
A related idea is to fit a spring inside the nut which firmly grasps the bolt threads and is designed to move in the opposite direction of the nut if vibration or other forces cause it to unwind Nylon inserts cannot be used in harsh chemical or high heat applications and typically can t be reused because the bolt threads cut grooves into the nylon diminishing its ability to hold after re 2019 08 19 nbsp 0183 32 Ease the flat head of the screwdriver under the bold and push it upwards Once the bolt springs free remove it replace it if it s the wrong size and fix it Use a Pair of Pliers Grab the bolt head with the pliers and pull and twist at the same time This will help yank the spinning bolt out Thread galling occurs during installation when pressure and friction cause bolt threads to seize to the threads of a nut or tapped hole It is also known as quot cold welding quot Once a fastener has seized up from galling it is typically impossible to remove 2011 08 29 nbsp 0183 32 Stuck hardware occurs when a bolt nut or screw gets corrosion between the threads and they won t budge Many times this leads to breaking the bolt off and having to drill and re tap the hold or trying to remove it with a bolt extractor I won t even mention what happens when the drill tap or extractor breaks off in the same hole Below are my top 10 2010 06 22 nbsp 0183 32 If yours is still there you can do what I did to tighten mine up I used a 8x1 25 bolt about 60 mm a nut and a washer Thread the bolt in by hand as far as you can to engage as many threads as possible then tighten the nut against the insert to reset it You put a wrench on the bolt to keep it from spinning and use another wrench on the nut to apply force to the
