Repetition, rehearsal, exercise, preparation, training, run-through, and drill.
109*1 = 109 and 109*10 = 1090 are two.
if the diameter 5/16 inches then you covert the 5/16 into 0.3125 inches. divide 5 by 16=0.3125 which is a little bigger than 0.3! ;)
109 is a prime number, so 1*109 = 109, but no other whole numbers will work.
109 - 60% = 109 x (1 - (60/100)) = 109 x 0.4 = $43.60
Your meaning is not clear. - If you are going to tap the threads in, use a 7/32 drill bit. If you want a hole that this bolt will slip through, use a 9/32 drill bit.
Not unless it was reasonably loose. Usually when faced with this, I drill into the bolt with a very hard drill bit a tiny bit thinner than the bolt - ie if it's a 3/8 bolt, I drill in first with a 1/8 drill to create a guide hole, then after with a 5/16 drill to cut right through, yet not harm the threads. You have to be very careful to stick to an exactly straight course. After the hole is cleared, I pull the threads left from the bolt out as far as I can, then use a 'clearance' tap of bolt size to re-tap the hole.
You drill the bolt out that is snapped off in the engine,with drill bit made to drill through metal. Then use a thread maker,tap. Auto parts stores carry these. I no u can get at autozone. The tap makes new threads.
Cut the bolt head off with a cutting wheel then use a drill to drill out the bolt.
If you want the bolt to slide through the hole a 5/16 hole will work well.
The best way is to use a drill bit for metal and drill a small hole in the bolt. then use an extractor to back the broken bolt out.
Take bolt apart take bolt head and clamp in a drill press use a 3/32 drill bit to drill it out shouldn't have to drill all the way out . Numrichs brownells and midway usa have the ejector the spring and the retaining pin
Remove the broken bolt and replace it with a new one. There are several ways to remove that broken bolt. You can remove the valve cover and weld a nut to what is left of the bolt, wait for it to cool off then unthread the broken bolt. You can also drill out the center of the broken bolt and use an easy-out. You can also drill into the broken bolt with a left handed drill bit, sometimes the drill bit will catch and spin out the broken piece. I would go with the first suggestion.
Depending on the type of drill BIT, it may drill through almost anything.
drill it out with a power drill
You drill the proper size hole in to the bolt and remove it with an E-Z Out.
a good way to remove a metal bolt is to get a screw extractor. You drill a small pilot hole down the middle of the bolt, and lightly tap the extractor into the hole. The bolt will then twist out. You may need to add lube to the bolt if its rusted (WD-40 etc.)
