For maximum traction.
It cools and lubricates the metal and makes a smooth thread.
The normal racing tyres are slick and have no tread. The intermediate tyre has a 2.5mm tread, and the full wet has a 5mm tread.
because it causes smooth pening and closing operation
No thread meand more of the tire contacts the pavement which will give maximum traction
A thread chaser is used to clean the thread marks in a drilled hole or bolt cavity. It should be used with a lubricant to make sure the threads are smooth and clean, before restoring the rest of the pieces.
The fibrous surface of the jute thread has high friction, so the knot doesn't slip easily. Silk thread is smooth and has low friction, so the knot may easily slip - the same goes for nylon thread.
Silk makes a very smooth fabric, and is used to make fabric because of this. The reason for the smoothness is partly because of the tightness of the weave, and the fact that silk, or rather, the silk thread, is smooth itself when put into comparison with wool, which has a thread covered in miniature hooks. Silk has no such hooks.
The Scottish expression "like a knotless thread" means something that is smooth, easy, and effortless. It implies that a task or situation is simple and straightforward without any complications or obstacles.
To make it stand, she holds it, to make it smooth, she licks it, to make it enter, she pushes it in....it's not easy to thread a needle.
The rear wheel nuts are both right-hand thread, and you hold them on with cotter pins. The left-hand thread is on the nut for the front left wheel.
No!!! It would depend on the year early 1960 Dodges had reverse threads on the drivers side.
Screws are better. A nail is basically a long smooth cylinder, whereas a screw has a thread cut into it which provides better grip.
