size across corner

inside diameter and thread size

the strength of a bolt is calculated on the basis of its root diameter

the spindles of bench vices are usually provided with knuckle threads

when water tightness is the prime consideration in joints, pitch should be relatively swall

a bolt and the corresponding nut are provided with threads of the same hard and pitch

the screw and nut put together comprise a screw pair

when considering the length of bolt, the thickness of head is not taken into consideration

turnbuckie is used where slight angular displacement is required

if the nut is made of a weaker material than the bolt, then the height of nut should be more than the nominal diameter of bolt

ring nut

jain nut

sawn nut

castle nut
