.... different point types and their uses    

Very often you will find a set screw application where you can't use a locking point or even a cup point. This is where you would be familiar with the other standard wet screw point styles and their particular uses. We have listed there point styles and typical uses here for you to make the right choices.

PLAIN CUP

Use this point against shafts too hard for the knurled cup to function or where there are fine adjustments involved that do not need a locking point

FLAT

Use this one where frequent resetting of machine parts in relation to each other is required. Since the flat point causes comparatively little damage to the part against which it is sealed. It is also used as an adjusting screw for fine linear adjustments. In such cases a flat  is usually ground on the shaft for better point contact it is preferred for thin-wall applications and on top of plugs of soft metal.

CONE

For permanent location of parts Because of its penetration, it develops the greatest axial and torsional holding power. Where the point bears against materials of HRC 15 hardness at greater the shaft is drilled to receive half the cone length, sot hat penetration is deep enough for ample shear strength across the cone section it is also used as pivot in machine elements and for making fine adjustments over a limited distance. 

DOG

Normally used where permanent location of one parts in relation to anchor is desired. The dog is located in a hole drilled in the shaft. The drilled hole must match the dog diameter to prevent side play. Holding power is based on shear strenght across the dog. It is als used in place of dowel pins and against hardened members.

OVAL

This point is used for frequent adjustment without excessive deformeation of the part against which it is sealed. Also the sealing against angular serface. In our application the shaft is normally spotted to receive the point. However the oval point has the lowest holding power of all points.
