Special Points

The point is the part which most characterizes socket set screws on the basis of its use and coupling material.
Some of the main variations, with references to standard points, are reported here.

Flat

A1 FLAT POINT

With dp point diameters corresponding to the root limit in order to ensure the widest contrast surface or reduced diameters in comparison with standard dp ones.

A2 FLAT KNURLED POINT

This is a special ARSER item which prevents unscrewing in presence of vibration.

A3 MARKED FLAT POINT

With a specific mark, item or customer/symbol.

A4 OVAL POINT

With a wide R radius, in order to ensure a central and reduced contact with registers/locks.

A5 BALL POINT

With a small R radius for registrations.

Cone

B1 B2 B3 B4

B1 B2 B3 B4 SPECIAL CONE

Practically all conicity angles between over 120° to 45° are produced by ARSER by means of turning, that is, with flat surfaces and minimum dp point diameters. The so-called “ARSER POINT” fears no comparison! Its conicity, along with the high-quality of its material, makes it possible to implement more reliable locks, which are particularly appreciated in the fitments sector.

B5 ROUNDED CONE (R)

For a sure contact on conicity and for registration (electrotechnical and general mechanical sectors).

B6 B7 B8

B6 B7 B8 HALF CONE

With a sharp point for fixing wires in clamps, for handles, etc.

B9 CUT OFF CONE

For registrations/locks.

B10

B10 SMALL RECESSED CONE

For handles with whole sets.

B11

B11 RECESSED CONE

For handles with half divided sets.

Dog

C1 C2

C1 C2 FLAT BASE DOG POINT

With a special dp diameter and/or z length, with sharp or champfered edge.

C3 C4

C3 C4 ANGLED BASE DOG POINT

With a special dp diameter and/or z length, with sharp or champfered edge.

C5 OVAL DOG POINT

With convex or spherical extremity of R radius.

C6 CONED DOG POINT

With cone extremity of A angle.

C7 DOG POINT WITH CONICITY

Of 2A angle.

C7 DOUBLE DOG POINT

Of diameters dp1 and dp2.

C8 SHEARING POINT

With dog and cup diameter dz for “shearing” function.

C9 DOG POINT WITH A HOLE

Of external diameter dp and hole diameter df.

C10

C10 GROOVED DOG POINT

For assembly elements

Cup

E1 CUP POINT WITH CONE

With dz and/or angle A.

E2 ROUNDED CUP

With radial bottom R and diameter dz.

E3 FLAT BOTTOM CUP

With cup of diameter dz.

E4 CUP WITH POINT

With cup of diameter dz.

E5 KNURLED CUP POINT UNI/DIN EN ISO 4029 (ex UNI 5929 – DIN 916)

This type of point guarantees locks in working conditions characterized by strong vibrations.
ARSER knurleds are produced by means of special rolling devices which result in sharp-edge toothing in order to ensure the best grip on every material.
Upon request, different pitches can also be produced.
