Dog Point Screws

Custom and Special Dog Point Screws

Pattern Fasteners manufactures standard, special and custom dog point screws for industrial and engineering applications.

Dog point screws feature a reduced-diameter cylindrical tip at the end of the threaded section. This projecting point can locate within a drilled hole, slot or recess, helping to position components accurately while providing secure fastening or controlled movement.

We manufacture dog point screws to customer drawings, existing samples and bespoke specifications, with close control over thread form, point diameter, point length, overall dimensions, materials, hardness and finishes.

What Is a Dog Point Screw?

A dog point screw differs from a conventional flat or pointed screw because the end incorporates a cylindrical projection with a flat tip.

The dog point can engage with a matching hole, groove or slot in the mating component.

Depending on the assembly, this can provide:

• Positive component location

• Accurate alignment

• Resistance to sideways movement

• Controlled sliding or rotation

• Repeatable positioning

• Secure engagement without relying solely on friction

Dog point screws are commonly used with shafts, collars, gears, sliding components and precision mechanical assemblies.

Custom and Non-Standard Dog Point Screws

Many applications require dog point dimensions that are not readily available as standard components.

Pattern Fasteners can manufacture dog point screws with:

• Metric and imperial threads

• Standard and non-standard diameters

• Coarse and fine thread pitches

• Bespoke overall lengths

• Custom dog point diameters

• Custom dog point lengths

• Fully or partially threaded designs

• Specialist head and drive types

• Tight dimensional tolerances

• Cross drilling and secondary modifications

• Specialist materials

• Heat treatment and controlled hardness

• Protective and decorative finishes

Components can be manufactured from your technical drawing, existing sample or individual specification.

Dog Point Grub Screws and Set Screws

Dog point geometry can be incorporated into a variety of screw designs.

This includes headless dog point grub screws, as well as headed or other specialist screw configurations where a projecting locating feature is required.

The most suitable design will depend on how the fastener is installed, the required thread engagement and the way the dog point interacts with the mating component.

Typical Applications

Dog point screws are particularly useful where a fastener needs to provide both secure retention and accurate location.

Typical applications include:

• Locating gears on shafts

• Retaining collars

• Positioning sliding components

• Engaging with machined slots or grooves

• Alignment of mechanical assemblies

• Machinery and production equipment

• Automotive assemblies

• Precision engineering

• Adjustment mechanisms

• Specialist industrial equipment

In some applications, the dog point can provide a locating function similar to a pin while retaining the adjustability and removability of a threaded fastener.

Dog Point Screws vs Cone Point Screws

The geometry at the end of the screw has a significant effect on how it interacts with the mating part.

A dog point screw has a cylindrical projection intended to locate within a corresponding hole or recess.

A cone point screw has a tapered point that concentrates contact over a much smaller area and can provide stronger penetration or positional locking.

Choosing between them depends on the required location, holding force, movement and mating component design.

Materials and Heat Treatment

Dog point screws can be manufactured in a range of materials to suit different strength, wear, corrosion and temperature requirements.

Options may include:

• Carbon steel

• Alloy steel

• Stainless steel

• Brass

• Aluminium

• Titanium

• Specialist and non-ferrous alloys

Heat treatment and controlled hardness can also be specified where increased strength, wear resistance or mechanical performance is required.

Finishes

Protective or decorative finishes can be incorporated into the manufacturing specification, including:

• Bright zinc plating

• Chemical black

• Phosphate coating

• Tin plating

• Chrome plating

• Customer-specified coatings

The appropriate material and finish will depend on the operating environment and performance requirements.
