Set Screws Half Dog Point

What are Set Screws Half Dog Point?

Half dog point set screws are headless fasteners with a short cylindrical tip that fits into a shallow hole or slot. The shortened “dog” provides positive indexing and repeatable alignment while staying easier to assemble than a full dog point.

Why choose Set Screws Half Dog Point

• Positive indexing — the dog tip locates in a detent or slot to prevent rotation or axial slip.
• Alignment help — repeatable clocking of components to an exact position.
• Headless profile — flush fit for tight clearances and clean appearance.

Common applications for Set Screws Half Dog Point

• Collars, cams, gears, and pulleys with prepared detents
• Indexing levers, knobs, and handles
• Fixtures, jigs, instruments, and precision mechanisms

Materials and finishes for Set Screws Half Dog Point

• Alloy steel black oxide for high strength indoors.
• 18-8 / 304 stainless for general corrosion resistance.
• 316 stainless for marine/coastal environments.

How to size and specify Set Screws Half Dog Point

Order by diameter × thread × overall length and confirm the dog length matches your detent depth. Typical drives are hex-socket.

How Half Dog Point Set Screws compare to other point styles

• Half dog vs full dog — full dog suits deeper holes; half dog fits shallow detents and eases alignment.
• Half dog vs cup — dog indexes in a feature; cup relies on frictional bite on the shaft.
• Half dog vs flat — flat bears on a machined flat with minimal marking.

Installation tips for Set Screws Half Dog Point

• Drill and deburr the detent/slot to fit the dog tip; seat fully before torquing.
• Use threadlocker or a jam screw where vibration is expected.
