Square Head Set Screws

Square head set screws are a specialty type of socket set screws that feature a distinct square head set on a fully threaded shaft. These robust fasteners are highly versatile for use in the machinery, automotive, and industrial sectors. Installation is completed using a square driver or wrench, which provides a more secure grip and improved torque control compared to a hexagon tool. Square head set screws are commonly installed into a pre-drilled hole, tightening material by pressure from the tip. We offer specialized options like case-hardened steel and stainless steel (18-8), ensuring consistent performance for both permanent or temporary connections alike.

If your project requires specialty plating or coating, or simply isn't offered in the exact dimensions you need, we would be happy to quote you a custom square head set screw per print.

Select The Best Tip Style For Your Application:

The tip style varies depending on the specific industrial requirements of your application:

• Cup Point: The cup-shaped end aggressively digs into the surface, creating a secure indentation essential for permanent or semi-permanent connections.

• Cone Point: This style is the preferred choice for a permanent application requiring the strongest holding power, as the cone shape efficiently acts like a wedge against the far side of the material.

• Oval Point: Installation causes minimal surface damage, a key feature that allows for easy adjustments without loosening the set screw; it is best suited for installation into a U or V-shaped groove.

• Dog Point: Offers a reliable flat end tip intended to create a stable, permanent connection.

• Flat Point: This tip is often chosen for temporary applications that require frequent setting and resetting of components with the assurance of minimal surface damage.
