Square Head Set Screws (1/2 Dog, Full Dog, Flat Point, Cone Point & Oval Point)

Square head set screws are externally driven threaded fasteners designed to secure collars, pulleys, gears, couplings, hubs, levers, adjustment mechanisms, and other shaft-mounted components. The square head provides wrench engagement for installation and removal, while a variety of point styles allows the fastener to be selected for specific holding and positioning requirements across industrial mechanical assemblies.

Cold Headers supplies square head set screws in multiple point configurations, including 1/2 dog point, full dog point, flat point, cone point, and oval point styles. Each point geometry is intended for a different mechanical function, allowing engineers and maintenance professionals to select the appropriate fastener for positioning, adjustment, or shaft engagement requirements.

Manufactured for demanding industrial applications, square head set screws are commonly specified for machinery, power transmission equipment, agricultural equipment, industrial maintenance, conveyors, machine tools, pumps, valves, adjustment mechanisms, tooling, and OEM manufacturing.

Proper fastener selection should consider thread size, screw length, point style, wrench accessibility, mating material, installation clearance, and service conditions. Individual product pages provide verified engineering dimensions to assist engineers and purchasing professionals in selecting the appropriate square head set screw.

Cold Headers supplies square head set screws in a broad range of inch thread sizes and lengths, including standard, uncommon, and difficult-to-source configurations. Our catalog is organized to simplify exact-size sourcing while providing consistent engineering information across every product family.

Available Point Styles

• 1/2 Dog Point: Short locating projection commonly used where positioning within a mating hole or slot is required.
• Full Dog Point: Extended locating projection for applications requiring positive engagement within a mating hole.
• Flat Point: Broad bearing surface commonly selected where reduced surface marking is preferred.
• Cone Point: Concentrated point contact commonly selected where positive holding action is desired.
• Oval Point: Rounded bearing surface commonly selected where repeated adjustment or repositioning is anticipated.

Selecting the Correct Square Head Set Screw

Begin by confirming the required thread size and screw length. Review the required point style, mating material, installation clearance, and operating environment before selecting a fastener. The selected point geometry should reflect the mechanical requirements of the completed assembly, as each point style serves a different functional purpose.
