Socket Set Screws: Standard & Metric Point Styles

Unlike standard screws that feature a head and threaded shaft, headless socket set screws consist of a fully threaded shaft designed for flush installation. These fasteners utilize an internal hex drive (hex socket) on one end, allowing for easy adjustment with a standard hex key or Allen wrench. This design is ideal for mechanical assemblies with tight space constraints, such as securing a pulley or gear to a shaft, as the screw sits flush or just below the surface once the appropriate torque is applied. Whether your project requires a cup point set screw for permanent grip or a flat point for frequent adjustments, our selection includes multiple thread size options and finishes like black oxide for added protection.

Set screws are a highly cost-effective fastener choice, reducing the need for secondary components like nuts. If you need a specialized solution such as nylon patch or pellet options to prevent loosening from vibration, our knowledgeable sales team is ready to assist.

Guide to Socket Set Screw Point Styles & Applications:

• Cup Point: the cup shaped end digs into the surface for permanent and semi-permanent connections 
• Cone Point: often the preferred choice for a permanent application that requires the strongest holding power as the cone shape acts like a wedge against the far side of the material
• Oval Point: installation causes very little damage to allow adjustments without loosening the screw; best suited for installation into a U or V shaped groove 
• Dog Point: offer a flat end tip in full or half length, intended to offer a permanent connection
• Flat Point: often the preferred choice for temporary applications that require setting and resetting with minimal surface damage 
• Slotted: installation can be accomplished with a flat screwdriver instead of a hexagon shaped tool as the other set screw options
• Knurl Cup: serrated ridges (knurls) on the cup shaped end allow the screw to lock in place for a permanent connection; reduces loosening caused by environmental factors such as vibrations
• Brass Tip: the tip will be inserted and aligned with a hole/slot in the material, creating a permanent connection that offers a higher level of corrosion resistance if the far side of the connection is in a wet environment
• Nylon Tip: othe tip will be inserted and aligned with a hole/slot in the material, creating a permanent connection that offers a higher level of chemical resistance with nonconductive properties
