Socket Set Screw with Dog point (DIN915)

Socket Set Screw with Dog Point (DIN915), also known as Dog Point Socket Set Screw, Dog Point Grub Screw, Allen Set Screw, Hex Socket Set Screw with Dog Point or Dog Point Headless Screw, is a headless threaded fastener with an internal hexagon socket drive and a cylindrical dog point at the end. It is commonly used to lock, locate, guide or position one component against another without using a traditional screw head.

Unlike a cup point or cone point set screw that bites directly into the mating surface, a dog point set screw has a short cylindrical projection at the tip. This dog point can enter a drilled hole, slot, groove or locating recess in the mating part, helping to provide positive positioning and repeatable location in selected mechanical assemblies.

Socket Set Screw with Dog Point (DIN915) is commonly used in machinery, shafts, collars, pulleys, gears, sprockets, couplings, hubs, knobs, handles, jigs, fixtures, guide mechanisms, sliding parts, automation equipment, motors, pumps, gearboxes and industrial maintenance applications. It is suitable where accurate location, repeatable positioning or reduced surface damage is required.

Why Choose Our Socket Set Screw with Dog Point (DIN915)

Choosing the correct Socket Set Screw with Dog Point (DIN915) is important for location accuracy, thread fitment, point engagement, corrosion resistance, drive engagement and long-term assembly reliability. The screw should match the thread size, thread pitch, length, material, finishing, hex socket size, mating threaded hole, dog point diameter, locating hole, shaft material, tightening torque and working environment.

Steel Socket Set Screw with Dog Point with Black Oxide Finishing is a practical option for general machinery, indoor equipment, pulleys, collars, gears, sprockets, couplings, knobs, handles, jigs, fixtures, automation equipment and industrial maintenance applications. Stainless Steel 304 (A2) Socket Set Screw with Dog Point is suitable when better corrosion resistance, cleaner appearance and stainless steel material compatibility are required.

The dog point design is useful when the application needs positive location instead of only friction-based holding. The cylindrical point can enter a prepared hole, slot or groove, helping the part return to the same position during assembly or maintenance. This makes it useful for positioning collars, locating hubs, guiding sliding parts and securing components that may need repeatable alignment.

Compared with cup point or cone point set screws, dog point set screws are less aggressive when used with a properly prepared locating hole. Cup point and cone point styles usually bite into the shaft surface, while dog point style can engage into a hole or slot for a more controlled mechanical location. However, the mating component should be designed with the correct hole, slot or groove for best performance.

DIN915 / ISO 4028 set screws are commonly used for replacement and maintenance because many machines and mechanical parts require the correct point style. Users should confirm whether the existing screw is dog point, cup point, cone point or flat point before ordering, because each point style performs differently.

For best performance, the screw should be tightened using the correct Allen key size and suitable torque. For high-speed rotating, high-load, safety-related, vibration-prone or critical machinery assemblies, screw size, thread engagement, dog point engagement, shaft hardness, torque value and joint design should be checked by a qualified person or project specification.
