18-8 Stainless Steel Full Dog Point Socket Set Screws

18-8 stainless steel full dog point socket set screws are headless threaded fasteners designed to positively locate and secure collars, hubs, gears, pulleys, couplings, knobs, handles, and other shaft-mounted components. The internal hex socket allows installation in confined spaces, while the extended cylindrical full dog point projects beyond the threaded portion to engage a mating hole, slot, or machined recess for repeatable positioning.

Unlike point styles that rely primarily on surface contact, full dog point set screws are commonly selected where the locating feature of the dog point is an important part of the assembly design. The extended cylindrical tip helps maintain alignment between mating components while the threaded portion secures the assembly. Proper selection should consider dog point diameter, dog point length, mating-hole dimensions, shaft material, available drive access, and overall assembly requirements.

18-8 stainless steel provides general corrosion resistance for many industrial environments exposed to ordinary moisture, humidity, or routine washdown. These fasteners are widely used in automation equipment, machinery, indexing mechanisms, fixtures, tooling, conveyor systems, power transmission equipment, instrumentation, maintenance repairs, and OEM assemblies requiring accurate positioning and repeatable alignment.

Cold Headers supplies 18-8 stainless steel full dog point socket set screws in a broad range of inch thread sizes and lengths, including uncommon and difficult-to-source configurations. Individual product pages provide verified thread size, screw length, nominal diameter, hex socket size, dog point dimensions, and other engineering information where available.

Why Use a Full Dog Point Socket Set Screw?

  • Extended locating point: The cylindrical full dog point is designed to engage a mating hole, groove, or recess for repeatable positioning.
  • Headless construction: Allows installation flush with or below the surrounding component surface.
  • Internal hex drive: Supports installation where external wrench clearance is limited.
  • 18-8 stainless steel: Provides general corrosion resistance for many industrial environments.
  • Exact-size selection: Product pages provide verified thread size, length, socket size, and dog point dimensions where available.

Selecting the Correct Full Dog Point Set Screw

Begin by confirming the required thread size and screw length. Review the dog point diameter, dog point length, mating-hole dimensions, available installation access, and assembly requirements before selecting a fastener. Full dog point set screws should not be substituted automatically for cup, knurled cup, cone, flat, oval, or half dog point styles because each point geometry serves a different mechanical function.

Cold Headers Inc. has supplied specialty industrial socket fasteners since 1962. Our catalog helps engineers, distributors, maintenance teams, and purchasing professionals locate exact sizes, uncommon lengths, and difficult-to-find stainless steel socket set screws without unsupported inventory claims.

Description N/A

4-40 x 1/8 Full Dog Point 18-8 Stainless Steel Socket Set Screw uses a cylindrical unthreaded pilot tip to locate into a drilled hole, slot, or groove. The pilot end locates the part rather than biting or indenting the mating surface.

Common application reviews include travel stops and limit stops on slides and lead screws. The full dog point does not rely on biting action; it seats into the prepared mating feature and helps hold position through mechanical location.

18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material referenced to ASTM F880 for general plant environments, moisture exposure, and clean appearance. Cold Headers has supplied specialty socket fasteners since 1962 and supports exact-size sourcing for hard-to-find socket products.

For drawings calling out 4-40 x 3/16, this full dog point 18-8 stainless socket set screw provides threaded adjustment with a pilot-style locating end. The pilot end locates the part rather than biting or indenting the mating surface.

Common application reviews include pivot points, detent positions, and locating-pin style assemblies. Compared with a half dog point, the full dog style provides a longer cylindrical tip for deeper prepared holes or slots.

18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material referenced to ASTM F880 for general plant environments, moisture exposure, and clean appearance. Cold Headers helps buyers match uncommon stainless socket set screw sizes to existing drawings and maintenance records.

 		N/A

Use the 4-40 x 5/16 full dog point 18-8 stainless socket set screw when a component must seat in a prepared hole or milled slot. The pilot end locates the part rather than biting or indenting the mating surface.

Common application reviews include positioning parts that must be removable without shaft damage. Compared with a flat point, the full dog point is used when the assembly needs pilot-tip engagement rather than broad bearing on a finished surface.

18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material referenced to ASTM F880 for general plant environments, moisture exposure, and clean appearance. Cold Headers' socket-fastener focus is useful when thread, length, material, and point style must line up precisely.

 		N/A

The 4-40 x 3/8 full dog point socket set screw in 18-8 stainless is built around a concentric cylindrical tip that works like a threaded locating pin. The pilot end locates the part rather than biting or indenting the mating surface.

Common application reviews include hanger screws, adjustment screws, and equipment setting points. Review the hole depth, slot width, mating material, and wrench access before replacing another point style with a full dog configuration.
