Full Dog Point Alloy Steel Socket Set Screws

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

Unlike point styles that rely primarily on contact with the shaft surface, full dog point set screws are commonly selected where the locating feature of the extended dog point is an integral part of the assembly. The cylindrical projection helps position mating components while the threaded section secures the assembly. These fasteners are frequently used in machinery, indexing mechanisms, automation equipment, tooling, fixtures, couplings, conveyor systems, power transmission equipment, maintenance repairs, and OEM manufacturing where accurate positioning is essential.

Manufactured from alloy steel, these socket set screws are intended for demanding industrial mechanical applications. Proper fastener selection should consider thread size, screw length, dog point diameter, dog point length, mating-hole dimensions, installation access, and assembly requirements. Individual product pages provide verified engineering dimensions to assist engineers and purchasing professionals in selecting the appropriate fastener.

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

Why Choose Full Dog Point Socket Set Screws?

  • Extended cylindrical dog point: Designed to engage a mating hole, groove, or recess for repeatable positioning.
  • Headless construction: Installs flush with or below the surrounding component surface.
  • Internal hex drive: Allows installation using standard hex keys where external wrench clearance is limited.
  • Alloy steel construction: Intended for demanding industrial mechanical applications.
  • Verified engineering dimensions: Product pages provide thread size, screw length, dog point dimensions, and hex socket size 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, installation clearance, and assembly requirements before selecting a fastener. Full dog point set screws should not be substituted automatically for cup point, knurled cup point, cone point, flat point, oval point, 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 alloy steel socket set screws without unsupported inventory claims.
