Alloy Steel Half Dog Point Socket Set Screws

Alloy steel half dog point socket set screws are headless threaded fasteners designed to secure collars, hubs, gears, pulleys, sprockets, knobs, handles, and other components to shafts or mating parts. The internal hex socket allows installation in confined spaces, while the cylindrical half dog point projects beyond the threaded portion to engage a locating hole, groove, or mating recess.

Half dog point geometry is commonly selected where accurate positioning and repeatable component alignment are important. The reduced-diameter locating tip helps position the fastener without relying solely on point pressure against the shaft surface. Depending on the application, the dog point may engage a drilled hole, slot, or machined recess to help maintain alignment while allowing the threaded portion to provide clamping force. Final selection should consider the mating geometry, engagement depth, shaft material, available drive access, and assembly requirements.

These fasteners are frequently used in machinery, indexing mechanisms, tooling, fixtures, collars, hubs, couplings, pulleys, gears, automation equipment, adjustment assemblies, and maintenance applications where repeatable positioning or positive location is required.

Cold Headers supplies alloy steel half 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 exact thread size, screw length, nominal diameter, hex socket size, dog point dimensions, and other verified technical information where available.

Why Use a Half Dog Point Socket Set Screw?

  • Locating tip: The cylindrical half 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 with a hex key where external wrench clearance is limited.
  • Positioning applications: Frequently selected for collars, hubs, couplings, gears, pulleys, fixtures, and indexing mechanisms.
  • Exact-size selection: Product pages allow engineers and purchasers to compare thread size, length, socket size, and verified dimensional information.

Selecting the Correct Half Dog Point Set Screw

Begin by confirming the required thread size and screw length. Review the hex socket size to ensure the proper installation tool is available. Dog point diameter, dog point length, mating-hole dimensions, available drive access, and overall assembly requirements should also be considered. Half dog point set screws should not be substituted automatically for cup, knurled cup, cone, flat, oval, or full 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.
