18-8 Stainless Steel Socket Set Screws

18-8 stainless steel socket set screws are headless threaded fasteners designed to secure collars, hubs, gears, pulleys, knobs, handles, bearings, couplings, and other shaft-mounted components. Their internal hex drive allows installation where external wrench clearance is limited, while the absence of a protruding head permits installation flush with or below the surrounding surface.

Cold Headers supplies multiple 18-8 stainless steel socket set screw point styles to accommodate different holding, positioning, and assembly requirements. Available configurations include Flat Point, Oval Point, Cone Point, and Half Dog Point designs. Each point geometry creates a different contact condition with the mating component, allowing engineers to select the style best suited for positioning, alignment, reduced surface marking, or engagement with a machined recess.

18-8 stainless steel is commonly selected for applications requiring general corrosion resistance in environments exposed to moisture, humidity, or routine washdown. These socket set screws are widely used in industrial machinery, automation equipment, packaging systems, conveyor assemblies, instrumentation, pumps, electric motors, power transmission equipment, fixtures, maintenance repairs, and OEM manufacturing.

Individual product pages provide verified dimensional information including thread size, nominal diameter, screw length, hex socket size, and applicable point geometry where available. Cold Headers offers both standard and difficult-to-source inch sizes to help engineers and purchasing professionals specify the correct fastener for demanding applications.

Available Point Styles

  • Flat Point: Broad contact surface commonly selected where reduced surface marking and repeated adjustment are preferred.
  • Oval Point: Rounded contact surface suited for applications requiring smooth contact with the mating component.
  • Cone Point: Tapered point used where concentrated contact or engagement with a locating recess is desired.
  • Half Dog Point: Cylindrical locating tip designed to engage a mating hole, groove, or recess for repeatable positioning.

Why Choose 18-8 Stainless Steel Socket Set Screws?

  • Internal hex drive for installation in confined spaces.
  • Headless design allows flush or below-surface installation.
  • 18-8 stainless steel construction provides general corrosion resistance for many industrial environments.
  • Multiple point styles support a wide range of holding and positioning requirements.
  • Verified engineering dimensions help simplify specification and procurement.
