Cup Point 18-8 Stainless Steel Metric Socket Set Screws

Cup point 18-8 stainless steel metric socket set screws are headless threaded fasteners designed to secure collars, hubs, gears, pulleys, couplings, sprockets, knobs, handles, and other shaft-mounted components in metric mechanical assemblies. The internal hex drive allows installation where external wrench clearance is limited, while the recessed cup point creates localized rim contact with the mating surface to help secure assembled components. Their compact design allows installation flush with or below the surrounding surface.

Manufactured from 18-8 stainless steel, these metric socket set screws provide general corrosion resistance for many industrial environments exposed to moisture, humidity, or routine washdown. They are commonly specified for metric machinery, automation equipment, robotics, instrumentation, conveyors, machine tools, maintenance repairs, and OEM manufacturing where stainless steel construction and metric fastening are required.

Cup point geometry is frequently selected where concentrated contact with the mating surface is desired. Depending on the shaft material and installation conditions, the point may leave a witness mark or shallow indentation on the contacted surface. Proper fastener selection should consider metric thread size, screw length, metric hex socket size, mating material, installation access, acceptable surface marking, and service conditions. Individual product pages provide verified engineering dimensions to assist engineers and purchasing professionals in selecting the appropriate fastener.

Cold Headers supplies cup point 18-8 stainless steel metric socket set screws in a broad range of metric thread sizes and lengths, including standard, 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 Cup Point 18-8 Stainless Steel Metric Socket Set Screws?

  • Cup point geometry: Creates localized rim contact with the mating surface.
  • Metric thread sizes: Designed for machinery and equipment utilizing metric fasteners.
  • Internal hex drive: Allows installation using standard metric hex keys or hex bits.
  • 18-8 stainless steel: Provides general corrosion resistance for many industrial environments.
  • Verified engineering dimensions: Product pages provide metric thread size, screw length, nominal diameter, metric hex socket size, and additional engineering information where available.

Selecting the Correct Metric Cup Point Socket Set Screw

Begin by confirming the required metric thread size and screw length. Review the metric hex socket size, mating material, installation clearance, operating environment, acceptable surface marking, and assembly requirements before selecting a fastener. Cup point socket set screws should not be substituted automatically for cone point, flat point, oval point, knurled cup point, half dog point, or full dog point designs 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 professionals, and purchasing teams locate exact metric sizes, uncommon lengths, and difficult-to-find metric socket set screws without unsupported inventory claims.
