Nylon and Brass Tip 18-8 Stainless Steel Socket Set Screws

Nylon tip and brass tip 18-8 stainless steel socket set screws are headless threaded fasteners designed for applications where contact with the mating surface benefits from a softer tip material than steel. The internal hex drive allows installation where external wrench clearance is limited, while the replaceable nylon or brass tip provides a bearing surface intended for applications requiring repeated adjustment, positioning, or contact with finished components. These fasteners install flush with or below the surrounding surface for a clean, compact assembly.

Manufactured with an 18-8 stainless steel body, these socket set screws provide general corrosion resistance for many industrial environments exposed to moisture, humidity, or routine washdown. Nylon tip and brass tip designs are commonly selected for collars, hubs, pulleys, shafts, adjustment mechanisms, guides, instrumentation, machine components, automation equipment, fixtures, maintenance repairs, and OEM manufacturing where a softer contact surface is preferred over hardened steel.

Proper fastener selection should consider thread size, screw length, hex socket size, tip material, mating material, installation access, and service environment. Individual product pages provide verified engineering dimensions, including thread size, screw length, nominal diameter, hex socket size, and additional engineering information where available to assist engineers and purchasing professionals in selecting the appropriate fastener.

Cold Headers supplies nylon tip and brass tip 18-8 stainless steel socket set screws in a broad range of inch 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 Nylon and Brass Tip 18-8 Stainless Steel Socket Set Screws?

  • Nylon and brass tip options: Designed for applications requiring a softer point of contact than steel.
  • Internal hex drive: Allows installation using standard hex keys where external wrench clearance is limited.
  • 18-8 stainless steel body: Provides general corrosion resistance for many industrial environments.
  • Broad industrial applications: Commonly used on collars, shafts, adjustment mechanisms, instrumentation, fixtures, automation equipment, and OEM assemblies.
  • Verified engineering dimensions: Product pages provide thread size, screw length, nominal diameter, hex socket size, and additional engineering information where available.

Selecting the Correct Nylon or Brass Tip Socket Set Screw

Begin by confirming the required thread size and screw length. Review the desired tip material, mating component, installation clearance, operating environment, and assembly requirements before selecting a fastener. Final selection should reflect the functional requirements of the completed assembly.

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

Description N/A

4-40 x 1/8 Nylon Tip 18-8 Stainless Steel Socket Set Screw uses a nylon tip on an 18-8 stainless steel socket set screw body for controlled contact on finished parts. The nylon face is the softer option for delicate finishes or frequently reset contact points.

Used around polished shaft collars, knobs, and small hubs, it bears on finished surfaces with controlled contact. Internal socket access keeps the screw headless for compact adjustment points.

Cold Headers has supported specialty socket fasteners since 1962 and helps match exact thread, length, and tip details. Check the 4-40 x 1/8 thread, threaded length, tip length, tip diameter, mating material, and drive access against the drawing. The 3A thread fit is retained after tip installation for precision socket set-screw engagement.

4-40 x 3/16 Nylon Tip 18-8 Stainless Steel Socket Set Screw is built for set-screw holding where a nylon contact face is preferred over a bare point. A nylon contact face helps treat the part under the screw more gently during adjustment.

Spline shafts, keyed shafts, and positioning components use the tip as a sacrificial contact face. Internal socket access keeps the screw headless for compact adjustment points.

Cold Headers focuses on specialty socket fasteners where drawings require a specific tip material and length. Check the 4-40 x 3/16 thread, threaded length, tip length, tip diameter, mating material, and drive access against the drawing. Cold Headers installs nylon tips at its Chicago facility for non-catalog set-screw and cap-screw work. The A and C tip dimensions give 4-40 x 3/16 a row-specific contact profile for purchasing review.

4-40 x 1/4 Nylon Tip 18-8 Stainless Steel Socket Set Screw gives designers a soft-contact socket set screw option with a nylon tip and 18-8 stainless steel body. Nylon is specified when the application needs a softer sacrificial tip instead of direct stainless contact.

Electrical enclosure hardware and control-panel mechanisms use the headless form where covers need clearance. Internal socket access keeps the screw headless for compact adjustment points.

For maintenance, production, and distributor sourcing, Cold Headers can help verify size and tip data. Check the 4-40 x 1/4 thread, threaded length, tip length, tip diameter, mating material, and drive access against the drawing. 18-8 Set Screws with Nylon Insert grip the tapped hole; this tip screw protects the contacted surface. The A and C tip dimensions give 4-40 x 1/4 a row-specific contact profile for purchasing review.

4-40 x 5/16 Nylon Tip 18-8 Stainless Steel Socket Set Screw is a tip-style 18-8 stainless socket set screw for assemblies where surface condition matters. For light contact on finished components, the nylon tip shifts wear toward the replaceable screw end.

Lead screws, ball screws, and rack adjustments use this style where a bare point would be too aggressive. Internal socket access keeps the screw headless for compact adjustment points.

Check the 4-40 x 5/16 thread, threaded length, tip length, tip diameter, mating material, and drive access against the drawing. Because the tip is added to the working end, the 3A thread fit remains available for close-fitting tapped holes. With stainless collars, moderate drive speed and suitable anti-seize can help reduce galling.
