For any application challenge you have, SKYLOG® custom-engineered solutions are available.
Our team of engineers works with you to design and develop the right fastener for the results you need – whether a modified catalog part or a fully custom solution.

Special Order for Special Fasteners

At SKYLOG, we understand that every project has unique requirements, and off-the-shelf fasteners don’t always meet your exact needs. That’s why we offer special orders—customized fastening solutions tailored to your specifications. Whether you need non-standard sizes, specialty materials, or bulk quantities, SKYLOG’s team is here to help you find the perfect fit for your application.

What are the Benefits of a Custom Part?

Sometimes, standard fasteners and components don’t align with your project’s specific needs. Special orders allow you to:

• Get Custom Sizes & Specifications – Fasteners in unique dimensions, head styles, or thread configurations.

• Select Specialty Materials & Coatings – Options like titanium, Inconel, corrosion-resistant coatings, and electropolishing.

• Meet Industry Regulations – Compliance with AS9100, MIL-SPEC, FDA, RoHS, and REACH requirements.

• Secure Large or Small Batch Orders – Whether you need bulk quantities or low-volume prototypes, we can source the right solution.

Our Special Order Capabilities

Special Order for Screws and Fasteners Surface Finishing

• [Electro Zinc-Plated (Galvanized)]
  • Appearance: Bright, shiny blue-silver.
  • Features: Offers good corrosion resistance for indoor or mild environments.
  • Risk: Can cause hydrogen embrittlement in high-strength (10.9+) fasteners.

• [Stainless Steel (Passivated)]
  • Appearance: Natural, silver sheen.
  • Features: Inherently corrosion-resistant without extra coatings; ideal for wet or harsh environments.

• [Stainless Steel (Silver Plated)]
  • Appearance: White, silver bright.
  • Superior Electrical Conductivity: Silver has the highest electrical conductivity of all metals, making it ideal for electrical connectors and components.
  • Anti-Galling and Lubricity: Silver acts as a dry lubricant, preventing “galling” or seizing of stainless steel screws when tightened, particularly at high temperatures.
  • High-Temperature Resistance: Silver plating can withstand high temperatures, making it suitable for aerospace and engine applications where standard lubricants fail.
  • Corrosion Resistance: It provides good protection against corrosion.
  • Excellent Solderability: It improves the ability to solder the component.

• [Stainless Steel (PTFE)]
  • Appearance: Provides a uniform, smooth, and matte finish.
  • Low Friction & Anti-Galling: Features an ultra-low coefficient of friction (as low as 0.055–0.15). This acts as a dry lubricant, reducing tightening torque, preventing seizing (galling), and ensuring easy removal even after long-term exposure to harsh environments.
  • Superior Corrosion Resistance: Provides excellent protection against salt spray and chemicals, outperforming traditional zinc plating or galvanizing in harsh environments.
  • Non-Stick & Non-Wetting: The surface is hydrophobic and oleophobic, repelling water, oil, and grime, which prevents material buildup on the screw threads.
  • Wide Temperature Range: Stable in extreme temperatures, typically ranging from -190°C to +260°C (-310°F to 500°F).
  • Chemical Inertness: Resistant to oxidation, UV radiation, and most chemicals.
  • Increased Assembly Efficiency: Because it eliminates the need for grease, PTFE coatings are cleaner and do not attract dust or contaminants, reducing maintenance requirements.

• [Stainless Steel (XYLAN)]
  • Appearance: While Xylan 1424 (a common formulation) is typically blue, Xylan coatings are available in a wide variety of colors, allowing for easy identification and organization of parts.
  • Superior Corrosion Resistance: Xylan-coated fasteners can withstand extremely high levels of salt spray, often lasting over 1,500 hours to 10,000 hours, making them ideal for offshore environments.
  • Low Friction (Lubricity): It provides excellent dry-film lubrication, reducing torque required to achieve desired pre-load, and preventing galling and wear during tightening.
  • High Temperature Tolerance: Xylan coatings are thermally stable.
  • Chemical Resistance: It offers high resistance to harsh chemicals, acids, and solvents.
  • Excellent Adhesion: It is designed to adhere strongly to substrates, including carbon steel, stainless steel, and other metals, even under extreme pressure.

• Key Consideration
  • Environment: Outdoor or marine environments require heavy-duty coatings like hot-dip galvanizing or stainless steel.
  • Dimensions: Plating increases thickness, whereas black oxide does not, which is critical for precision screws.
  • Strength: High-strength steels must be treated for hydrogen embrittlement.
  • Corrosion Resistance: Higher resistance usually means higher cost.
