Thermal Baked Black Oxide with Nylon Patch Cone Point Socket Set Screws

Baked black oxide with nylon patch cone point socket set screws are precision-engineered fasteners designed for high-strength, vibration-resistant applications where a sharp, penetrating hold is essential. These specialized screws are ideal for mechanical assemblies, power transmission systems, toolmaking, and rotating equipment where secure axial or radial locking is required.

The cone point features a sharp, tapered tip that delivers focused pressure, ideal for penetrating and locking into a mating surface. This design provides maximum holding power and is commonly used in permanent installations or where alignment of parts—such as gears, collars, and shafts—is crucial.

The baked black oxide finish enhances corrosion resistance and adds a sleek, low-glare appearance while improving lubricity for smoother torque application. It also helps prevent galling and seizing during installation, making it perfect for high-precision environments.

A key feature is the pre-applied nylon patch, which acts as a locking element to resist vibration-induced loosening. Unlike traditional thread-locking compounds, the nylon patch offers reusable, friction-based security without the mess. It conforms to threads during installation, providing added resistance to loosening while allowing for adjustability.

Specifications include:

• Point Type: Cone point

• Drive Type: Internal hex (socket)

• Material: Hardened alloy steel

• Finish: Baked black oxide

• Locking Feature: Nylon patch (pre-applied)

• Standards: ASME B18.3

• Sizes: Typically from #4-40 to 1/2-13 and metric equivalents

Whether you’re securing critical rotating components or need a tamper-resistant set screw for high-vibration environments, baked black oxide cone point screws with nylon patches provide strength, reliability, and precision.
