Alloy Thermal Black Oxide Flat Socket Cap with Nylon Patch (Inch)
Alloy steel flat socket cap screws with a nylon patch and thermal black oxide finish provide a high‑strength, flush‑mount fastening solution with built‑in vibration resistance. Designed with a countersunk flat head and internal hex drive, these screws sit flush with the material surface for a clean, low‑profile installation ideal for machinery, enclosures, automation equipment, and other tight‑clearance assemblies.
The nylon patch acts as a pre‑applied locking element, supplying prevailing torque that resists loosening caused by vibration, shock, or repetitive motion. This eliminates the need for liquid threadlockers while allowing for multiple reuses without degrading performance.
The thermal black oxide coating enhances wear resistance, reduces friction, and provides moderate corrosion protection—while giving the screw a uniform, non‑reflective black finish suitable for industrial and OEM environments.

Engineered from durable alloy steel, these flat socket cap screws deliver excellent tensile strength and long‑term reliability. The flush‑mount countersunk head prevents interference with moving or sliding components, making them ideal for applications where protrusion must be minimized for safety or operational clearance.
The integrated nylon locking patch offers consistent torque retention, making these screws a dependable choice for assemblies exposed to vibration or continuous operation. The thermal black oxide finish provides added surface protection and enhances lubricity for easier installation.
Available in multiple diameters and lengths to meet precise industrial, mechanical, and manufacturing requirements
