Black Alloy Flat Socket Cap with Nylon Pellet (Inch)
Alloy steel flat socket cap screws with a nylon pellet and black finish provide a high‑strength, flush‑mount fastening solution ideal for industrial, mechanical, and OEM applications. Designed with a countersunk flat head and internal hex drive, these screws install flush with the material surface for a clean, smooth profile that reduces interference and enhances safety.
The integrated nylon pellet acts as a positive locking element, generating prevailing torque that prevents loosening caused by vibration, shock, or repetitive movement. Unlike liquid threadlockers, nylon pellets offer reusable performance and consistent locking strength across multiple installation cycles.
The black finish delivers improved wear resistance and a uniform, low‑glare appearance suitable for equipment assemblies, machinery, robotics, electronics housings, and applications where both durability and aesthetics matter.

Manufactured from high‑strength alloy steel, these flat socket cap screws deliver exceptional tensile performance while staying securely in place thanks to the nylon pellet locking feature. The countersunk design ensures a fully flush fit, minimizing the risk of catching, dragging, or obstructing sliding and moving parts.
The black coating provides enhanced surface hardness and moderate corrosion protection, making these screws ideal for indoor industrial environments or controlled‑atmosphere manufacturing setups. Available in a range of diameters and lengths to support precision engineering requirements across OEM, MRO, and assembly operations.
