Socket Shoulder Screws, Nylon Pellet, Thermal Black Oxide, Alloy (Inch)
Alloy steel socket shoulder screws with a nylon pellet and thermal black oxide finish deliver a strong, precision‑engineered fastening solution designed for guided movement, pivoting, alignment, and sliding components. Also known as shoulder bolts or stripper bolts, these fasteners feature a precision‑machined shoulder that acts as a bearing surface for mechanical assemblies requiring smooth, consistent motion.
The integrated nylon pellet provides a built‑in locking feature that generates prevailing torque to resist loosening caused by vibration, cyclic movement, or mechanical shock. This locking mechanism eliminates the need for external adhesives while still allowing for repeated adjustments and removals. The thermal black oxide coating enhances wear resistance, improves lubricity during installation, and gives the fastener a clean, uniform, low‑glare black finish.

Nylon‑pellet socket shoulder screws are ideal for high‑precision equipment such as automation systems, robotics, material‑handling mechanisms, linkages, molds, dies, jigs, and motion‑control assemblies. The smooth shoulder ensures reliable linear or rotational movement, while the alloy steel core delivers high tensile strength and durability under load.
The nylon pellet locking element provides consistent retention torque, making these screws an excellent choice for applications exposed to vibration or continuous duty cycles. The thermal black oxide finish adds mild oxidation resistance and improved handling during assembly, making these fasteners well‑suited for industrial and OEM environments.
Available in a wide selection of shoulder diameters, lengths, and thread sizes to meet custom engineering and production requirements.
