We supply high-quality 304 stainless steel hex socket cylindrical point set screws, also named headless hex grub screws and locking stop screws, covering complete specifications M3, M4, M5, M6 and M8. Made of genuine 304 stainless steel, these set screws deliver outstanding rust resistance, corrosion resistance and stable mechanical performance, perfectly adapting to humid, corrosive and indoor precision working environments. Adopting hex socket drive and cylindrical pointed end design, these headless set screws enable tool-free convenient installation, precise positioning and strong anti-loosening locking. The pointed end can closely fit workpiece grooves and holes for effective limiting and fixing, while the headless flush structure keeps the assembly surface flat without protrusion. With standard thread pitch and precise machining tolerance, the screws fit smoothly and lock firmly without slipping. Widely used in precision machinery, mold fixtures, electronic equipment, instrumentation, automation parts and hardware assembly industries, they are ideal for positioning, limiting and anti-loosening fastening. We have sufficient stock of all standard sizes, support bulk wholesale and long-term stable supply, providing reliable professional fastening solutions for industrial precision assembly and mechanical locking applications.
