Professional industrial grade setting screws, precision-engineered to meet DIN916 and GB80 standards, exclusively designed for mechanical equipment fastening, positioning, and anti-loosening applications. Crafted from premium 304 and 316 stainless steel, these headless concave end setting screws (also known as machine rice, top wire, or stop payment nails) deliver exceptional corrosion resistance, rust proofing, and structural durability—ideal for use in industrial machinery, electronic equipment, precision instruments, and mechanical assemblies that require tight, secure positioning.
Our M1.6-16 setting screws feature a headless concave end design, allowing for flush installation that won’t protrude or interfere with mechanical movement, ensuring seamless operation of your equipment. The precision-machined threads (compliant with DIN916/GB80 standards) provide a tight, anti-loosening fit, preventing slippage even under continuous mechanical vibration, high pressure, or harsh industrial environments. 304 stainless steel offers reliable general corrosion resistance for dry/wet working conditions, while 316 stainless steel provides enhanced acid, alkali, and high-humidity resistance—perfect for harsh industrial settings, marine applications, or food-grade equipment.
Designed as multi-purpose industrial fasteners, these top wire stop nails are widely used for locking shafts, gears, pulleys, bearings, and other mechanical components, delivering precise positioning and secure fastening without damaging the connected parts. The headless design saves space, making them ideal for compact mechanical assemblies, electronic devices, and precision instruments where clearance is limited.
Easy to install with standard tools, these setting screws require no special equipment, ensuring efficient assembly and maintenance. Whether you’re replacing worn fasteners, repairing industrial machinery, or assembling new equipment, our DIN916 GB80 setting screws meet strict industrial precision standards, offering consistent performance and long service life—eliminating frequent replacements and reducing maintenance downtime.
