DIN 427 Slotted Headless Screw with Chamfered End – A4-50 Stainless Steel
DIN 427 screws are slotted headless set screws designed for secure positioning and locking of components within mechanical assemblies. The headless design allows the screw to sit fully within the threaded hole, while the chamfered end helps guide the screw into place and provides smooth contact with the mating surface. The slotted drive enables straightforward installation and adjustment using a standard flat-blade screwdriver, making these screws suitable for precise positioning and fastening applications.
Material
Manufactured from A4-50 stainless steel, these screws offer excellent corrosion resistance along with dependable mechanical strength. A4 stainless steel (commonly equivalent to 316 grade) provides enhanced resistance to moisture, salt, and chemical exposure compared to standard stainless materials. The natural stainless finish maintains a clean appearance while ensuring long-term durability in demanding environments, including outdoor and marine salt water conditions.
Use
DIN 427 slotted headless screws are commonly used for securing shafts, locking collars, positioning components, and fixing parts within machinery and mechanical equipment. They are widely found in marine equipment, food processing machinery, chemical processing systems, and industrial assemblies where corrosion resistance is critical. Their compact headless design makes them especially suitable for tight installation spaces, adjustment points, and assemblies requiring reliable locking without a protruding fastener head.
