DIN 427 Slotted Headless Screw with Chamfered End – A1 (AISI 303) 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 installation and adjustment using a standard flat-blade screwdriver, making these screws practical for precise positioning and fastening tasks.
Material
Manufactured from A1 (AISI 303) stainless steel, these screws provide good mechanical strength together with reliable corrosion resistance. AISI 303 stainless steel is well known for its excellent machinability and consistent dimensional accuracy while still offering resistance to rust in humid or mildly corrosive environments. The natural stainless finish maintains a clean, professional appearance while preserving the material’s inherent durability and resistance to oxidation.
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 machine building, tooling, industrial equipment, and maintenance applications where components must be held firmly in place without a protruding fastener head. Their compact design makes them especially suitable for tight spaces, adjustment points, and assemblies requiring precise alignment and reliable locking performance.
