S-97503A158 Length 45 mm DIN 7983, ISO 7051 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Efficient, self-tapping installation through thread cutting design, reducing labor time and eliminating the need for pre-tapped holes in metal and sheet metal.
• Secure, flush-mount finish with a standard oval head and 80° countersink angle for a smooth, professional appearance and reduced snagging.
• Reliable, non-slip driving provided by the Phillips No. 2 drive, ensuring consistent torque application and minimizing cam-out during installation.
• Maximum grip and holding power from the fully threaded, pointed tip design, which ensures strong engagement along the entire 45mm length.
• Guaranteed dimensional precision and interchangeability, manufactured to meet DIN 7983 and ISO 7051 standards for reliable performance.
• Safe for regulated industries, fully compliant with RoHS 3 and REACH environmental directives, ensuring no hazardous substances.

Professional Applications & Engineering Value

These M4.8 x 45mm tapping screws are precision-engineered to solve common fastening challenges in metal and sheet metal assemblies. The 18-8 stainless steel material offers excellent resistance to oxidation and corrosion, making these screws suitable for outdoor, marine, or chemically exposed settings. The thread cutting (Type C) tapping method allows the screw to form its own mating thread as it's driven, which is critical for reducing assembly steps and preventing strip-out in thin materials. Combined with the Phillips drive and oval head, this design ensures quick, secure installations with a finished look, minimizing the risk of work piece damage and improving overall structural integrity in HVAC, automotive, and machinery applications.
