S-97503A177 Length 38 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 long-term reliability.
• Efficient thread cutting action (Type C) creates precise mating threads in metal and sheet metal, reducing installation time and effort.
• Secure and flush installation with a standard oval head and 80° countersink angle for a smooth, professional finish that minimizes snagging.
• Enhanced torque transmission provided by the Phillips No. 3 drive, preventing cam-out and ensuring a tight, reliable fastening.
• Full-length threading (M6.3 x 38mm) offers maximum grip and holding power along the entire shank for superior load distribution.
• Guaranteed dimensional accuracy and interchangeability, manufactured to meet the stringent DIN 7983 / ISO 7051 standards.
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

These M6.3 tapping screws are precision-engineered from 18-8 stainless steel to solve common fastening challenges in metal and sheet metal assemblies. The thread cutting design eliminates the need for pre-tapped holes, significantly speeding up production while providing strong, reliable threads in ductile materials. The oval head with Phillips drive ensures a countersunk, low-profile finish that is both aesthetically pleasing and functional, reducing the risk of corrosion traps and improving worker safety. This combination of material durability and efficient self-tapping performance makes them an essential component for HVAC systems, electronic enclosures, and automotive panels where vibration resistance and a secure hold are critical.
