S-97503A175 Length 25 mm DIN 7983, ISO 7051 Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel construction ensures long-term reliability in harsh industrial environments, reducing replacement costs and maintenance downtime.
• Self-tapping thread-cutting design (Type C) eliminates the need for pre-tapped holes, speeding up assembly in metal and sheet metal applications.
• Phillips drive with No. 3 size provides secure, efficient torque transfer and reduces the risk of cam-out during installation.
• Oval head with standard profile offers a finished, flush appearance when seated, enhancing both aesthetics and safety by minimizing snagging.
• Full threading and pointed tip ensure quick, deep penetration and strong holding power in a variety of material thicknesses.
• Compliance with DIN 7983/ISO 7051 standards guarantees dimensional accuracy and interchangeability, supporting global engineering specifications.
• RoHS 3 and REACH compliance confirms environmental safety and regulatory adherence for use in sensitive or export-focused industries.

Professional Applications & Engineering Value

Engineered for demanding metal and sheet metal applications, these M6.3 metric tapping screws deliver exceptional value by solving common assembly challenges. The 18-8 stainless steel material resists oxidation and chemical exposure, making it ideal for outdoor, marine, or high-moisture settings. With a thread-cutting (Type C) design and pointed tip, the screw forms precise internal threads as it drives, eliminating costly pre-tapping operations and reducing labor time. The Phillips oval head combines easy drive engagement with a low-profile finish, preventing surface damage and ensuring a secure fit in countersunk holes. This combination of durability, efficiency, and standardized dimensions (DIN 7983/ISO 7051) makes these screws a reliable choice for HVAC, automotive, and machinery assembly, where vibration resistance and long-term performance are critical.

Specification Summary & Compliance

This M6.3 x 25mm tapping screw features a 0.25" thread diameter and is fully threaded for consistent grip. It adheres to DIN 7983 and ISO 7051 specifications, ensuring precise thread form and dimensional tolerances. The screw is manufactured with an 80° countersink angle and standard oval head profile for proper seating. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms it is free of restricted substances, meeting international environmental and safety standards for industrial use.
