S-97188A415 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor sheet metal applications.
• Superior torque transmission and reduced cam-out thanks to the square drive design, ensuring reliable and efficient installation.
• Strong, permanent threads are created by the thread-forming (A/AB) tapping method, eliminating the need for a pre-tapped hole and providing excellent holding power in sheet metal.
• Optimized for 0.025" maximum sheet thickness when used with the recommended No. 21 drill bit, ensuring precise and secure fastening in thin materials.
• Fully threaded shank provides maximum grip and clamping force along the entire length of the screw for a more secure assembly.
• Wide-bearing pan head distributes clamping force effectively, helping to prevent pull-through and damage to the sheet metal surface.
• Compliant with major environmental regulations including RoHS 3 and REACH, making them suitable for global supply chains and sensitive industrial applications.

Professional Applications & Engineering Value

These 316 stainless steel tapping screws are engineered to solve common fastening challenges in sheet metal fabrication and assembly. The thread-forming design cold-forms a mating thread in the base material, creating a tight, vibration-resistant fit that is stronger than using pre-tapped holes. This is critical in sheet metal applications where material thickness is limited, and thread stripping is a major concern. The combination of a square drive and a pan head provides a low-profile, high-torque solution that resists cam-out during installation, speeding up production lines and reducing tool wear. The superior corrosion resistance of 316 stainless steel ensures long-term reliability and structural integrity, even when exposed to moisture, chemicals, or salt-laden atmospheres, making these screws a robust choice for HVAC, automotive, and marine industries.
