S-95641A151 Length 3/4" 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.
• Enhanced tamper-resistant security through the Tri-Wing® drive, reducing unauthorized access in sensitive applications.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, saving assembly time and labor costs.
• Optimized for 0.025" maximum thickness materials with a pointed tip and compatibility with No. 32 drill bits, ensuring precise, clean installations.
• High thread engagement with 18 TPI and full threading along the 3/4" length, providing excellent pull-out strength and vibration resistance.
• Broad compliance assurance meeting RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.
• Versatile pan head design with a rounded profile for a low-profile finish and even load distribution in sheet metal assemblies.

Professional Applications & Engineering Value

These No. 6 x 3/4" Tri-Wing® tapping screws are engineered to address common challenges in sheet metal fastening, such as material fatigue and corrosion. Made from 18-8 stainless steel, they offer excellent resistance to rust and oxidation, making them suitable for outdoor, automotive, and HVAC systems. The thread forming technology eliminates the need for separate tapping operations, reducing assembly steps and minimizing the risk of cross-threading. With a pointed tip and precise 0.138" thread diameter, these screws ensure quick starts and secure holds in thin-gauge metals up to 0.025" thick, enhancing productivity in high-volume manufacturing. Their right-hand threading and fully threaded design provide consistent clamping force, ideal for applications requiring vibration resistance and durability.

Specification Summary & Compliance

This fastener features a No. 6 screw size with a 3/4" length, 18 TPI thread pitch, and 0.138" thread diameter, adhering to standard inch measurements for precision. The thread forming (Type A/AB) tapping method ensures reliable performance without pre-threaded holes. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of hazardous substances and supporting environmental regulations in industrial supply chains.
