S-94005A339 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding industrial environments.
• Efficient thread forming action creates strong, secure threads in sheet metal without pre-tapping, reducing installation time and labor.
• Reliable Phillips drive (No. 2 size) ensures common tool compatibility and prevents cam-out for consistent, secure fastening.
• Full threading and pointed tip enable quick, easy starts and maximum thread engagement for a stronger, more vibration-resistant hold.
• Optimized for 0.025" maximum drilling thickness with No. 32 drill bit compatibility, providing precise application guidance for sheet metal assemblies.
• Rounded head design offers a standard, low-profile finish that sits flush and minimizes snagging in assembled products.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and unrestricted use in global industrial supply chains.

Professional Applications & Engineering Value

These sheet metal tapping screws are engineered to solve common fastening challenges in metal fabrication and assembly. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making these A/AB type screws ideal for HVAC systems, electronic enclosures, and automotive panels exposed to moisture or harsh conditions. The thread forming design eliminates the need for separate tapping operations, as the screw creates its own precise mating threads in the sheet metal, reducing assembly steps and potential for cross-threading. This fully threaded configuration with a pointed tip ensures rapid penetration and maximum holding power, critical for maintaining structural integrity in vibrating environments. The combination of a Phillips drive and standardized dimensions ensures compatibility with common power tools, streamlining production lines and reducing fastener failure risks.

Specification Summary & Compliance

This No. 6 x 3/4" screw features a 0.138" thread diameter with 18 threads per inch and a right-hand thread direction. The rounded head has a diameter of 0.26" and height of 0.103". Manufactured to A/AB tapping screw type standards for thread forming applications in sheet metal, it is designed for use with a No. 32 drill bit (0.116" diameter). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to strict environmental and safety standards for industrial components.
