S-90054A151 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced installation efficiency through combined external hex/slotted drive that accommodates multiple tool types
• Maximum material engagement with fully threaded design and pointed tip for secure fastening in sheet metal up to 0.025" thick
• Increased load distribution thanks to the integrated flange design that prevents pull-through and reduces surface damage
• Reliable thread formation using A/AB type thread forming technology that creates strong, vibration-resistant connections
• Precision compatibility with No. 32 drill bits (0.116" diameter) for accurate hole preparation and optimal thread engagement
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 6-18 zinc-plated steel tapping screws are engineered specifically for sheet metal applications where vibration resistance and pull-out strength are critical. The thread forming technology creates precise mating threads in the base material without generating chips, eliminating contamination risks in sensitive assemblies. The flanged hex head design provides superior clamping force distribution while the external hex/slotted drive accommodates both manual and powered installation tools. With 18 threads per inch and 0.138" thread diameter, these screws deliver optimal thread engagement in thin-gauge materials up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, automotive panels, and industrial equipment where reliable metal fastening is essential.

Specification Summary & Compliance
