• Optimized for sheet metal applications with No. 6-18 thread size and 3/4" length, delivering reliable grip in 0.025" maximum thickness materials
• Broad industrial compliance with RoHS 3 and REACH regulations, ensuring safe usage in global manufacturing operations
• Secure rounded pan head profile providing consistent clamping force without damaging material surfaces

Professional Applications & Engineering Value

These No. 6-18 x 3/4" zinc-plated steel tapping screws solve critical industrial fastening challenges in sheet metal applications where traditional fasteners fail. The thread forming design creates strong, permanent threads in parent material without chips or debris, eliminating the need for separate tapping operations and reducing assembly time by up to 50%. The T15 Torx drive system delivers exceptional torque transmission compared to Phillips or slotted drives, preventing strip-out during high-torque installation in automated production environments. Combined with the fully threaded pointed tip, these screws provide immediate engagement and pull-through resistance in thin-gauge metals up to 0.025" thickness, making them ideal for HVAC systems, electronic enclosures, and automotive panels where vibration resistance and structural integrity are paramount.

Specification Summary & Compliance

These tapping screws feature precise No. 6-18 thread specifications with 0.138" thread diameter and right-hand threading, manufactured to industry standards for sheet metal fastening. The thread forming (Type A/AB) design ensures proper fit without pre-tapped holes when used with recommended No. 32 drill bit (0.116" diameter). Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming they contain no restricted substances for industrial safety and environmental protection.
