Professional Applications & Engineering Value

These No. 6 x 1/4" zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the need for pre-tapped holes while creating stronger thread engagement than cutting alternatives. The A/AB screw type with right-hand threading and fully threaded design ensures uniform stress distribution, preventing loosening under dynamic loads. The slotted pan head provides reliable drive engagement while the zinc plating offers essential corrosion protection for demanding industrial environments. Engineered specifically for 0.025" maximum drilling thickness, these fasteners solve common assembly challenges in HVAC, electrical enclosures, and metal fabrication where precision and durability are paramount.

Specification Summary & Compliance

These thread forming sheet metal screws feature precise Class 2A thread tolerances with 0.138" thread diameter and 18 threads per inch configuration. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial applications. The slotted drive style and pan head design meet industry standards for sheet metal fastening applications, while the pointed tip and fully threaded construction provide consistent performance across various metal thicknesses up to the specified maximum drilling capacity.
