Professional Applications & Engineering Value
These No. 6 x 3/8" zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and installation efficiency are critical. The thread forming design eliminates the need for pre-tapped holes, creating strong internal threads that resist loosening under vibration and thermal cycling. The slotted pan head configuration provides excellent torque transmission while the fully threaded shank ensures maximum material engagement in thin gauge metals up to 0.025" thickness. These A/AB type tapping screws with 18 threads per inch deliver superior pull-out resistance, making them ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment where sheet metal fastening demands precision and durability.
Specification Summary & Compliance
These inch-system fasteners feature precision Class 2A thread tolerances with 0.138" thread diameter and 18 TPI thread pitch. The thread forming tapping method complies with standard industrial specifications for type A/AB sheet metal screws. Manufacturing and material composition fully adhere to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring compliance for international industrial applications. Designed for use with No. 32 drill bit (0.116" diameter) in sheet metal up to 0.025" maximum drilling thickness.
