Professional Applications & Engineering Value

Engineered for demanding sheet metal applications, these No. 4-24 thread forming screws eliminate the need for pre-tapped holes while creating strong, wear-resistant threads in metal substrates. The zinc-plated steel construction provides essential corrosion protection in manufacturing facilities, HVAC systems, and electronic enclosures. With fully threaded engagement and Phillips/Slotted drive compatibility, installers achieve maximum clamp load distribution while accommodating both power and manual driving tools. The pan head design offers low-profile clearance requirements while maintaining sufficient bearing surface for secure sheet metal-to-frame connections.
