Au-ve-co Products 23869 Hex Head Sheet Metal Screw M4.2

Product Description

The AU-VE-CO PRODUCTS 23869 is an M4.2 hex head sheet metal screw designed for fastening sheet metal components in HVAC, mechanical, and light-gauge steel fabrication applications. The hex drive head allows for wrench or socket installation, providing consistent torque and a secure, vibration-resistant connection. The Type B point is a blunt-tipped, thread-cutting design suitable for pre-drilled or punched holes in light sheet metal. At 18 millimeters in length, this screw is suited for standard panel-to-panel or panel-to-frame connections. Material is steel throughout. Minimum order quantity is 50 pieces per package.

This screw is commonly used by HVAC technicians, sheet metal workers, and mechanical contractors assembling ductwork, access panels, equipment enclosures, and similar light-gauge steel assemblies. The hex head profile is preferred in production and service environments where a nut driver or socket wrench is used for speed and consistent drive depth. Its compact M4.2 thread size fits standard pre-punched sheet metal gauges typical in residential and light commercial HVAC equipment.

Installation Notes

Installation is typically performed by HVAC technicians or sheet metal workers using a nut driver, hex socket, or adjustable wrench sized for the hex head. Ensure the receiving material has an appropriate pre-drilled or punched pilot hole to match the Type B point specification. Power down any associated electrical equipment before fastening panels or enclosures. Avoid overtightening, which can strip threads in light-gauge sheet metal.
