Description

Meet a robust Thread Rolling Screws alternative engineered to deliver dependable torque and secure seating in metal and hard plastics. These Phillips Flat Undercut Head screws are built from durable steel and finished with black oxide and a waxed coating for corrosion resistance and smooth driving. Sized #4-40 x 3/8, they are a practical choice for quick, secure assemblies in a variety of applications.

Overview

The Phillips drive works with standard screwdrivers, while the flat undercut head sits flush in countersunk or recessed holes for a clean, low-profile finish. The tri-lobe design enhances anti-rotation performance, ensuring consistent torque and seating across assemblies.
