More About Part Number 343792

These 4-40 x 3/8" Thread Forming Screws feature a Flat Head with a Phillips Drive and are made from 410 Stainless Steel. Thread forming screws create mating threads by displacing material rather than cutting it, making them useful in softer materials where strong thread engagement is desired. Taptite style thread forming screws are designed to reduce driving torque while creating strong mating threads in ductile metals and similar materials. They feature a Plain Finish, meaning no additional surface coating has been applied; this is commonly used where the part will be painted, plated, or used in controlled indoor environments. The Flat Head sits flush or countersunk with the material surface when fully installed, making it a strong choice for applications that require a smooth, low-profile finish. A Phillips drive features a cross-shaped recess designed for efficient installation with standard Phillips drivers and power tools.
