More About Part Number 499543

These 4-40 x 3/8" Thread Cutting Screws feature a Hex Washer Head with a Slotted Drive and are made from 18-8 Stainless Steel. Thread cutting screws create mating threads by cutting into the material during installation, making them useful where a screw must form secure threads in preformed holes. Type F thread cutting screws are designed to cut machine-quality threads in sheet metal, castings, 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 Hex Washer Head incorporates a built-in washer flange beneath the head, increasing bearing surface and improving load distribution while remaining compatible with standard hex drivers. A Slotted drive features a single straight groove that accommodates a flathead screwdriver for simple manual installation.
