164734 - Miller 164734 Plastite Screw K40x12 Hex Washer Head (10-Pack)

Restore Your Miller Welder with Authentic OEM Parts

When repairing your Miller welding machine, every detail matters—down to the last screw. The Miller 164734 Screw, K40X 12 Hex Washer Head is a specific replacement fastener used across a wide range of Miller power sources and wire feeders. This 10-pack ensures you have the necessary hardware to replace stripped, lost, or damaged screws during routine maintenance or deep repairs.

Why Use Genuine Miller Screws?

Welding machines are subjected to constant vibration, thermal cycling, and rough handling. The screws holding the chassis and plastic components together must be engineered to hold fast under these conditions. The 164734 is a Plastite self-tapping screw, designed to bite securely into plastic bosses without causing stress fractures. Using generic screws with the wrong thread pitch can destroy the mounting points on your expensive machine's case, leading to costly housing replacements. Stick to the OEM specification to preserve the value and functionality of your equipment.

Technical Specifications

This screw features a K40 x 12 size profile, indicating its specific diameter and length tailored for Miller's plastic assemblies. The Hex Washer Head (HexwHD) provides a broad bearing surface that distributes clamping force evenly, preventing the screw head from pulling through softer plastic materials. Additionally, the slotted drive offers a backup method for removal if a hex driver is unavailable. The steel construction is plated to resist oxidation, ensuring the screw doesn't seize or rust over time.

Verify Your Fitment

Before ordering, we recommend checking your machine's parts manual to confirm the location and quantity of the 164734 screw required. Whether you are reassembling a machine after blowing out dust or replacing a cracked front panel, these screws provide the factory-correct finish and security your Miller welder deserves. Keep a pack in your toolbox so you are never stuck searching for the right fastener during a critical repair.
