236847 - Miller #6-20 x 0.50 Flat Head Phillips Sheet Metal Screw

Genuine Miller OEM Replacement Hardware

The Miller 236847 Screw is a specialized fastening component designed specifically for the assembly and maintenance of Miller welding equipment. As an Original Equipment Manufacturer (OEM) part, this screw guarantees the precise dimensional tolerances required to maintain the structural integrity of your machine. Utilizing generic hardware in precision industrial equipment can often lead to mismatched thread pitches, improper seating, or galvanic corrosion issues. By choosing the authentic Miller 236847, you ensure that the replacement part meets the exact engineering standards set by the manufacturer during the initial design of the welder.

Technical Specifications and Design

This fastener features a #6-20 thread pitch, a standard designation for sheet metal screws that provides excellent holding power in thin-gauge metals. The 0.50-inch length is optimized to penetrate materials securely without protruding excessively into internal compartments where it might interfere with wiring or circuit boards. The screw utilizes a Type A point, which is characterized by a coarse thread and a sharp point, specifically engineered for forming threads in sheet metal, resin-impregnated plywood, or asbestos combinations. This self-tapping capability simplifies installation and ensures a tight, vibration-resistant bond.

Material and Durability

Constructed from high-quality steel, this screw offers the tensile strength necessary to withstand the mechanical stresses associated with heavy-duty welding machinery. The steel is treated with a plating finish—typically zinc or a similar protective coating—which provides a barrier against oxidation and rust. In welding environments, where equipment is frequently exposed to humidity, fumes, and temperature fluctuations, corrosion resistance is critical for preventing seized fasteners during future maintenance. The flat head design allows the screw to sit flush with the surface when installed in countersunk holes, preventing snagging and maintaining the sleek, professional appearance of your Miller equipment.

Application and Installation

This screw is commonly used to secure outer panels, access doors, and internal brackets within various Miller power sources and wire feeders. The Phillips drive style is universally recognized, allowing technicians to perform repairs using standard screwdrivers found in any toolbox. When installing, it is recommended to hand-tighten or use a low-torque setting on power drivers to avoid over-tightening, which could strip the sheet metal threads. Verifying the fitment using your machine's serial number is always advised to ensure this specific part number corresponds to your equipment's bill of materials.
