163175 - Miller 163175 Screw, 1/4-20 x 0.75 Hex Head Stainless Steel (10-Pack)

Authentic Miller Replacement Hardware: 163175 Hex Head Screw

The Miller 163175 is a specified replacement fastener designed for the assembly and maintenance of Miller electric welding equipment. This product consists of a package of ten (10) hex head cap screws, engineered to meet the precise dimensional and material standards required by Miller Electric for their power sources and industrial machinery. Using genuine OEM hardware ensures structural integrity and proper grounding where applicable.

Technical Specifications:
This fastener features a .250-20 (1/4-20) UNC thread pitch with a length of 0.75 inches. The drive type is a standard external hex head, allowing for high-torque application using standard SAE sockets or wrenches. The specific material composition is Type 18-8 (302-305) Stainless Steel. This austenitic stainless steel grade offers excellent resistance to oxidation and corrosion, which is critical for equipment operating in industrial environments where humidity, fumes, and temperature fluctuations are common.

Application and Durability:
Stainless steel hardware is preferred in welding equipment design not only for its longevity but also for its non-magnetic properties in certain grades and its ability to maintain thread integrity over repeated assembly and disassembly cycles. Unlike zinc-plated or black oxide fasteners, the Miller 163175 will not succumb to surface rust that can seize threads and complicate future maintenance. These screws are commonly utilized for securing chassis panels, internal brackets, and protective covers on various Miller MIG, TIG, and Stick welders.

Maintenance Recommendation:
When performing routine maintenance or internal repairs on welding power sources, it is recommended to inspect all fasteners for wear or thread damage. Replacing damaged or missing hardware with the correct OEM specification prevents vibration-induced loosening and ensures the machine enclosure remains secure and compliant with safety standards. This 10-pack quantity provides maintenance teams with necessary inventory for immediate repairs.
