Miller M4 x 55mm Socket Head Cap Screw (Pack of 2)

Genuine Miller Replacement Hardware for Reliable Repairs

Maintain the structural integrity and reliability of your Miller welding machine with the genuine Miller 270197 Screw. When performing maintenance or repairs on your welder, using the correct hardware is just as important as replacing the electronic components. This M4 x 55mm socket head screw is the exact part specified by Miller engineers for your equipment. Unlike generic hardware store fasteners, this OEM screw is manufactured to Class 12.9 steel standards, providing exceptional strength and durability. This is particularly important in welding environments where machines are subject to constant vibration, thermal expansion, and rough handling. A lower-grade screw could shear or loosen over time, leading to rattling components or internal electrical faults.

The socket head design features a hex drive, allowing you to tighten the fastener securely with a standard metric Allen key. This is essential for reaching deep into the machine chassis where other tools might not fit. The 55mm length is specific to certain assembly stacks within Miller power sources, ensuring the bolt engages fully with the mating threads without bottoming out or protruding dangerously. This package includes two screws, making it a convenient solution for replacing lost or stripped fasteners during a service interval. Don't risk the performance of your professional equipment with mismatched bolts; ensure a perfect fit and factory-level security with these authentic Miller replacement parts.
