174828 - Miller M8 x 45mm Hex Head Screw Grade 8.8

Genuine Miller OEM Replacement Hardware

The Miller 174828 Screw, M 8-1.2X 45 Hex HD-Pln 8.8 Pln is a critical replacement component designed specifically for Miller welding equipment. When maintaining or repairing industrial machinery, utilizing the correct hardware is essential for ensuring the longevity and safety of the unit. This metric screw features an M8 diameter with a standard 1.25 thread pitch and a length of 45mm, making it a precise fit for specific assembly points within Miller power sources, wire feeders, or running gear.

Material Strength and Grade

Manufactured to Class 8.8 specifications, this fastener is constructed from medium carbon steel that has been quenched and tempered. Class 8.8 hardware provides a high tensile strength (approximately 800 MPa), which is significantly stronger than standard low-carbon hardware. This strength is vital for holding heavy internal components, chassis panels, or transformer assemblies securely in place, even under the vibration and thermal cycling common in welding environments.

Precision Fitment

Using non-OEM hardware can often lead to thread damage or insufficient clamping force. The Miller 174828 features a plain finish, which avoids the build-up associated with thick platings, ensuring a tight and accurate thread engagement. The hex head design allows for the application of substantial torque using standard metric wrenches or sockets, ensuring that the fastener stays tight during operation. Whether you are replacing a lost bolt during maintenance or repairing a damaged unit, this genuine Miller part guarantees the fit and performance intended by the manufacturer.

Application

This screw is used across various Miller product lines. Always verify the part number in your machine's owner's manual or parts breakdown to ensure this specific M8 x 45mm screw is the correct component for your repair location.
