170861 - Miller Steel Stud 3/8-16 x 17.375 Replacement Hardware

Precision Engineering for Miller Welding Machines

The Miller 170861 Stud, Stl .375-16 X 17.375 is a specialized fastening component engineered for specific Miller welding power sources and auxiliary equipment. As a critical element of the machine's assembly, this stud is manufactured to strict tolerances to ensure proper alignment and structural integrity. Professional welding technicians and equipment repair specialists understand that substituting OEM hardware with generic alternatives can lead to compromised performance, vibration issues, or assembly difficulties.

Technical Specifications and Fitment
This stud is machined from robust steel, selected for its balance of strength and ductility. It features a 3/8-16 UNC thread profile (.375-16), a common yet robust coarse thread standard used in heavy machinery for its resistance to stripping and cross-threading. The total length of the stud is 17.375 inches (approximately 17 and 3/8 inches). This specific length is often utilized in through-bolt applications where the stud must pass through multiple chassis layers, transformer laminations, or component brackets to secure the main assembly of the power source.

Installation and Maintenance
When replacing a damaged or bent stud, it is essential to verify the condition of the mating nuts and washers. If the original stud failed due to over-torquing or fatigue, inspecting adjacent hardware is recommended. The Miller 170861 is designed for straightforward installation, matching the original factory specifications perfectly. Its steel construction ensures it can handle the torque requirements necessary to keep heavy internal components, such as transformers and rectifiers, firmly in place, minimizing the risk of internal movement that could lead to electrical shorts or mechanical noise.

Why Choose OEM?
While threaded rod stock is widely available, it often lacks the specific grade verification and finish quality of an OEM part. The Miller 170861 is guaranteed to meet the load-bearing requirements calculated by Miller's engineering team for your specific machine model. Ensure your repairs adhere to factory standards by utilizing only genuine Miller Electric replacement parts.
