Wacker Neuson 5000175378 Carriage Bolt Grade 5 5/8-11x1-3/4

The Wacker Neuson is a genuine OEM Carriage Bolt Grade 5 5/8-11x1-3/4 designed for the G100 and G120 mobile generator series, the MGT3.1S trailer, and compatible Wacker Neuson angle broom attachments. Sourced directly from Wacker Neuson, this bolt meets the exact material grade and thread specification called out in the original equipment design. Grade 5 medium-carbon steel construction delivers the tensile strength needed to maintain secure, vibration-resistant connections in demanding outdoor and jobsite environments. If you are servicing a G100 generator, G120 generator, MGT3.1S dual-axle trailer, or a 72-inch or 84-inch angle broom, part number is the correct bolt for the application.

Key Features

• Grade 5 Tensile Strength — Medium-carbon steel with Grade 5 classification provides the clamping force and shear resistance required for structural fastener positions on generators, trailers, and broom attachments.
• Correct Thread Engagement — 5/8-11 coarse thread and 1-3/4-inch shank length match the original tapped holes exactly, ensuring full thread engagement without bottoming out or under-threading.
• Genuine OEM Part — Manufactured to Wacker Neuson specification, so the head diameter, dome profile, and surface finish align with the original hardware throughout the assembly.
• Broad Fitment Across Multiple Machines — Confirmed for G100 and G120 mobile generators across multiple serial configurations, the MGT3.1S surge-brake dual-axle trailer, and 72-inch and 84-inch angle broom attachments.
• Vibration-Resistant Connection — The smooth domed carriage bolt head and square neck prevent rotation during torquing, maintaining joint integrity on equipment that operates under sustained vibration and load cycles.

A carriage bolt is a through-fastener designed with a smooth, rounded head and a square shoulder beneath it that locks into a mating hole, preventing the bolt from spinning as a nut is tightened on the opposite side. This design makes it the preferred fastener choice for structural panel connections, frame mounting points, and attachment brackets where a flush or snag-free surface is required. When a carriage bolt is worn, stripped, or of the incorrect grade, joint integrity is compromised — leading to loosening under vibration, misalignment of attached components, or fastener failure under load.
