Wacker Neuson 5000025555 Screw 3/8-16 x 1-1/4 Grade 5 Hex Head

The Wacker Neuson is a genuine OEM Screw 3/8-16 x 1-1/4 Grade 5 Hex Head designed for use across a wide range of Wacker Neuson equipment, including the RD12A tandem roller, GP and GPS portable generator series, CT walk-behind concrete trowel series, CRT ride-on trowel series, PT and PDT trash pump series, LTN6C light tower, and WB16A power buggy line. As a genuine OEM part sourced directly from Wacker Neuson, is manufactured to the exact thread pitch, length, and grade specification called out in the original equipment design. This Grade 5 hex head fastener covers one of the broadest cross-equipment fitment ranges in the Wacker Neuson parts catalog, making it a smart stocking item for fleet operators and service shops supporting multiple machine types.

Key Features

• Grade 5 Tensile Strength: — Heat-treated to Grade 5 specification, delivering the clamping force and shear resistance required in vibration-intensive equipment like rollers, trowels, and pumps.
• Correct Thread Form for Direct Installation: — 3/8-16 UNC thread form matches the tapped holes in Wacker Neuson equipment exactly, allowing straightforward installation with standard hand tools.
• Broad Cross-Equipment Compatibility: — A single part number covers the RD12A tandem roller, GP/GPS portable generator series, CT and CRT concrete trowel families, PT and PDT trash pump series, LTN6C light tower, and WB16A power buggy models.
• Genuine OEM Specification: — Sourced directly from Wacker Neuson, this fastener meets the precise dimensional and material standards specified for each machine it serves — not a generic hardware substitute.
• Prevents Loosening Under Vibration: — Equipment that relies on a correctly torqued Grade 5 fastener maintains structural integrity at panel, frame, and component attachment points; an undersized or incorrect-grade substitute risks working loose during operation.

A hex head cap screw like the Wacker Neuson 5000025555 serves as a structural fastener at panel, housing, guard, and component mounting points throughout the machine. At 3/8-16 UNC thread and 1-1/4 inch length, it provides the clamping load needed to keep assemblies secure under the continuous vibration and load cycles that construction equipment experiences in the field. Using a fastener of the correct grade and dimensions is critical — an incorrect grade can stretch or shear under torque, while an incorrect length can bottom out in a blind hole or fail to engage enough thread, both of which compromise the integrity of the joint over time.
