Wacker Neuson 5000028949 Hexagonal Flange Head Screw

The Wacker Neuson is a genuine OEM Hexagonal Flange Head Screw designed for a broad range of Wacker Neuson equipment, including RD-series tandem rollers, RT-series vibratory trench rollers, CRT-series ride-on concrete trowels, G-series mobile and portable generators, LTN and LTW light towers, PT and PTS trash pumps, HI indirect-fired air heaters, and several other machine families. As a genuine OEM component, the is manufactured to the exact material grade, thread specification, and dimensional tolerances specified by Wacker Neuson engineering. Sourcing the correct fastener by part number is critical across such a wide fitment range — thread pitch mismatches or incorrect flange geometry can compromise clamping force and lead to assembly failures in the field.

Key Features

• Genuine OEM Thread and Flange Integrity — Manufactured to Wacker Neuson's exact thread pitch, shank diameter, and flange diameter spec, ensuring full clamping load is achieved at the designed torque value without stripping or deforming mating surfaces.
• Integrated Flange Eliminates Separate Washer — The built-in flange distributes clamping load across a wider bearing surface, allowing direct installation without a loose washer — the same configuration used on the original assembly.
• Broad Cross-Family Fitment — A single part number covers applications across RD tandem rollers, RT and RTL trench rollers, CRT ride-on trowels, G-series generators, LTN and LTW light towers, PT and PTS trash pumps, and HI indirect-fired air heaters.
• Correct Clamping Force for Vibration-Prone Assemblies — Many of the machines in this fitment range generate significant operational vibration. Using the specified fastener with the correct head geometry helps maintain joint integrity and prevents loosening under sustained vibration loads.
• Critical Fastener for Structural and Mechanical Joints — In machine families such as vibratory rollers, trench rollers, and concrete trowels, fastener failure at key joints can create safety hazards. Using the correct OEM-specified part number is essential when replacing hardware in load-bearing or structural locations.

A hexagonal flange head screw combines a standard hex-drive bolt with an integrated flanged washer formed as part of the head. The flange spreads the clamping load over a larger surface area than a plain hex bolt head alone, reducing the risk of surface damage, pull-through, or localized stress on the mating component. This design is common in equipment assemblies where vibration is present and reliable joint clamping must be maintained over extended service intervals. When a fastener of this type wears, corrodes, or is replaced with an incorrect thread pitch or flange size, the resulting reduction in clamping force can allow joints to loosen progressively — leading to component misalignment, accelerated wear on adjacent parts, or structural failure depending on the application.
