Wacker Neuson 5000085957 Screw M8 X 30 Hexagon Head Serrated Flange

The Wacker Neuson is a genuine OEM Screw M8 X 30 Hexagon Head Serrated Flange designed for a broad range of Wacker Neuson equipment including the RT82-SC2 and RT56-SC2 Vibratory Trench Rollers, CRT48 Ride-on Trowels, and G-Series Mobile Generators spanning the G25 through G320. As a genuine OEM part, the is manufactured to the exact specifications of the original hardware, ensuring correct thread engagement, clamping load, and flange geometry every time. This screw sees use across an extensive lineup of Wacker Neuson machines, making it a practical stock item for fleet operators and service technicians who maintain multiple units. Confirm your model and serial number against the fitment list before ordering to ensure this is the correct fastener for your application.

Key Features

• OEM-Correct Thread and Flange Specification — M8 X 30 sizing with an integrated serrated flange delivers the precise clamping load and vibration resistance called for in the original Wacker Neuson assembly.
• Serrated Flange Locking Action — The built-in serrations bite into the mating surface during torquing, providing mechanical resistance to loosening under vibration — critical on compaction and power generation equipment.
• Direct Hardware Replacement — Matches the original fastener profile for drop-in installation without reworking the host component or using secondary locking hardware.
• Wide Cross-Equipment Fitment — Compatible with RT82-SC2 and RT56-SC2 Trench Rollers, CRT48 Ride-on Trowels, LTW20Z Light Towers, and G25 through G320 Mobile Generators, among many other Wacker Neuson models.
• Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson's authorized parts supply, so material grade, thread form, and surface treatment match what was installed at the factory.

A hexagon head serrated flange screw combines the fastening function of a standard hex bolt with an integrated flange that spreads clamping load across a wider bearing area and eliminates the need for a separate washer. The serrations machined into the underside of the flange dig into the clamped surface as the fastener is tightened, creating a mechanical lock that resists self-loosening caused by vibration or cyclic loading — exactly the conditions present in compaction rollers, trowels, and generators running in the field. When this type of fastener is worn, cross-threaded, or substituted with an incorrect grade or size, the joint can work loose over time, leading to misaligned components, accelerated wear on surrounding parts, or — in structural locations — potential mechanical failure.
