The Wacker Neuson Hexhead Screw is a genuine OEM component designed for the LTN4Y, LTN5Y, and RD7Yeh series machines. As a factory-authorized part, it is manufactured to the exact material grade, thread pitch, and dimensional tolerances specified for these units. Compatibility extends across a broad range of configurations including standard, high-resistance, and low-resistance variants within the LTN and RD series lineups. Using the correct OEM screw ensures the fastened assembly is held at its engineered clamp load — no guesswork, no improvised substitutions.
Key Features
- OEM Thread and Grade Integrity — Manufactured to the exact tensile grade and thread specification called out in the Wacker Neuson parts documentation, ensuring the fastener performs as intended within the assembly.
- Drop-In Replacement — Matches the original head configuration, thread form, and shank dimensions for straightforward installation without reworking mating hardware.
- Broad Series Compatibility — Fits a wide range of LTN4Y, LTN5Y, and RD7Yeh series configurations including 60 Hz, 120V/60Hz, SA, CH, UK, RH, HD, and HRC/LRC variants, as well as the RD10Yehf LRC.
- Maintains Clamp Load — A correctly specified hexhead screw sustains the designed clamping force across the joint; an undersized or incorrect-grade fastener can loosen under vibration, leading to assembly failures in demanding operating conditions.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100006678 carries the same quality assurance as every component that ships in a new machine.
A hexhead screw is a threaded fastener used to clamp two or more components together within a machine assembly, tightened with a wrench or socket against a bearing surface. The hex head design allows consistent, measurable torque to be applied, which is critical in applications subject to vibration — such as light towers and compaction equipment — where fasteners must maintain their clamp load throughout the service life of the machine. When a hexhead screw wears, strips, or is substituted with an incorrect grade or size, the joint can loosen or fail entirely, potentially causing component misalignment or structural damage to the surrounding assembly.
