Wacker Neuson 5100069445 Iso 8678 M16x70 8.8 Znc

The Wacker Neuson Iso 8678 M16x70 8.8 Znc is a genuine OEM fastener designed for the LTW20Z1 Light Tower with LED and the LTV6L Light Tower series. As a direct Wacker Neuson OEM part, is manufactured to the exact material grade and dimensional spec called out in the original equipment build — no guesswork on thread pitch, shank length, or zinc coating grade. This bolt is confirmed for use across both the LTW20Z1 and LTV6L platforms, making it a straightforward service replacement for technicians working on these light tower units.

Key Features

• Grade 8.8 Tensile Rating — Medium-high strength carbon steel construction meets the load and torque demands of the structural mounting application this fastener is specified for.
• Zinc-Coated Finish (ZNC) — Factory-applied zinc coating provides corrosion resistance suited to outdoor light tower operating environments and extended service intervals.
• M16x70 Thread and Length Compliance — Exact M16 thread form and 70 mm shank length drop straight into the OEM threaded bore with no rework to mating hardware required.
• Verified OEM Fitment — Confirmed for the LTW20Z1 (LED) Light Tower and LTV6L Light Tower, covering both primary light tower platforms in this Wacker Neuson lineup.
• Structural Integrity Assurance — Using the correct grade and spec fastener ensures clamping force is maintained at design value; an under-spec substitute risks joint loosening under vibration load during operation.
• Genuine Wacker Neuson Part — Sourced directly through authorized Wacker Neuson supply channels, so the part number, grade marking, and coating spec match the original exactly.

An ISO 8678 hexagon bolt is a structural fastener used to clamp and secure major assemblies within the machine — in a light tower application this typically means mast, frame, or generator mounting joints that must maintain precise clamping force through continuous engine vibration and transport loads. The grade designation (8.8) defines the bolt's minimum yield and tensile strength, and the zinc coating (ZNC) protects the fastener shank and threads from rust in outdoor service. When a fastener of the wrong grade or dimensions is used in its place, the joint can lose preload over time, leading to movement, wear on mating surfaces, and potential structural loosening that affects safe operation of the light tower.
