Wacker Neuson 5000150913 Stud M8x20 5.8/8.8 Zc

The Wacker Neuson is a genuine OEM Stud M8x20 5.8/8.8 Zc designed for the RT560 and RT820 vibratory trench rollers. Sourced directly from Wacker Neuson, this stud meets the original engineering specifications for strength grade and zinc-chromate corrosion protection. It is a direct-fit replacement that installs exactly as the factory-original component, with no guesswork on thread pitch, length, or grade. Confirmed fitment covers RT560 and RT820 series vibratory trench rollers.

Key Features

• Dual-Grade Rated Fastener — Manufactured to 5.8/8.8 strength grade specification, delivering the correct clamp load and shear resistance for the application.
• Zinc-Chromate Coating — The Zc finish provides corrosion resistance suited to equipment operating in wet trench and soil compaction environments.
• Genuine OEM Part — Supplied as an authentic Wacker Neuson component, ensuring correct thread form, length, and material grade as originally engineered.
• Direct Replacement for RT560 and RT820 — Fits RT560 and RT820 vibratory trench rollers; drop-in replacement that threads in using standard tooling.
• Structural Integrity Under Vibration — A correctly specified stud maintains joint clamping force through the constant vibration cycles of trench roller operation; an incorrect or worn stud risks joint loosening and component damage.

A stud fastener serves as a permanent or semi-permanent threaded rod that anchors two or more components together, with nuts or mating hardware applied to each exposed end. In a vibratory trench roller like the RT560 and RT820, fasteners are subjected to continuous oscillation and ground-reaction forces, making correct grade and dimensional accuracy critical to maintaining structural integrity. When a stud fails, stretches, or corrodes, joint clamping is lost, which can lead to component movement, accelerated wear, and potential mechanical failure of the assembly it secures.
