Wacker Neuson 5000011543 Screw M8 X 20 Socket Head

The Wacker Neuson Screw M8 X 20 Socket Head is a genuine OEM fastener designed for a wide range of Wacker Neuson equipment including BS50, BS60, and BS70 series vibratory rammers, RD12, RD16, and RD27 tandem rollers, RT and RTL trench rollers, CRT ride-on trowels, CT walk-behind trowels, DPU and BPU reversible vibratory plates, VP and WP single-direction vibratory plates, and PT trash pumps. As a direct OEM replacement sourced from Wacker Neuson, part number is manufactured to the same specification as the original hardware installed at the factory. This M8 x 20mm socket head cap screw is used across dozens of Wacker Neuson model variants, making it a smart stocking fastener for dealers, rental fleets, and service technicians who support multiple machine types.

Key Features

• Genuine OEM Fastener Grade: — Manufactured to Wacker Neuson's specified thread class and tensile grade for M8 socket head cap screws — ensuring proper clamp load and joint integrity across every application.
• Hex Socket Drive: — The internal hex (Allen) socket drive allows precise torque application with a standard hex key or socket, even in tight or recessed mounting locations common on rammer covers, roller frames, and trowel assemblies.
• Broad Cross-Model Compatibility: — A single part number covering BS50/60/70 rammers, DS70/DS720 diesel rammers, RD tandem rollers, RT/RTL/RTK trench rollers, CRT and CT trowels, DPU/BPU/VP/WP compaction plates, and PT pumps — one fastener serves your entire Wacker Neuson fleet.
• Correct Thread and Length for OEM Torque Specs: — At M8 x 20mm, this screw matches the original hole depth and engagement length; using an incorrect length risks under-engagement or bottoming out, both of which compromise joint strength.
• Prevents Fastener-Related Service Failures: — Worn, stripped, or incorrect-grade fasteners can allow covers, guards, and structural panels to loosen under vibration — replacing with the correct OEM screw restores the designed clamping force.

A socket head cap screw is a threaded fastener with a cylindrical head and an internal hexagonal recess that accepts an Allen key or hex bit driver. In construction equipment, socket head cap screws are used where a low-profile head is needed in recessed or confined mounting areas — such as access covers, engine mounts, exciter housings, and frame panels — where a standard hex bolt head would not clear surrounding structure. The M8 x 20mm designation defines the thread diameter (8mm) and the grip length (20mm), both of which must match the original specification to achieve the torque value required to keep joints secure under continuous vibration. When a fastener is the wrong grade, length, or thread pitch, it cannot achieve proper clamp load, allowing joints to work loose during operation and causing accelerated wear or damage to mating components.
