Handle Bolt (New Style) | WP1540, WP1550

The Wacker Neuson is a genuine OEM Hexagonal Head Cap Screw designed for a wide range of Wacker Neuson compaction equipment, including DPU reversible vibratory plate compactors, VP and WP single-direction vibratory plate compactors, and BS gasoline vibratory rammers. Sourced directly from Wacker Neuson, this fastener meets the exact material grade, thread specification, and head geometry called out in the original equipment build. It is a direct-fit replacement confirmed across the DPU 5545H, DPU 4545H, VP1030A/Aw through VP2050A/Aw, WP1540A/Aw, WP1550A/Aw, and BS50-2, BS50-4As, and BS65-4As model families. Using the correct OEM fastener ensures proper clamping load and torque retention at every installation point where this screw is specified.

Key Features

• OEM-Grade Fastener Material — Manufactured to Wacker Neuson's specified material grade and tensile strength, ensuring the screw holds the correct clamping load without stretching or backing out under vibration.
• Correct Thread Form and Head Geometry — Hex head dimensions and thread pitch match the original hardware exactly, allowing proper installation with standard tooling and full thread engagement in the mating bore.
• Broad Cross-Family Fitment — A single genuine OEM part number that covers DPU reversible plates, VP and WP single-direction vibratory plates, and BS gasoline rammers — simplifying parts stocking for fleets running mixed Wacker Neuson compaction equipment.
• Vibration-Environment Reliability — Compaction equipment generates sustained high-frequency vibration; an underspec or worn fastener in this environment will loosen prematurely, leading to component misalignment or structural failure at the joint.
• Genuine OEM Traceability — Carries the Wacker Neuson OEM part number 5000220523, making it straightforward to verify against your machine's parts manual before ordering.

A hexagonal head cap screw is a standard threaded fastener used to clamp two or more components together at a fixed, load-bearing joint. In compaction equipment — where the entire machine transmits high-frequency vibration forces through its frame — fasteners are a critical structural element, not merely hardware. A screw of the wrong tensile grade, incorrect thread pitch, or improper head dimensions can back out under cyclic loading, strip the receiving thread, or fail to develop the clamping force needed to keep assemblies aligned and intact. Replacing a worn or damaged fastener with the correct OEM-specified part restores the joint to its designed clamping specification and prevents recurring loosening or component damage.
