The Wacker Neuson Lock Nut is a genuine OEM fastener designed for a range of Wacker Neuson equipment including the WP1550R and WP1550RW vibratory plate compactors, PT2R centrifugal trash pumps, and the BFS floor saw series. Sourced directly from Wacker Neuson, this Lock Nut matches the original component specification used on the production line. It fits confirmed models including the BFS 1345B, BFS 130R, BFS 130RM, BFSX 130R, BFSX 130RM, BFS18D, BFS 1350L, BFS 1345BZ, and PT2R trash pumps, making it a versatile service part across multiple machine families. When replacing worn or missing fasteners, using the correct OEM part ensures proper torque retention and secure assembly.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to Wacker Neuson's original thread profile and hardness specification, so the locking action performs exactly as engineered.
- Cross-Family Fitment — A single part number that covers vibratory plate compactors (WP1550R, WP1550RW), centrifugal trash pumps (PT2R), and multiple BFS floor saw configurations.
- Direct Drop-In Replacement — Thread pitch, diameter, and locking collar geometry match the original, allowing straightforward installation without rework or adaptation.
- Secure Clamping Under Vibration — Lock nuts are specifically engineered to resist loosening in high-vibration environments — critical on compactors and floor saws where fastener backing-off can lead to component misalignment or damage.
- Broad BFS Floor Saw Coverage — Confirmed fitment across the BFS 1345B, BFS 1345BZ, BFS 130R, BFS 130RM, BFSX 130R, BFSX 130RM, BFS18D, and BFS 1350L models.
A lock nut is a specialized fastener designed to resist loosening caused by vibration, dynamic loads, or torque fluctuation during machine operation. Unlike a standard nut, it incorporates a locking mechanism — typically a prevailing-torque insert or a distorted thread section — that maintains clamping force even when the assembly is subject to continuous movement. On vibratory plate compactors and floor saws in particular, fasteners are exposed to sustained high-frequency vibration, and a lock nut that has backed off or failed can allow critical components to shift out of alignment, accelerate wear on surrounding parts, or create unsafe operating conditions. Replacing a worn or lost lock nut promptly with the correct OEM part restores the engineered clamping load and keeps the assembly secure through demanding work cycles.
