The Wacker Neuson is a genuine OEM Hex Screw M16x50 10.9 Dacro DIN933 designed for the PT6YT and PT6Y series self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this fastener carries the full OEM designation, ensuring it meets the exact material grade, thread specification, and corrosion-resistance standard called out in the original build. Fitment is confirmed across multiple PT6YT and PT6Y machine configurations, including EPA Tier 4 variants, making the correct replacement regardless of which production run your pump represents.
Key Features
- Grade 10.9 High-Tensile Strength — The 10.9 property class rating delivers the clamping force required for structural and load-bearing fastener positions on heavy-duty pump assemblies, resisting loosening under vibration and operational stress.
- Dacromet Corrosion Protection — The Dacro (Dacromet) coating provides superior resistance to rust and chemical attack compared to standard zinc plating, making this screw well-suited to the wet, debris-heavy environments trash pumps regularly operate in.
- DIN933 Full-Thread Hex Bolt Standard — Conforms to DIN933 geometry with a full-length thread profile, ensuring correct engagement depth and consistent torque values when installed per Wacker Neuson service specifications.
- Confirmed OEM Fitment for PT6YT and PT6Y Series — Verified across PT6YT, PT6YT-IN, PT6Y, and PT6Y EPA T4 pump variants, so you can order with confidence without cross-referencing multiple part numbers.
- Genuine Wacker Neuson OEM Part — As an authentic OEM fastener, 1000085430 is manufactured to the same thread class tolerances and coating specification as the original hardware, preserving the structural integrity of critical pump joints.
A hex screw of this grade and size serves as a primary structural fastener in heavy-duty pump assemblies, securing major components — such as engine mounts, pump housings, or frame connections — that must withstand continuous vibration, hydraulic forces, and outdoor exposure. The M16x50 dimensions and grade 10.9 rating mean this fastener is engineered to carry significant clamping loads; substituting an incorrect grade or coating can lead to fastener fatigue, joint loosening, or accelerated corrosion that compromises the integrity of the entire assembly. Replacing a worn or damaged hex screw with the correct OEM specification part restores the pump to its designed clamping and torque retention performance.
