Wacker Neuson 1000401340 Hex Screw DIN933 M16x70 10.9 Dacro 500-5

The Wacker Neuson is a genuine OEM Hex Screw DIN933 M16x70 10.9 Dacro 500-5 designed for PT6YT and PT6Y series self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this fastener meets the exact DIN 933 standard, M16x70 sizing, and Grade 10.9 tensile rating specified for these high-capacity 6-inch discharge pumps. The Dacro 500-5 coating provides robust corrosion resistance suited to the demanding wet and muddy environments where PT6 series pumps are routinely deployed. Confirm part number against your machine's parts diagram before ordering to ensure a direct match for your specific pump configuration.

Key Features

• Grade 10.9 Tensile Strength — High-strength fastener rated to DIN 933 Grade 10.9, delivering the clamping force required to maintain structural integrity under continuous pump vibration and pressure loads.
• Dacro 500-5 Corrosion Protection — The Dacro 500-5 zinc-flake coating guards against rust and chemical attack, extending service life in wet, muddy, and chemically aggressive pumping environments.
• Exact DIN 933 M16x70 Specification — Full-thread hex bolt conforms to DIN 933 geometry at M16x70, ensuring correct thread engagement and torque retention on reinstallation.
• Genuine OEM Part — Manufactured to Wacker Neuson's original specification, so dimensions, thread pitch, and coating grade match the fastener your pump left the factory with.
• Fits PT6YT and PT6Y Series Trash Pumps — Verified fitment across PT6YT, PT6YT-IN, PT6Y, and PT6Y EPA T4 pump models, covering a wide range of production configurations in the PT6 family.

A hex screw of this grade and size serves as a critical structural fastener within the PT6 series pump assembly, securing major components — such as the pump casing, volute, or mounting brackets — that must remain rigidly fixed during high-volume fluid transfer operations. At Grade 10.9, the fastener is engineered to withstand the tensile and shear forces generated by pump vibration and hydraulic pressure without stretching or loosening over time. When a fastener of this type fails or is replaced with an incorrect grade or coating, it can lead to joint movement, casing misalignment, fluid leaks, or accelerated wear on surrounding components.
