Wacker Neuson 5000084895 Hex Head Cap Screw 1-1/2 Lg

The Wacker Neuson is a genuine OEM Hex Head Cap Screw 1-1/2 Lg designed for the PD3B 75mm/3-inch diaphragm pump. Sourced directly through the Wacker Neuson parts program, this fastener is manufactured to the exact dimensions and material specification required for this application. Whether you are performing routine service or rebuilding after a failure, using the correct OEM hardware on the PD3B ensures the assembly goes back together to spec.

Key Features

• OEM-Grade Fastener Material — Manufactured to the tensile strength and dimensional tolerances specified for diaphragm pump assemblies, ensuring consistent clamping force and resistance to loosening under vibration.
• Exact 1-1/2 Inch Length — The 1-1/2 Lg specification matches the thread engagement depth of the PD3B housing, allowing the screw to seat flush without over- or under-penetration.
• Fits PD3B Diaphragm Pump — Confirmed fitment for the PD3B 75mm/3-inch diaphragm pump (machine number 5000006802), so you can order with confidence.
• Maintains Pump Integrity Under Pressure — A correctly torqued, properly sized cap screw keeps the pump housing sealed and aligned during operation; a stripped, undersized, or incorrect fastener can lead to housing separation and pump failure.
• Genuine Wacker Neuson OEM Part — Supplied as an authentic replacement through the Wacker Neuson parts catalog, carrying the same part number 5000084895 used by authorized service centers worldwide.

A hex head cap screw of this type is a critical fastener used to clamp and secure the housing sections of the PD3B diaphragm pump. It applies the compressive load needed to keep internal sealing surfaces seated, preventing leaks and maintaining the pump's ability to move fluid effectively. When a cap screw is damaged, corroded, or substituted with an incorrect length or grade, it compromises the clamping force across the pump body, which can result in housing misalignment, seal failure, or fluid escape during operation.
