Wacker Neuson 5200007316 Screw M16 X 40 Hex Head 10.9

The Wacker Neuson Screw M16 X 40 Hex Head 10.9 is a genuine OEM fastener designed for a broad range of Wacker Neuson equipment, including the RD27-100 and RD27-120 tandem rollers, HSH380S hydronic surface heaters, E1250S and E1250P hydronic heaters, and the HIF600 flameless air heater. As a direct factory-sourced component, this screw matches the exact grade, thread pitch, and head geometry specified at the time of manufacture. Proper fastener grade is critical across these machine families — the 10.9 property class rating indicates a high-tensile alloy steel construction engineered to handle the clamping loads and vibration stresses found in compaction and heating equipment. Replacing worn, stretched, or damaged fasteners with the correct OEM specification helps maintain the integrity of critical assemblies and keeps your equipment operating as intended.

Key Features

• Grade 10.9 High-Tensile Construction — Alloy steel at property class 10.9 delivers the elevated proof load and tensile strength required in high-stress, high-vibration assemblies on compaction and heating equipment.
• Genuine OEM Specification — Sourced directly from Wacker Neuson, this screw matches the exact M16 x 40 dimensions, thread form, and head style called out in the original engineering drawings — no substitution guesswork.
• Hex Head Drive — Standard hex head profile accepts common wrench and socket tooling, enabling straightforward installation and torque application to specification without special adapters.
• Wide Cross-Family Fitment — Confirmed fit across RD27-100 and RD27-120 tandem rollers, HSH380S hydronic surface heaters, E1250S and E1250P hydronic heaters, and the HIF600 flameless air heater — one part number, multiple platforms.
• Structural Integrity Assurance — Using the correct fastener grade prevents joint relaxation, bolt fatigue, and assembly loosening that can develop over time when an under-rated substitute is installed in a high-load position.

An M16 x 40 hex head screw at property class 10.9 is a structural fastener used to clamp and secure major assemblies where high clamping force and resistance to vibration-induced loosening are required. The 10.9 grade designation means the bolt is manufactured from medium-carbon alloy steel and heat-treated to achieve a minimum tensile strength of 1,000 MPa — significantly stronger than a common Grade 8.8 fastener. When a fastener in this role stretches, corrodes, or is replaced with a lower-grade substitute, joint preload drops, mating components can shift under load, and structural failures or accelerated wear in connected parts may follow.
