Key Features

• OEM Grade 10.9 Tensile Strength — Manufactured to the 10.9 property class rating, delivering the clamping force and shear resistance the original assembly demands.
• Integrated Flange Head Design — The built-in flange distributes load across a wider bearing surface without a separate washer, fitting directly into existing mounting points as originally assembled.
• Correct M8x20 Thread and Length — Exact M8 thread diameter and 20 mm shaft length ensure full thread engagement and flush seating in the host component.
• C16 Material Specification — Manufactured to the C16 material grade, matching the corrosion resistance and hardness profile of the original fastener.
• Verified Fit for the G25 Generator Series — Confirmed compatible with the Wacker Neuson G25 platform, so you can order with confidence that 5100077046 is the right part for your machine.

A hex flange head screw serves as a structural fastener that clamps and secures components within the generator assembly. The integrated flange acts as a built-in load-spreader, reducing stress concentration at the joint and maintaining consistent clamping force during operation and vibration. Using a fastener with the correct grade and dimensions is critical — an under-spec or incorrectly sized screw can back out, strip, or allow joined components to shift, leading to misalignment or accelerated wear on surrounding parts.
