Wacker Neuson 5000080264 Screw 1/4-20 X 5/8 With Flat Washer, Hex Head

The Wacker Neuson is a genuine OEM Screw 1/4-20 X 5/8 With Flat Washer, Hex Head designed for Wacker Neuson G-series portable generators and RS800-series single drum vibratory rollers. As a direct OEM replacement, is manufactured to the exact thread pitch, head geometry, and integrated flat washer specification required by the original assembly. Fitment covers a broad range of G-series skid-mounted and mobile generator configurations — including the G25, G50, G70, G85, G125, and G160 — as well as RS800, RS800A, RSS800A, RS800H, and RS800V single drum vibratory roller models. Sourcing the correct fastener by part number eliminates the guesswork of matching thread count, grip length, and washer face diameter at the counter.

Key Features

• Genuine OEM Thread Integrity — Manufactured to the precise 1/4-20 thread specification, ensuring full thread engagement and correct clamp load in the original tapped holes.
• Integrated Flat Washer Design — The captive flat washer distributes clamping force across the mating surface, protecting panel faces and housings from fastener pull-through or surface damage.
• Broad Cross-Family Fitment — A single part number covers G25, G50, G70, G85, G125, and G160 generator variants as well as RS800, RS800A, RSS800A, RS800H, and RS800V roller models.
• Correct Grip Length for Original Assemblies — The 5/8-inch length is sized for the specific stack thickness found in these assemblies, preventing under-engagement or bottoming out in blind holes.
• Hex Head Drive for Positive Torquing — The hex head profile accepts standard wrenches and sockets, allowing fasteners to be driven to the correct torque without cam-out or rounding risk.

A hex head machine screw with an integrated flat washer is a structural fastener used to secure panels, brackets, covers, and housings throughout equipment assemblies. The flat washer face spreads the clamping load over a wider area than a bare screw head, which is especially important on thinner gauge panels or when fastening into softer substrates. When a fastener of the wrong thread pitch, length, or head style is used as a substitute, it can strip threads, leave components loose, or allow covers and guards to work free under vibration — making exact part number replacement the only reliable service option.
