Wacker Neuson 5100047678 Screw Triple 4x16 10.9 A3K

The Wacker Neuson Screw Triple 4x16 10.9 A3K is a genuine OEM fastener designed for the BS62-2lb/16 rammer, FUH35/2/42, FUH70/4/42, FUH70/4/42s, FUH70/6/42s, FUH70/4/42p CH, and KMAT rammer series. Sourced directly from Wacker Neuson, this triple screw meets the exact grade 10.9 tensile and dimensional specification called out in the original build. If you're servicing one of the listed rammer models, part number is the correct OEM replacement to keep critical assemblies properly torqued and secured.

Key Features

• Grade 10.9 Tensile Strength — High-strength property class 10.9 rating delivers the clamping force these rammer assemblies demand under repeated impact loading.
• Genuine OEM Part — Manufactured to Wacker Neuson's exact thread form, length, and head specification — threads engage and seat exactly as the original build intended.
• Broad Rammer Compatibility — Fits BS62-2lb/16, FUH35/2/42, FUH70/4/42, FUH70/4/42s, FUH70/6/42s, FUH70/4/42p CH, and KMAT rammer models in a single part number.
• Consistent Joint Integrity — A correctly torqued, properly graded screw keeps fastened components from loosening during the high-frequency vibration cycles rammers generate — preventing premature wear and structural shifting.
• Direct OEM Sourcing — Ordered from the Wacker Neuson parts network, so you receive the same hardware that left the factory with the machine.

A triple screw like the 5100047678 is a high-strength threaded fastener used to clamp and secure structural or mechanical components within the rammer assembly. At grade 10.9, it is engineered to withstand significant tensile and shear loads without stretching or loosening — critical in compaction equipment that operates under constant, heavy vibration. When a fastener of this type fails, becomes over-torqued, or is replaced with an incorrect grade, joint clamping force is lost, leading to component movement, accelerated wear, and potential assembly failure.
