The Wacker Neuson Socket Head Cap Screw is a genuine OEM fastener designed for the RD27-100 and RD27-120 series hydrostatic vibratory rollers and ride-on rollers. As a direct factory part, it meets the exact thread specification, head geometry, and material grade specified for these machines. This screw is confirmed to fit across multiple RD27 production variants, including the RD27 Pro Tandem Roller and RD27 Basic T4F models, making it the straightforward choice when servicing or reassembling these compaction units.
Key Features
- OEM Thread and Torque Integrity — Manufactured to the exact thread pitch and tensile grade specified by Wacker Neuson, ensuring consistent clamping force and resistance to loosening under machine vibration.
- Hex Socket Drive for Precise Installation — The internal hex socket head allows torque to be applied cleanly with an Allen key or hex bit, helping technicians achieve the correct fastening depth without damaging surrounding components.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 configurations across Hydrostatic Vibratory Roller, Ride-On Roller, Pro Tandem Roller, and Basic T4F variants.
- Vibration-Resistant Fastening — On a vibratory roller, fasteners are subjected to continuous cyclic loading; a correctly specified cap screw maintains joint integrity and prevents component shift during compaction passes.
- Sourced Direct from Wacker Neuson — Supplied as a genuine OEM part, so the part number, dimensions, and material spec align exactly with what left the factory — no guesswork on fitment.
A socket head cap screw is a precision fastener used to secure components in assemblies where a flush or recessed head profile is required and where controlled torque is critical. On vibratory compaction equipment like the RD27 series, fasteners must withstand sustained mechanical vibration without backing out or fatiguing, making correct specification essential. A worn, incorrect, or under-torqued cap screw can allow components to shift or separate, leading to accelerated wear or mechanical failure in the affected assembly.
