Bomag 05570012 Socket Head Cap Screw

The Bomag 05570012 Socket Head Cap Screw is a genuine OEM fastener designed for an extensive range of Bomag single drum rollers, tandem rollers, walk-behind rollers, and recycler/stabilizer machines, including the BW 213 DH-4, BW 216 PDH-4, BW 226 DH-4, BW 120 AD-4, BW 202 AD-50, MPH 364-2, and RS 360 TIER-4F, among many others. Sourced directly from Bomag, this screw matches the exact geometry, thread specification, and head profile called out in the original equipment design. This genuine OEM component installs directly in place of the factory original with no guesswork, ensuring the connection point performs exactly as intended across the full service life of the machine.

Key Features

• Genuine OEM Thread and Head Geometry — manufactured to Bomag's own dimensional standards, ensuring the hex socket engages correctly and torque is transferred without fastener deformation or rounding
• Direct Factory Replacement — part number 05570012 matches the original screw specification exactly, dropping into the designed boss or bore without adjustment or re-drilling
• Broad Roller and Stabilizer Coverage — confirmed fit across Bomag BW single drum rollers, tandem rollers, the BW 900-2 walk-behind roller, and MPH 364-2 and RS 360 TIER-4F recycler/stabilizer machines
• Structural Joint Integrity — a correctly specified cap screw maintains clamping force at critical assemblies; an undersized or incorrect fastener can back out under vibration, leading to component misalignment or damage
• Vibration-Resistant Fastening — the socket head cap screw profile resists loosening in high-vibration compaction environments better than standard hex-head alternatives, keeping structural joints secure through demanding operating cycles

A socket head cap screw is a precision fastener with a cylindrical head and an internal hex drive, used wherever a low-profile, high-clamping-force connection is required in tight or recessed spaces. On compaction rollers and stabilizers, these screws secure major structural and mechanical assemblies that are subject to continuous vibration and dynamic load — conditions that demand consistent clamping force over time. When a socket head cap screw wears, strips, or is replaced with an incorrect specification, the affected joint can lose preload, allowing movement that accelerates wear on surrounding components and compromises the reliability of the assembly.
