The Multiquip 56080 Hex Bolt 12X35 8.8 Din 7991 is a genuine OEM fastener designed for the RW1404MR and RW1403HF RAMMAX walk-behind rollers. As a direct OEM replacement, part 56080 meets the original engineering specification for grade, thread pitch, and dimensions — ensuring a secure, properly torqued connection right out of the box. This bolt is confirmed to fit RW1403HF, RW1404MR, and RW1404MR units with serial numbers 326075 and up. Sourcing the correct OEM hardware is critical on roller equipment where fastener grade and sizing directly affect structural integrity and safe operation.
Key Features
- Grade 8.8 Rated Fastener — Meets DIN 7991 specification for tensile strength and load-bearing capacity, appropriate for structural and mechanical fastening on roller equipment.
- Exact OEM Hardware Match — 12mm diameter, 35mm length, and DIN 7991 hex socket head profile match the original bolt position without any modification to mounting hardware or hardware seats.
- Confirmed Fitment — Verified for RW1403HF, RW1404MR, and RW1404MR (S/N 326075 and up) RAMMAX walk-behind rollers.
- Structural Connection Integrity — A correctly spec'd bolt at the correct torque keeps critical assemblies properly clamped; an incorrect grade or size can lead to loosening, component movement, or fastener failure under vibratory load.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, so the grade marking, thread form, and head geometry are exactly what the machine was built with.
A hex bolt in a vibratory roller application does more than hold two parts together — it maintains the clamped load needed to resist the constant vibration and dynamic forces generated during compaction passes. On RAMMAX rollers, fasteners in drive, frame, and drum assemblies are subject to cyclical stress that can expose any mismatch in grade, thread pitch, or length. Using the correct DIN 7991 Grade 8.8 fastener ensures the joint behaves as the engineers intended. A worn, incorrect, or under-grade bolt in these positions can back out or fail, leading to component misalignment or more serious mechanical damage.
