Key Features
- Grade 5 Tensile Strength — Meets SAE Grade 5 standards for medium-strength structural fastening, providing the load-bearing capacity required in roller assembly joints.
- Correct Thread Specification — 1/2"-13 UNC (coarse) thread pitch matches the threaded receivers on the target roller assemblies for a clean, full-engagement installation.
- Exact OEM Length — At 2-1/4" length, this bolt matches the original design clearance and clamping requirements without shimming or substitution.
- Broad Roller Compatibility — Confirmed fitment for AR13HC, AR13H, AR13HA/HAR, AR13D, and R2000H Multiquip ride-on roller models.
- Genuine Multiquip OEM Part — Supplied as an authentic OEM component, ensuring the bolt's material grade, coating, and dimensions align with Multiquip's original engineering requirements for these machines.
A fastener of the correct grade, thread, and length is critical to the structural integrity of any assembly point on a ride-on roller. Grade 5 bolts are specified where joints must withstand significant vibration and dynamic loading — conditions that are standard operating reality on asphalt compaction equipment. Using an incorrect grade or length can result in under-torqued joints, fastener fatigue, or component misalignment, all of which can compromise machine operation and operator safety. Replacing a worn or damaged bolt with the correct OEM-spec Multiquip 509165 restores the joint to its original engineered condition.
