The Multiquip 503117 is a genuine OEM Bolt 3/8 NC x 3 G5 designed for a wide range of Essick mixer, Whiteman mixer, and RAMMAX roller models including EM120, EM70, EM90, WM120PH, WM120SH, WM63, WM70, WM90, RW1404, and RW1504HF series equipment. As a direct OEM replacement, 503117 is manufactured to the same standards as the original hardware, ensuring correct thread engagement and clamping load across every application it supports. DHS Equipment stocks this fastener as part of a complete inventory of genuine Multiquip OEM parts, so you can order with confidence knowing you are receiving the correct component.
Key Features
- Grade 5 Fastener Strength — G5 rating delivers the tensile and yield strength required for structural and mechanical fastening on mixer and roller assemblies.
- Correct Thread Specification — 3/8 NC (National Coarse) thread form matches OEM threaded bosses and hardware exactly, allowing hand-tight seating before torquing without cross-threading risk.
- Broad Multiquip Fitment — Confirmed for EM120, EM70, EM90, WM63, WM70, WM90, WM120 series mixers and RW1404 and RW1504HF RAMMAX rollers.
- Genuine OEM Part — Sourced directly from Multiquip, 503117 meets the same material and dimensional spec as the hardware installed at the factory — no guesswork on grade or sizing.
- Consistent Torque Retention — Proper bolt grade and length ensure fastener stretch and clamping force stay within spec under vibration, which is critical on mixer drums and roller frames exposed to continuous operating loads.
A structural fastener like the Bolt 3/8 NC x 3 G5 is used throughout mixer frames, drum mounting assemblies, and roller structural joints to clamp components together under controlled tension. The Grade 5 designation means the bolt is engineered to resist loosening and fatigue under the cyclic vibration that concrete mixers and compaction rollers generate during normal operation. When a bolt of the wrong grade, length, or thread pitch is substituted, it can lead to under-clamping, accelerated wear on mating surfaces, or fastener failure — all of which compromise the integrity of the assembly it secures.
