The Multiquip EM510717 1/2 NC x 1-3/4 Bolt is a genuine OEM fastener designed for use across AR14H asphalt rollers, WBH series power buggies, and LS series concrete pumps. As a factory-original component, it meets the exact thread specification and dimensional tolerances required for proper assembly and clamping force on these machines. Compatible models include the AR14H, WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, WBH-21EFP, WBH21EPA, LS-40, LS40D, LS40TD, LS50TD, LS60TD, LS400, LS450, LS500, LS600, and LS600P. Sourcing the correct OEM bolt ensures structural integrity and keeps your equipment operating to the manufacturer's designed assembly spec.
Key Features
- Genuine OEM Thread Accuracy — Manufactured to exact 1/2 NC x 1-3/4 inch specifications, ensuring correct engagement depth and clamping load at every fastener location.
- Direct-Fit Replacement — Threads seat cleanly into existing tapped holes and mating hardware without reworking the joint — install straight from the box.
- Broad Cross-Family Fitment — A single verified part number covers AR14H rollers, WBH-16 and WBH-21 power buggy variants, and the full LS40 through LS600 concrete pump lineup.
- Structural Integrity at Critical Joints — Using a correctly spec'd fastener maintains designed clamping force at structural and mechanical attachment points, preventing joint loosening under vibration and load cycles.
- Torque-Ready Hardware — OEM grade material ensures the bolt will hold rated torque values without galling or fastener yield during installation and service.
A bolt of this grade and dimension serves as a structural fastener at assembly joints throughout rollers, power buggies, and concrete pump frames and drive components. Correct thread form and fastener length are critical — an undersized or off-spec bolt can fail to develop the clamping force needed to keep joints secure under the vibration and load these machines generate in daily use. Over time, a worn or incorrect fastener can allow joint movement, accelerating wear on surrounding components and creating the potential for mechanical failure at a fastened connection.
