The Multiquip 513489 is a genuine OEM Allen Head Screw 1/4"-20 x 3/8" designed for R2000H and AR13D rollers and WBH-21EF and WBH-21EFP power buggies. As a direct OEM replacement, this fastener is manufactured to the same thread specification and dimensional tolerances as the original hardware installed at the factory. Sourced directly through Multiquip's authorized parts network, 513489 ensures correct engagement depth and holding strength in every application it serves. If you're restoring a machine to full operating condition, starting with the correct OEM fastener is the right call.
Key Features
- Correct Thread Specification: — Cut to 1/4"-20 thread pitch and 3/8" length, matching the original fastener spec for secure, consistent clamping force.
- OEM Hardness and Material Grade: — Manufactured to the same material grade as the original, ensuring the screw won't strip, shear, or back out under operational vibration.
- Hex Socket Drive: — Allen head configuration allows for precise torque application with a standard hex key in tight or recessed mounting locations.
- Broad Fitment Across Equipment Types: — Compatible with R2000H and AR13D rollers as well as WBH-21EF and WBH-21EFP power buggies, making it a useful fastener to keep on hand across multiple Multiquip machines.
- Drop-In Replacement: — Threads directly into existing tapped holes with no chasing or rework required, keeping your service time short and your machine back in operation faster.
An Allen head screw — also called a socket head cap screw — uses an internal hex recess to accept a hex key or Allen driver, allowing the fastener to be tightened or removed in confined spaces where a standard hex bolt head would not fit. The 1/4"-20 designation refers to a 1/4-inch nominal diameter with 20 threads per inch, a common coarse-thread standard used widely in equipment assembly for its balance of holding strength and ease of installation. When a fastener of this type loosens, strips, or is lost during service, replacing it with the correct OEM specification screw is essential — an undersized or incorrect-grade substitute can work loose under vibration or fail to clamp mating components securely, leading to accelerated wear or misalignment of the assembly it anchors.
