The Multiquip 12371 is a genuine OEM Hex Head Cap Screw 1/2-20 x 2 Gr 8 designed for AR13HA/HAR, AR13H, and AR13HC asphalt ride-on rollers. As a direct Multiquip OEM part, 12371 meets the exact grade and dimensional specifications called out in the original equipment design, ensuring a proper seating fit without the guesswork of sourcing a substitute. This screw is verified for use across the AR13 roller series, making it straightforward to confirm compatibility before you order. Keep a spare on hand and you are ready to get your roller back in service without delays sourcing hardware.
Key Features
- Grade 8 Strength Rating — Manufactured to Grade 8 specification, delivering the high tensile strength required for structural and drivetrain fastener applications on heavy compaction equipment.
- Exact 1/2-20 x 2 Thread and Length Specification — Matches the original thread pitch, diameter, and length exactly, so the fastener engages correctly without rework to mating components.
- Genuine OEM Sourcing — Sourced directly through Multiquip, this part carries the same material and dimensional standards as the hardware installed at the factory on AR13 series rollers.
- Confirmed AR13 Series Fitment — Verified for AR13HA/HAR, AR13H, and AR13HC ride-on asphalt rollers, so you can order with confidence knowing this is the correct hardware for your machine.
- Prevents Fastener Failure Under Load — Using an under-spec or incorrect-grade screw in a high-load application risks joint loosening or fastener shear; the correct Grade 8 rating maintains clamp force through sustained vibration and rolling load cycles.
A hex head cap screw is a threaded fastener used to clamp or secure structural components together, relying on its tensile strength and thread engagement to maintain a tight, load-bearing joint. On ride-on asphalt rollers like the AR13 series, fasteners in critical assemblies are subjected to continuous vibration, impact, and mechanical stress, which makes using the correct grade and size essential to maintaining structural integrity. A worn, stripped, or incorrect-grade screw can allow joint movement, accelerate component wear, and ultimately lead to assembly failure during operation.
