Husqvarna 542020367 Hex Head Cap Screw .3125-18 X 3.5 Grade 5 Zinc Plated

The Husqvarna 542020367 Hex Head Cap Screw.3125-18 X 3.5 Grade 5 Zinc Plated is a genuine OEM fastener designed for the MS610G masonry saw. This is a factory-specified hardware component, ensuring the correct thread pitch, grip length, grade rating, and zinc-plated finish match what Husqvarna engineered into the machine. DHS Equipment supplies this part to help keep your equipment running with the same hardware it left the factory with.

Key Features

• Grade 5 Tensile Strength — Built to the structural load and torque demands of masonry saw assemblies, where fastener grade directly affects joint integrity under vibration and cutting stress.
• Zinc-Plated Corrosion Resistance — The zinc plating provides a protective barrier against moisture and slurry exposure common in masonry cutting environments, extending service life at the joint.
• Exact Thread and Length Specification — The 5/16-18 UNC thread and 3.5-inch grip length match the original hardware specification exactly, so this screw seats and torques correctly without shimming or substitution.
• Direct OEM Replacement for MS610G — Sourced directly from Husqvarna as a genuine OEM component, this fastener is validated for use on the MS610G masonry saw.
• Correct Fit Protects Assembly Integrity — Using the right grade and dimension fastener prevents stripped threads, loosening under load, and misalignment of the components it secures.

A hex head cap screw is a structural fastener used to clamp and secure machine components — such as guards, housings, frames, and adjustment assemblies — under defined torque loads. On heavy-duty equipment like the MS610G masonry saw, fasteners are subject to significant vibration and mechanical stress during operation. Using the correct grade, thread, and length specification is essential: an undersized or incorrect-grade screw can back out, shear, or allow the connected components to shift, compromising both performance and operator safety. Replacing a damaged or missing screw with the genuine Husqvarna part ensures the joint is restored to its original clamping specification.
