Key Features

• Genuine OEM Fastener Grade — Manufactured to Husqvarna's precise thread specification and material hardness, delivering the correct clamping force and corrosion resistance expected of a factory-original cap nut.
• Direct Hardware Match — Engineered to thread directly onto the factory stud or bolt without rework, maintaining proper torque retention and flush seating against the mating surface.
• Broad WS-Series and Floor Saw Coverage — Fits the FS700E floor saw alongside a full range of WS-series wall saws, including the WS440, WS440HF, WS442, WS460, WS462, WS463, WS482, and WS482HF.
• Structural Integrity Under Load — A correctly seated cap nut keeps critical assemblies firmly secured during high-vibration cutting operations; a worn or cross-threaded fastener risks component loosening and unplanned stoppages.
• Operator Safety Assurance — On wall saws and floor saws, fastener integrity is directly tied to blade guard positioning and track or guide alignment — using the correct OEM-grade hardware maintains the secure assembly these machines require.

A cap nut is a closed-end fastener that threads onto a bolt or stud to secure two or more components together while covering and protecting the exposed thread end from damage, debris, and corrosion. On heavy-duty cutting equipment like wall saws and floor saws, cap nuts are used throughout the machine to hold assemblies, guards, and structural components firmly in place under the continuous vibration of diamond-blade cutting. When a cap nut strips, cracks, or loosens, the assembly it secures can shift or come free, compromising both cutting accuracy and operator safety.
