Bush Hog Bolt 1/2×1-1/4 Grade 5 OEM #44094BH

Keep your Bush Hog rotary cutter’s deck and baffle hardware securely fastened with this Genuine OEM 1/2″ x 1-1/4″ Grade 5 Capscrew (Part #44094BH). Confirmed in the official Bush Hog 3514/13514 rotary cutter parts manual as the Capscrew 1/2″ x 1-1/4″ Grade 5, used in a quantity of 12 per machine to secure the left-hand and right-hand baffle assemblies to the rotary cutter deck — this factory-correct fastener is precision-manufactured to exact Bush Hog specifications, delivering the correct thread engagement, clamping force, and Grade 5 tensile strength required for dependable baffle and deck structural integrity through demanding mowing and cutting operations.

Bolt Specifications:

• Thread Size: 1/2″-13 UNC (Unified National Coarse)
• Length: 1-1/4″ (1.25″)
• Grade: Grade 5 — heat-treated medium-carbon steel
• Type: Capscrew (Hex Head Cap Screw)
• Quantity per Machine (3514/13514): 12

Why Grade 5 OEM Fasteners Matter:
Rotary cutter deck and baffle hardware operates under constant vibration, impact loads from cutting debris, and the full dynamic stresses of high-speed PTO-driven operation. Grade 5 designation means this capscrew is heat-treated to a minimum tensile strength of 120,000 PSI — providing significantly greater resistance to vibration loosening, fatigue, and shear than common hardware store Grade 2 fasteners. Using incorrect grade, length, or thread specification hardware in these structural positions creates a risk of fastener failure, baffle shift, and deck hardware damage. Always replace with the correct genuine OEM Grade 5 capscrew.

This capscrew is used together with 1/2″ flat washers (#15916), 1/2″ lockwashers (#15806), and 1/2″ hex nuts (#15554) in the baffle-to-deck fastener assembly — always replace the complete fastener set for proper clamping and vibration resistance.

Signs These Capscrews Need Replacement:

• Visible thread stripping, deformation, corrosion, or cracking of the bolt shank
• Fastener unable to achieve or maintain proper torque specification
• Rounded hex head making installation or removal difficult
• Fastener backing off or loosening during normal mowing operation
• Baffle hardware loose, shifting, or damaged — inspect and replace all fasteners
• Routine deck service, baffle removal, or deck hardware inspection

Key Features:

• Genuine Bush Hog OEM part — not aftermarket or generic hardware
• 1/2″-13 UNC x 1-1/4″ — factory-correct thread and length specification
• Grade 5 heat-treated steel — superior vibration resistance, tensile strength, and fatigue life vs. Grade 2
• Correct fastener for baffle-to-deck structural assembly on compatible Bush Hog rotary cutters
• Manufactured to exact Bush Hog thread engagement and clamping force specifications
• Direct OEM replacement — installs to factory specification without modification

Compatibility:
This capscrew is confirmed for use on the Bush Hog 3514 and 13514 rotary cutter models and may be used across other Bush Hog rotary cutter and mower models that specify 1/2″ x 1-1/4″ Grade 5 hardware. Always confirm fitment using your Bush Hog model and serial number — found on the equipment identification plate — and cross-reference against your unit’s parts manual before ordering to verify the correct fastener specification for your specific assembly location.
