Description
05901840 – Ariens / Gravely Button Head Socket Cap Screw (5/16"-18 × 1.00, ZCC)
The Ariens / Gravely 05901840 is a genuine OEM button head socket cap screw (SHCS-BTN) with a 5/16"-18 thread and 1.00" length. This low-profile, rounded button head Allen/hex-drive screw is commonly used where a standard hex bolt would interfere with moving parts, covers, or seat hardware—especially on seat/seat support assemblies across many Ariens® zero-turn models.
The ZCC corrosion-resistant coating helps protect the fastener from rust and outdoor exposure, making it a dependable replacement for original factory hardware.
