Part # 91000 – SH BOLT HX 1/2X1-5/8 (7/16-14)

SH BOLT HX 1/2X1-5/8 (7/16-14)

Western Part # 91000 is a Shoulder Bolt with a Hex Head, measuring 1/2 inch in shoulder diameter and 1-5/8 inches in shoulder length. It features 7/16-14 UNC (Unified National Coarse) threads on the end. This specialized bolt is designed for applications requiring a precise pivot point or a controlled spacing between components, while also providing the robust clamping force of a bolt.

The “shoulder bolt” characteristic means it has an unthreaded, precision-ground cylindrical shaft (the shoulder) with a larger diameter (1/2 inch) than its threaded portion (7/16-14). This shoulder acts as a bearing surface or a spacer, allowing a component to rotate freely on the bolt or maintaining a specific gap, while the threaded end secures the assembly. The 1-5/8 inch shoulder length dictates the thickness of the material or components it can precisely position. The hex head allows for easy tightening with a standard wrench or socket.

In Western Snow Plow applications, a shoulder bolt like Part # 91000 is used in critical pivot points, linkages, or precise spacing requirements where both strength and controlled movement are essential. This could include:

• Pivot points for movable assemblies: Allowing components to articulate smoothly.
• Mounting points where precise spacing is needed: Preventing over-compression or misalignment.
• Linkages within the plow’s trip mechanism or angling system: Ensuring correct geometry and operation.

Constructed from high-strength material, this bolt is designed to withstand the shear forces, rotational stress, and harsh conditions of snow plowing. Its precise dimensions ensure proper fit and function, contributing to the longevity and reliable operation of your plow. Always refer to your specific Western Plow model’s documentation and assembly diagrams to confirm compatibility with Part # 91000 and to follow proper installation procedures, including any required lubrication or torque specifications.
