Murray 1728976sm Shoulder Bolt 5/16-18

Product Description

The MURRAY 1728976sm is a 5/16-18 shoulder bolt used as a structural fastener in Murray lawn and garden equipment. Shoulder bolts feature a precise unthreaded shank between the head and the threaded section, allowing controlled movement or pivot at the joint. This design is common in mower deck linkages, blade engagement mechanisms, and other assemblies where a rotating or sliding connection is required. Installation is typically performed by small-engine equipment technicians or experienced service dealers during routine deck maintenance or component replacement.

This shoulder bolt is intended for use in Murray lawn and garden equipment assemblies. It is suited to residential mower applications where OEM fastener dimensions are required to maintain correct joint clearance and function. Using a correctly sized shoulder bolt ensures that linked components pivot freely without excess play, which is critical to safe and consistent cutting performance.

Key Features

• 5/16-18 thread specification for precise fitment in Murray OEM assemblies
• Shoulder design provides a controlled unthreaded bearing surface for pivot or sliding joints
• OEM replacement part sourced directly from Murray
• Suited for deck linkage, engagement lever, and similar mechanical connections

Compatibility

Installation Notes

Shoulder bolt installation on outdoor power equipment should be performed by a qualified small-engine technician. Disconnect the spark plug wire and allow all moving parts to come to a complete stop before beginning any fastener service. Use the appropriate wrench or socket for the bolt head size and do not overtighten, as shoulder bolts rely on controlled clamping to function correctly at pivot points. Consult the equipment service manual for the correct torque range and assembly sequence.
