Multiquip 915316 Screw HHC 5/8-11 x 3 LH GR8

The Multiquip 915316 is a genuine OEM Screw HHC 5/8-11 x 3 LH GR8 designed for SP, PS, and CS series pavement saws and flat saws. As a direct Multiquip OEM part, 915316 is manufactured to the exact thread specification, grade, and left-hand orientation required by these machines. Fitment covers a wide range of models including SP303516, SP303520, SP303526, SP303530, SP403016, SP403020, SP403026, SP403030, SP605716, SP605720, SP605726, SP605730, SP605736, SP605736, SP706016, SP706020, SP706026, SP706030, SP706036, PS403016, PS403020, PS403026, PS403030, PS706016, PS706020, PS706026, PS706030, PS706036, SP4, SP6457, CS403016, CS403020, CS403026, CS403030, CS706016, CS706020, CS706026, CS706030, and CS706036. Sourcing the correct grade and hand orientation is critical on pavement saw applications — this fastener delivers exactly that.

Key Features

• Left-Hand Thread, Grade 8 Construction — The LH thread pattern and GR8 rating are engineered specifically for high-torque, high-vibration pavement saw environments where standard right-hand fasteners would loosen under load.
• Genuine OEM Part — Supplied directly by Multiquip, this screw meets the exact dimensional, thread-pitch, and hardness specifications called out in the original machine design — no substitution required.
• Hex Head Cap Screw (HHC) Profile — The standard hex head format allows installation and removal with common hand and impact tooling, simplifying blade changes and drivetrain service in the field.
• Broad SP, PS, and CS Series Compatibility — A single part number covers dozens of SP, PS, and CS pavement and flat saw configurations, making 915316 a practical stocking item for operators running multiple saw models.
• Critical Retention Function — A worn, stripped, or incorrect-hand fastener in this position can allow blade arbor or drive components to work loose during cutting, leading to blade slippage or component damage. Using the correct GR8 LH screw maintains secure clamping throughout the cut.

A hex head cap screw in a left-hand thread configuration is used in rotating assemblies where the natural direction of shaft or blade rotation would otherwise cause a conventional right-hand fastener to back out over time. On pavement saws, this type of fastener is commonly found securing blade arbor hardware or drive components that spin in a direction that would loosen standard threads. Grade 8 hardness ensures the fastener can withstand the clamping loads and vibration stresses generated during concrete and asphalt cutting. Using a screw of the wrong thread hand, grade, or size in this position risks fastener back-out, loss of blade retention, and potential damage to the cutting assembly.
