The Multiquip EMHS11 Piston Lock Screw ST80 HS-11 is a genuine OEM component designed for the ST80 pavement saw. Sourced directly from Multiquip, this screw is an exact match for the original hardware used in ST80 production, ensuring proper fit and secure installation without the guesswork of cross-referencing aftermarket alternatives. If you're servicing or rebuilding a ST80 and need to restore the piston locking assembly to proper spec, the part is the correct OEM-sourced replacement.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the same material and thread specification as the original screw, ensuring the piston lock engages and holds with the correct clamping force.
- Direct Drop-In Installation — Threaded dimensions and head profile match the ST80 piston lock assembly exactly, allowing straightforward installation with standard hand tools.
- Confirmed ST80 Fitment — Verified for use on the Multiquip ST80 pavement saw; reference model code ST80 when ordering to confirm compatibility.
- Maintains Piston Lock Integrity — A correctly torqued piston lock screw keeps internal components secured during saw operation; a worn or missing screw can allow unwanted movement and accelerate wear on surrounding parts.
- Fuel System and Blade Safety Relevance — On cutting equipment, a secure piston lock is critical during blade changes and servicing to prevent accidental engagement, supporting safe maintenance practices.
The piston lock screw on the ST80 pavement saw is responsible for securing the piston within the locking assembly, preventing unintended movement during operation or maintenance procedures. This small but critical fastener must maintain consistent clamping force — if it becomes stripped, loosened, or lost, the piston lock can fail to hold properly, creating a safety risk during blade servicing and the potential for internal component damage during cutting cycles. Replacing a worn or damaged screw with the correct OEM part, Multiquip EMHS11, restores the lock assembly to its intended operating condition.
