As a direct OEM replacement, this spring is manufactured to the same specification as the original component, ensuring a correct drop-in fit with no guesswork on compatibility. Sourced directly through authorized Multiquip supply channels, the part is the right call when you need a like-for-like restoration of your saw's locking pin mechanism. DHS Equipment stocks this part ready to ship so your saw gets back to cutting without unnecessary delays.
Key Features
- Genuine OEM Spring Tension Rating — manufactured to the original tension specification, so the locking pin engages and releases with the same resistance and snap as the factory-installed component.
- Direct Drop-In Replacement — engineered to seat into the same pin housing as the original, with matching geometry for correct retention and release travel.
- Broad Masonry Saw Compatibility — fits the MS18E, MS20H, MS20E, MS30H, MS30E, MS18H5.5, and MS18H8, covering a wide range of Multiquip masonry saw configurations.
- Restores Positive Pin Engagement — a fatigued or broken locking pin spring allows the pin to back out under vibration, causing blade guard or depth stop misalignment during cuts; replacing it restores consistent, positive lock-up.
- Operator Safety Relevance — the locking pin secures adjustable guards and blade depth settings; a correctly tensioned spring is essential to keeping those adjustments locked under the vibration loads generated during masonry cutting.
The locking pin spring provides the return force that seats and retains the locking pin in its engaged position on the masonry saw. It works against the operator's pull when releasing an adjustment and snaps the pin back into the detent once the desired setting is reached, holding guards, fences, or depth stops firmly in place during operation. When the spring fatigues, stretches, or breaks, the pin can drift or fail to fully engage, leaving adjustable components free to shift mid-cut and compromising both cut accuracy and operator safety.
