Key Features
- Genuine OEM Thread Specification — 10-32 thread pitch and 1/2 in. length match the exact fastener specification called out in the Multiquip parts manual for MP-series masonry saws.
- Hex Head Serrated Flange (HHST) Design — The serrated flange bearing surface resists loosening under vibration, which is critical in saw applications where continuous cutting cycles generate constant mechanical movement.
- Broad MP-Series Compatibility — Confirmed fitment across eleven MP masonry saw models, including the MP25E1, MP2H, MP275E3, MP2090HP, and MP1455HP series.
- Drop-In Installation — Correct thread form and drive type means the screw installs directly into existing threaded bosses without rethreading or modification.
- Maintains Structural Integrity — Using the specified OEM fastener prevents under-torque failures or stripped threads that can result from substituting an incorrect grade or thread pitch.
A hex head serrated flange screw — commonly abbreviated HHST — is a fastener that combines a standard hex drive head with an integrated serrated flange beneath it. The serrations bite into the mating surface as the fastener is tightened, creating mechanical resistance to loosening caused by vibration. On masonry saws like the MP series, fasteners are exposed to sustained vibration during blade operation, making the anti-loosening characteristic of this screw type functionally important. Using a replacement fastener that does not match the original thread specification or head type can compromise the clamped joint, leading to component movement, accelerated wear, or structural failure at the connection point.
