The Multiquip EM25301 is a genuine OEM HHC Screw 3/8-16 x 1 Grade 8 designed for ST-45HRM, ST-70, and FS3SP series equipment. As a direct Multiquip OEM part, EM25301 meets the original engineering specifications for thread pitch, head geometry, and tensile strength. Sourced from DHS Equipment, this fastener is verified for compatibility with the submersible pump and concrete saw applications listed above. Confirm your model code before ordering to ensure a correct match.
Key Features
- Grade 8 Tensile Strength — High-strength Grade 8 rating delivers the clamping force and shear resistance required in demanding construction equipment applications.
- Exact Thread Specification — 3/8-16 thread pitch and 1-inch length match the original fastener profile, allowing straightforward installation without rethreading or modification to mating components.
- Genuine OEM Part — Manufactured to Multiquip's original specifications, ensuring correct head dimensions, drive type, and material grade for the intended mounting points.
- Confirmed Fitment — Verified for use on ST-45HRM and ST-70 submersible pumps and the FS3SP concrete saw; always cross-reference your model code and service manual torque spec before installation.
- Structural Integrity at the Joint — A correctly graded fastener maintains proper preload at critical connection points; an under-spec or worn bolt can lead to loosening, misalignment, or component separation under vibration and load.
A hex head cap screw is a precision fastener used to secure structural and mechanical connections within equipment assemblies. The Grade 8 classification indicates a higher carbon steel composition with heat treatment, giving the bolt the tensile and proof load ratings needed to withstand the vibration, hydraulic pressure, and mechanical stress common in pump and saw applications. When a fastener of the wrong grade, thread pitch, or length is used, joint preload is compromised, which can result in loosening during operation, accelerated wear on mating surfaces, or fastener failure at the worst possible moment.
