Multiquip 208 Screw FHSC 5/16"-18 x 3/4"

The Multiquip 208 is a genuine OEM Screw FHSC 5/16"-18 x 3/4" designed for a wide range of Multiquip power trowel, screed, saw, pump, and vibrator equipment. This flat-head socket cap screw is a direct OEM replacement sourced to exact thread and dimensional specifications, ensuring it seats and torques correctly every time. Compatible across an extensive lineup including STX, HTX, HDA, PRX, MD, LD, STR, and JWN series trowels, WSHE screed systems, SP118 flat saws, and select pump and vibrator models, part 208 covers one of the broadest fitment ranges in the Multiquip hardware catalog. Having the correct fastener on hand keeps critical assemblies properly secured and avoids delays waiting on hardware.

Key Features

• Genuine OEM Thread Specification — Manufactured to the exact 5/16"-18 UNC thread pitch and 3/4" length called out in Multiquip service documentation, so the screw engages mating threads without risk of cross-threading or under-torque.
• Flat-Head Socket Drive — The countersunk flat-head profile seats flush with mating surfaces, while the internal hex socket accepts a standard Allen/hex key for controlled installation in tight access areas common on trowel and screed assemblies.
• Broad Cross-Equipment Fitment — A single part number covers walk-behind and ride-on power trowels (STX, HTX, HDA, PRX, MD, LD, JWN, HTN, CA, BS, JS, J, B series), WSHE vibratory screeds, SP118 saws, and select vibrator and pump models.
• Correct Clamping Force for Structural Joints — Using the specified OEM fastener ensures designed clamping load is achieved at critical joints — substituting incorrect grade or length hardware risks joint loosening under vibration loads typical of concrete finishing equipment.
• Genuine Multiquip OEM Part — Supplied as an authentic Multiquip replacement, matching the original material grade and finish to resist corrosion and maintain holding strength across repeated service intervals.

A flat-head socket cap screw (FHSC) is a threaded fastener with a countersunk, conical head that sits flush with or below the surface of the mating component when fully installed. The internal hex socket drive allows precise torque application even in recessed or confined mounting locations frequently found on trowel blade guards, screed frames, and equipment housings. When a fastener of the wrong thread pitch, length, or head style is used, the joint can loosen prematurely under the continuous vibration loads these machines generate, leading to misalignment, component wear, or structural failure. Using the correct Multiquip 208 screw ensures the assembly performs as engineered throughout its service life.
