Multiquip 1313 Flat Head Socket Cap Screw 3/8-24 x 3/4 Plain

The Multiquip 1313 is a genuine OEM Flat Head Socket Cap Screw 3/8-24 x 3/4 Plain designed for a wide range of Multiquip and Whiteman equipment including HHN, HTN, HDA, JWN, and FS-Series models. As a direct OEM replacement, part 1313 ensures the correct thread pitch, head geometry, and plain finish specified by Multiquip for these applications. This screw is confirmed to fit across ride-on power trowels, walk-behind power trowels, and flex-shaft concrete vibrator series. Sourcing the correct fastener matters — an improperly spec'd screw can compromise the structural integrity of the assembly it secures.

Key Features

• Correct Thread Specification — 3/8-24 fine-thread pitch matches the OEM-specified fastener engagement for a secure, torque-compliant installation.
• Flat Head Socket Cap Profile — Countersunk head design sits flush with mating surfaces, maintaining proper clearance in tight assembly areas on trowel and vibrator housings.
• Plain Finish — Uncoated steel finish matches the original specification, suitable for the controlled environments these assemblies operate in.
• Broad Fitment Coverage — Fits HHN, HTN, HDA, JWN, FS-Series, and additional Whiteman ride-on and walk-behind power trowel models.
• Genuine OEM Part — Manufactured to Multiquip's exact dimensional standards, eliminating the guesswork of sourcing a generic substitute that may not meet thread engagement or head tolerancing requirements.

A flat head socket cap screw (FHSC) is a precision fastener engineered to seat flush within a countersunk hole, distributing clamping load evenly while keeping the mating surface clear of protruding hardware. In concrete trowel and vibrator assemblies, these screws are commonly used to secure guards, drive components, and structural panels where a raised fastener head would interfere with adjacent parts or operator safety. When a fastener of the wrong thread pitch, length, or head angle is installed, it can strip threads, loosen under vibration, or prevent proper component seating — leading to premature wear or mechanical failure in demanding concrete finishing applications.
