Key Features

• Genuine OEM Thread Specification — 3/8-16 thread pitch and 3-1/4 inch grip length match original hardware exactly, maintaining proper clamping force and torque values across all fastened joints.
• Hex Head Cap (HHC) Profile — The hex head cap design allows for standard wrench or socket installation, making removal and reinstallation straightforward during routine service or teardown.
• Broad Cross-Model Compatibility — Fits an extensive range of Multiquip and Whiteman walk-behind trowels, concrete saws, flat saws, and pavement saws including the J36, SP, FS, BH, JH, CS, and CC series.
• Structural Fastener Integrity — Using the correct grade and dimension of fastener prevents joint loosening, component misalignment, and accelerated wear on mating surfaces during high-vibration operation.
• Direct OEM Replacement — Part 1493 installs in place of the original screw with no modification to existing hardware, mounting points, or surrounding components.

A hex head cap screw is a structural fastener used to clamp and secure major components together — such as blade guards, housings, frames, and drive assemblies — on trowels and saws. The 3/8-16 designation refers to the screw's nominal diameter and thread count per inch, while 3-1/4 indicates the full grip length. Using a fastener with the wrong thread pitch or length can result in cross-threading, insufficient clamping depth, or joint failure under operational load. On high-vibration equipment like power trowels and concrete saws, maintaining the correct fastener specification at every connection point is essential to keeping assemblies secure and preventing premature wear or component separation.
