The Multiquip 26385 is a genuine OEM Screw HHC 1/4-20 x 2-1/4 GRD8 designed for Whiteman ride-on power trowels and vibratory screed equipment. As a Grade 8 hex head cap screw, 26385 delivers the high-strength clamping force required by the demanding structural and mechanical fastening points found on STX55, HTX44, and WSHE-A series machines. Sourced directly from Multiquip, this screw matches the exact thread pitch, shank length, and tensile rating specified for these applications. Confirm your model — STX55Y6, STX55J6, HTX44K5, or HTX44K4 — before ordering to ensure a direct fit.
Key Features
- Grade 8 Tensile Strength — Meets the high-load fastening demands of ride-on trowel and vibratory screed assemblies, where under-spec hardware can lead to joint failure under vibration.
- Genuine OEM Specification — Manufactured to Multiquip's exact thread form (1/4-20 UNC), length (2-1/4 in.), and hardness grade, so the fastener performs as engineered in its original application.
- Direct Drop-In Installation — Standard hex head cap screw profile accepts common 7/16 in. wrenches and sockets, fitting existing threaded bores without thread chasing or rework.
- Broad Model Coverage — Confirmed fitment across STX55Y6, STX55J6, HTX44K5, HTX44K4, and WSHE-A series equipment, covering multiple Whiteman hydrostatic trowel and truss screed configurations.
- Vibration-Resistant Clamping — Grade 8 hardness resists fastener fatigue and loosening in high-cycle vibration environments typical of troweling and screeding operations.
A hex head cap screw (HHC) is a fully threaded or partially threaded fastener used to clamp two or more components together through a tapped bore or with a nut. In ride-on trowels and vibratory screeds, high-grade cap screws like this 1/4-20 x 2-1/4 GRD8 secure critical structural assemblies — including guards, frames, and drive components — that are subjected to continuous vibration and operational stress. Using a fastener of the correct thread, length, and grade is essential; substituting a lower-grade screw can result in fastener stretch, loosening, or shear failure, compromising both machine integrity and operator safety.
