Multiquip 30119 Screw 1/4-20 x 7/8 Inch Industrial Hex

The Multiquip 30119 is a genuine OEM 1/4-20 x 7/8 Inch Industrial Hex Screw designed for a wide range of Multiquip and Whiteman equipment including walk-behind power trowels, ride-on roller screeds, and towable light towers. As a factory-sourced fastener, it meets the exact thread specification, head geometry, and material grade called out in the original equipment build. This screw is confirmed for use across the CA4HM, CA4HC, CA5BC, BS90C, BH11C, BH90C, HDA-Series, JS60C, JH90C, JH55C, B46, J36-M30 Series, J3036H55, WRSPUDF, WRS5200, WRS5200DFPU, LT6KV, and LT6K models. When fasteners wear, strip, or go missing during service, replacing them with the correct OEM specification keeps assemblies torqued properly and components securely in place.

Key Features

• Exact Thread and Head Specification — 1/4-20 thread pitch and 7/8-inch length match the original fastener spec, so the screw seats and torques correctly without thread damage or under-engagement.
• Genuine OEM Sourcing — Factory-original fastener manufactured to the same material grade and dimensional tolerance as the screw installed at the Multiquip production line.
• Broad Cross-Model Compatibility — Confirmed fit across Whiteman walk-behind power trowels (CA, B, J, HDA, BS, BH, JS, JH series), Whiteman ride-on roller screeds (WRS5200, WRSPUDF, WRS5200DFPU), and towable light towers (LT6K, LT6KV).
• Secure Assembly Integrity — The correct hex head drive style ensures proper torque application during installation, preventing fastener rounding or loosening under operational vibration.
• Service and Rebuild Ready — A straightforward drop-in replacement for stripped, corroded, or missing hardware encountered during routine maintenance, blade changes, or panel removal.

A hex head machine screw like the Multiquip 30119 serves as a structural fastener that secures panels, guards, brackets, and assemblies throughout the machine. Using a fastener with the correct thread form and length ensures full thread engagement in the mating hole or nut, which is critical for maintaining clamping force under the vibration loads that trowels and screeds generate during operation. A screw with the wrong thread pitch, length, or head style can strip out the receiving thread, fail to clamp adequately, or prevent proper reassembly after service — all of which can lead to loose components and unplanned downtime on the pour.
