Key Features
- Correct Thread Specification — 1/4-20 x 3/4 thread form matches the original fastener exactly, ensuring proper clamping force and thread engagement in tapped housings and panels.
- Hex Washer Slotted Head Design — The integrated washer flange distributes load across the mating surface, while the slotted drive allows installation with a standard flat-head screwdriver or hex wrench where space is limited.
- Genuine OEM Quality — Manufactured to Multiquip's original hardware specification, meaning correct material grade and surface treatment for the fastener's intended application on ride-on trowel assemblies.
- Broad Trowel Family Compatibility — Fits HTN27K, HTN28K, HHN31V, HHN34TVD, JWN24HTCSL/HSCSL, and HTNS5S-2 ride-on power trowels, covering both the 6 ft light-duty and 8 ft heavy-duty Whiteman mechanical trowel lines.
- Prevents Loosening and Panel Shift — A correctly torqued, properly spec'd fastener keeps covers, guards, and components from shifting under the constant vibration generated during troweling operations.
A hex washer slotted screw is a multi-purpose machine fastener that combines a built-in washer flange beneath the head with a slotted drive recess. The washer flange spreads clamping load to protect softer mating surfaces and resist pull-through, while the hex washer profile also allows driving with a nut driver or socket for faster installation. On ride-on power trowels, fasteners like part 11819 secure panels, guards, and structural covers that are exposed to continuous vibration and mechanical stress. When these screws strip, back out, or are replaced with incorrect hardware, panels can loosen, components can shift, and the structural integrity of guarded areas can be compromised during operation.
