The Multiquip 21316 is a genuine OEM Hex Head Cap Screw 5/8-18 x 3 designed for HTN27K and HTN28K Whiteman ride-on power trowels. As a factory-sourced fastener, this screw matches the exact thread pitch, grip length, and head specification called for in the original build — so it installs cleanly without reworking the joint. Sourced directly through Multiquip's OEM parts program, the 21316 is the correct replacement when inspecting, servicing, or rebuilding fastener hardware on these machines. Verify your model against the HTN27K and HTN28K fitment before ordering to ensure a direct swap.
Key Features
- Correct Thread and Length Specification — 5/8-18 thread pitch with a 3-inch grip length matches the OEM torque and clamping requirements for the fastened joint.
- Genuine OEM Part — Sourced through Multiquip's OEM supply chain, ensuring the fastener meets the material grade and dimensional standard specified for these trowels.
- Direct Replacement Hardware — Threads into the original tapped bore without modification, maintaining proper clamp load on the assembled component.
- Confirmed Fitment — Verified for HTN27K and HTN28K Whiteman ride-on mechanical trowels; reference part number 21316 when ordering.
- Structural Integrity Maintained — Using the correct grade and size fastener preserves the designed clamping force — an undersized or incorrect-thread screw can lead to joint loosening under the vibration loads typical of trowel operation.
A hex head cap screw is a precision-grade threaded fastener used to clamp and secure structural or mechanical components together on the machine. On ride-on power trowels like the HTN27K and HTN28K, fasteners at this size and thread specification are typically found in high-load connection points where consistent torque retention matters — such as drive or frame assemblies. When a screw of this type is stripped, under-torqued, or replaced with an incorrect specification, the joint can work loose under the continuous vibration of trowel operation, potentially affecting blade control and machine stability. Replacing with the correct OEM fastener restores the designed clamping load and keeps the assembly secure through normal service intervals.
