The Multiquip M839020S Hex Flange Screw Str46Sp is a genuine OEM fastener designed for HTN27K and HTN28K Whiteman ride-on power trowels. As a direct Multiquip OEM part, M839020S is manufactured to the exact specification required for these machines, ensuring correct torque retention and a secure, flush-seating fit. This screw is compatible with both the HTN27K and HTN28K models, making it a straightforward stock item for crews running either unit. DHS Equipment supplies this part directly as an authorized Multiquip OEM distributor.
Key Features
- Genuine OEM Fastener Grade — manufactured to the exact thread pitch, shank diameter, and flange geometry specified by Multiquip for this application, not a generic hardware substitute.
- Integrated Flange Design — the built-in flange distributes clamping load evenly across the mating surface, eliminating the need for a separate washer and maintaining consistent clamp force.
- Direct Replacement for HTN27K and HTN28K — verified fitment for both Whiteman ride-on mechanical trowel models; installs in place of the original without modification.
- Maintains Structural Integrity — a correctly spec'd fastener keeps critical assemblies secured during trowel operation; an underspec or incorrect screw risks loosening under vibration and load cycling.
- Part Number M839020S for Accurate Ordering — cross-reference against your parts manual using M839020S to confirm the correct position before ordering.
A hex flange screw combines a standard hex-drive head with an integral flange that acts as a built-in washer, spreading the bearing load over a wider area than a plain bolt head. This design resists loosening under vibration — an important quality in ride-on trowel applications where the machine is subject to continuous oscillating forces during finishing passes. When a fastener of this type fails or goes missing, the assembly it secures can shift, wear unevenly, or come loose entirely, creating both a performance issue and a potential safety concern for the operator.
