The Wacker Neuson Hexagonal Flange Head Screw is a genuine OEM hexagonal flange head screw designed for the LTN4Y and LTN5Y light tower series, as well as the APT4S and APT4T portable pump series. Sourced directly from Wacker Neuson, this fastener matches the original part in thread form, flange diameter, and head geometry — ensuring a correct, confident installation every time. It fits across a wide range of LTN and APT variants including cold weather and specialty configurations. If you're servicing a Wacker Neuson light tower or pump unit, using the correct OEM fastener like the protects the integrity of the assembly it secures.
Key Features
- Exact Thread and Flange Geometry — Genuine OEM specification means the hex flange profile seats flush and holds torque correctly without deforming the mating surface.
- Genuine Wacker Neuson OEM Part — Supplied directly through the Wacker Neuson parts network, ensuring the 5200019873 meets the same material and dimensional standards as the original hardware.
- Broad Series Compatibility — Fits the LTN4Y, LTN4Y RH, LTN5Y, LTN5Yp, LTN5Ypa, LTN5Ypk, and LTN5Yp HD light tower variants, plus APT4S and APT4T pump series including cold weather editions.
- Maintains Joint Clamping Force — A correctly spec'd flange head distributes load evenly across the joint face, preventing loosening under vibration — critical on mobile equipment like light towers and portable pumps.
- Drop-In Replacement — Replaces the original hardware position-for-position with no rework or modification to surrounding components required.
A hexagonal flange head screw combines a standard hex bolt with an integrated flange that acts as a built-in washer, spreading clamping load over a wider surface area. This design helps resist loosening caused by vibration — a common challenge on portable equipment that moves between job sites. When this type of fastener is missing, damaged, or substituted with an incorrect size, it can lead to joint failure, misalignment of attached components, or accelerated wear on the parts it holds in place. Using the correct OEM part number ensures the fastener performs as the original design intended.
