The Wacker Neuson Hexagonal Head Cap Screw is a genuine OEM fastener designed for LTN4Y and LTN5Y light tower series and APT4S and APT4T portable pump series equipment. Sourced directly from Wacker Neuson, this is the exact part specified for your machine — not an approximation. The covers an extensive range of configurations across both the LTN and APT product lines, including cold weather variants, surge brake, and electric brake models.
Key Features
- Genuine OEM Fastener Grade — Manufactured to Wacker Neuson's exact thread specification, head geometry, and tensile rating, so the fastener seats and torques correctly every time.
- Direct Bolt-In Replacement — Matches the original hardware dimensions for tool-free identification and drop-in installation with no rework to mating components.
- Broad Series Compatibility — Fits LTN4Y, LTN4Y RH, LTN5Y, LTN5Yp, LTN5Ypa, LTN5Ypk, LTN5Yp HD, and APT4S and APT4T pump series, including cold weather and voltage variants.
- Structural Integrity Where It Counts — A correct, properly torqued cap screw keeps critical assemblies secure under vibration and load; an incorrect or worn fastener risks loosening, misalignment, or component damage during operation.
- Authorized OEM Part — Part number 5200019921 is the Wacker Neuson-issued part number for this application, giving you full confidence that fitment and spec are verified at the source.
A hexagonal head cap screw is a threaded fastener used to clamp or secure two or more components together within a machine assembly. Its hex head allows a wrench or socket to apply precise torque, ensuring the joint holds firm under the vibration and mechanical stress common in light towers and portable pumps. When a cap screw stretches, strips, or is replaced with an incorrect substitute, the joint can work loose over time — leading to component movement, wear on mating surfaces, and potential failure of the assembly it holds together.
