The Multiquip 9153 is a genuine OEM Hex Head Cap Screw 5/8-11 x 4 GRD 8 designed for Multiquip light towers and water trailers including the LT6KV, LT6K, WT5HP, and WT5C series. As a factory-sourced fastener, this screw meets the exact thread pitch, length, and grade specification required by the original equipment design. Sourcing the correct OEM fastener ensures that clamped joints maintain proper torque retention and structural integrity — critical wherever high-load connections are used in the field. DHS Equipment supplies this part direct, so you get the right component the first time.
Key Features
- Grade 8 Tensile Strength — Manufactured to SAE Grade 8 specification, delivering the high tensile and proof-load strength required at structural connection points on light towers and water trailer assemblies.
- Correct Thread Engagement — 5/8-11 UNC thread form and 4-inch length match the original tapped holes exactly, allowing full thread engagement without rework or shimming.
- Genuine OEM Sourced — Supplied as a factory Multiquip OEM part, ensuring the fastener material, heat treatment, and dimensional tolerances are consistent with the original build specification.
- Broad Series Compatibility — Confirmed fitment across LT6KV and LT6K towable light towers and WT5HP, WTE5HP, WT5HPSG, WT5C, WTE5C, and WT5CSG water trailer models.
- Structural Connection Reliability — A properly torqued Grade 8 fastener resists loosening under vibration and load cycling; an incorrect or under-spec screw risks joint movement, component misalignment, or fastener failure under working loads.
A hex head cap screw is a fully threaded or partially threaded fastener used to clamp two or more components together at a structural joint. The grade designation — Grade 8 in this case — defines the minimum tensile strength and hardness of the fastener, making it suitable for high-stress connections where a lower-grade screw could stretch or shear under load. On equipment like towable light towers and water trailers, these fasteners are commonly used at frame joints, mounting brackets, and hitch assemblies where maintaining clamping force through vibration and transport loads is essential. Using an incorrect grade or an incorrect length screw at these points can result in premature fastener fatigue, loss of preload, or joint movement that accelerates wear on surrounding components.
