The Multiquip 3437 HHC Screw 5/16-18X4.0 GRD8 is a genuine OEM fastener designed for LT6K and LT6KV series towable light towers. As a Grade 8 hex head cap screw, it meets the tensile strength requirements specified by Multiquip for structural and mechanical connections on these units. Fitment is confirmed for the LT6K and LT6KV (60Hz) towable light tower models. Sourcing the correct OEM screw ensures the fastened joint performs as engineered and avoids the risk of fastener failure under load or vibration.
Key Features
- Grade 8 Tensile Strength — Heat-treated alloy steel construction meets the high-strength demands of structural fastener positions on light tower assemblies, where standard hardware grades are not an appropriate substitute.
- Exact Thread and Length Spec — 5/16-18 UNC thread form and 4.0-inch length match the OEM specification, allowing direct installation without thread chasing or dimensional adjustment.
- Genuine OEM Component — Sourced directly from Multiquip, this screw carries the same part number and material spec used in original production, giving you confidence in joint integrity and torque performance.
- Confirmed Fitment for LT6K and LT6KV — Validated for use on LT6K and LT6KV (60Hz) towable light towers, so you can order with confidence knowing this is the correct fastener for your machine.
- Structural Joint Reliability — A correctly specified fastener maintains clamping force under the vibration and transport loads that towable light towers routinely experience. An undersized or incorrect-grade screw risks joint loosening or fastener shear over time.
A hex head cap screw like the Multiquip 3437 serves as a primary mechanical fastener in structural and component-mounting joints throughout the light tower assembly. Its Grade 8 rating means it is manufactured to a defined minimum tensile and proof load, making it suitable for joints that must hold under dynamic loads, vibration, and repeated stress cycles. Using a lower-grade or incorrect-length substitute in these positions can result in joint movement, component misalignment, or fastener failure — issues that are difficult to detect until a more significant problem develops.
