Multiquip EE15973 Nut 1/4-20 With Spring 1-5/8" Unistrut

The Multiquip EE15973 is a genuine OEM Nut 1/4-20 With Spring 1-5/8" Unistrut designed for DEFTANK1 and DEFTANK2 MQ Power Fuel and DEF Tank systems. As a direct OEM replacement, EE15973 ensures correct engagement with Unistrut channel framing, delivering the same clamping performance as the original hardware. This spring-loaded channel nut is built to the same specifications as the part that left the factory, making it a dependable choice when servicing or rebuilding your tank mounting structure. Confirm your model code against DEFTANK1 or DEFTANK2 before ordering to ensure an exact match.

Key Features

• Genuine OEM Hardware Grade — Spring tension and thread specification match the original 1/4-20 channel nut, ensuring correct clamping force within the Unistrut channel slot.
• Spring-Loaded Channel Engagement — The integrated spring holds the nut in position within the Unistrut channel before fastening, allowing single-handed placement and faster installation on tank mounting assemblies.
• Confirmed Fitment for DEF Tank Systems — Verified for DEFTANK1 and DEFTANK2 MQ Power Fuel and DEF Tank units, so you can order with confidence.
• Structural Mounting Integrity — A correctly torqued Unistrut channel nut keeps tank mounting frames secure under vibration and load; worn or stripped hardware can allow movement that stresses hoses, fittings, and tank walls.
• Fuel and DEF System Safety Relevance — Secure mounting hardware is essential in fuel and DEF tank installations where loose components can create leak points or regulatory compliance issues during operation and transport.

A Unistrut spring channel nut is a fastener designed to slide into the open slot of a strut channel and lock into place when rotated 90 degrees, with the spring holding it in position until the mating bolt is tightened. In tank mounting applications, these nuts anchor brackets, clamps, and support rails that hold the fuel or DEF tank securely to the frame. When the spring loses tension or the threads are damaged, the fastener can slip or fail to clamp properly, compromising the stability of the entire tank assembly and potentially leading to vibration-induced wear on connected components.
