The Light Source Uni-Bolt is a specialized fastener engineered for secure attachment to low-profile Unistrut channels, also known as strut channels or metal framing systems. This bolt is designed with a unique head shape that allows it to be inserted into the channel's slot and rotated ninety degrees, locking it securely in place without the need for additional nuts inside the channel. It is finished in a durable black coating, such as zinc plating or a similar corrosion-resistant treatment, providing both protection and a low-visibility appearance. The bolt typically features a standard machine thread on its shank, allowing a nut to be tightened onto it to clamp components—such as pipe clamps, electrical boxes, or brackets—firmly against the strut channel, creating a robust and adjustable mechanical connection.

This fastener is a fundamental component for constructing modular support frameworks in electrical, mechanical, and audiovisual installations. Its low-profile design is specifically intended for use with shallow or "low profile" strut channels where the clearance between the channel's lips is minimal. The innovative head design streamlines the installation process significantly; the installer simply drops the bolt into the channel's open slot, twists it to seat the head under the channel's internal flanges, and then places the item to be mounted over the bolt before securing it with a washer and nut. This eliminates the time-consuming process of sliding a traditional spring nut along the entire length of the channel, making it ideal for retrofit applications or adding mounting points at specific locations.

The Uni-Bolt's utility is vast, serving as the critical link between the structural strut channel and the equipment it supports. It is commonly used to hang pipe for lighting trusses, mount audio speakers, secure cable trays, or install HVAC components. The black finish helps it blend into the shadowed interior of the channel and with other black hardware. By providing a quick, secure, and reusable mounting solution, the Light Source Uni-Bolt enhances the flexibility and efficiency of working with Unistrut systems, allowing for strong, reliable, and easily adjustable installations in commercial, industrial, and production environments.
