Anchor U-bolt UN KOTWA U M12L-300MM with plate and 2 nuts, model LBKUB 12×300

UN KOTWA U-bolt anchor M12 L=300 mm with plate and two nuts is a metal fastening element designed to secure pipes, rails and various structural components to concrete and masonry. The U-shaped rod with a 12 mm diameter and 300 mm leg length provides mechanical clamping through the supplied mounting plate and two hex nuts. The design is straightforward and intended for use in construction, installation and repair tasks where a robust, reusable clamp is required.

Advantages

The U-bolt anchor offers simple mechanical fixation without the need for special adhesives or chemical anchors, allowing for quick installation and removal. Supplied as a complete set with a mounting plate and two nuts, it ensures even pressure distribution across the clamped element and improved resistance to rotation and loosening. The metal construction provides durability and suitability for indoor and some sheltered outdoor applications when appropriate corrosion protection is present.

Suitable for

• Fixing round and rectangular pipes to concrete or masonry surfaces
• Securing handrails, guardrails and small structural members
• Temporary or permanent fastening in maintenance and repair work
• Mounting cable trays, conduit runs or HVAC components

Key specifications

• Rod shape: U-bolt (U-shaped)
• Rod diameter: 12 mm
• Leg length: 300 mm
• Included accessories: mounting plate and two nuts
• Material: metal (steel)
• Connection type: threaded ends with nuts for mechanical clamping

How to use

Drill holes or position the U-bolt around the element to be fixed and align the legs with the prepared anchors or through-holes in the concrete or masonry. Slide the mounting plate onto the threaded ends, insert the legs through the holes, and tighten the two nuts until the plate secures the clamped item with consistent pressure. Ensure the U-bolt fits the pipe or profile diameter before final tightening and avoid over-torquing, which can deform the clamped component or threads.

Usage recommendations

Inspect mounting surfaces for stability and choose appropriate hole anchors or through-bolting methods for the substrate. Use corrosion-resistant coatings or stainless material where exposure to moisture or aggressive environments is expected. Follow recommended torque values for M12 threaded connections and check fastening periodically in high-vibration or load-bearing applications.
