Palnut® and Tinnerman® nut retainers and bolt retainers combine the best advantages of spring steel fasteners with the unparalleled fastening strength of a multi-threaded nut. Nut and bolt retainers are self-retaining and cannot turn as the bolt is tightened, resulting in positive, high-torque attachment. Each nut retainer snaps readily into bolt-receiving position at panel edges or center-panel locations and allows the nut to float within the spring steel cage, offsetting any possible hole misalignment.

Both nut retainers and bolt retainers are available in a variety of sizes and designs from Bolt Products to fit a wide range of mounting holes and screw sizes. Select the type of retainer your project requires below.


Advantages of Retaining Nut

Enhanced Fastening Strength: Retaining nuts offer unparalleled fastening strength, owing to their multi-threaded design and robust construction. By effectively distributing the applied torque along multiple threads, these nuts facilitate a secure and stable connection, minimizing the risk of loosening or failure even under challenging operating conditions.

Self-Retention Mechanism: The inherent self-retention mechanism of retaining nuts prevents rotation during bolt tightening, ensuring precise and reliable fastening. This feature eliminates the need for manual intervention or additional tools, simplifying assembly procedures and reducing labor costs.

Flexibility and Adaptability: Retaining nuts are available in a variety of sizes, designs, and materials to accommodate diverse application requirements. Whether it's panel mounting, center-panel installations, or offsetting hole misalignment, these nuts offer flexibility and adaptability, making them suitable for a wide range of industrial and commercial applications.
