MF Locknuts

Tengco Is Your Leading MF Locknut Manufacturer

An MF locknut, also known as a jam nut or securing nut, is used to secure another nut or bolt in place. Tengco offers standard locknuts in various sizes and thread types to fit multiple applications. They work by creating friction between the locknut's threads and the threads of the primary nut or bolt. This friction helps to prevent the primary nut or bolt from loosening due to vibration or movement.

In addition to standard sizes, we also offer custom locknuts that can be manufactured to meet your specific needs. This is especially valuable for applications where standard nuts may not be suitable due to unique size requirements, material needs, or environmental conditions. Let us know your specific requirements, and our team of experts will work with you to design and manufacture the perfect custom locknut for your project.

Understanding MF Locknuts: Key Features for Secure Connections

Learn more about how a locknut makes a secure connection:

• Locking Mechanism: MF locknuts are a secondary fastening mechanism commonly used for utility pole connections. They are typically installed as a fastener on the back of a square or hex nut, ensuring that the primary nut doesn’t loosen due to vibration or other movement.

• Fast and Easy Installation: One significant advantage of MF locknuts is their ease of installation. This type of nut is designed to spin freely by hand, saving time and energy for your assembly projects. Because they’re user-friendly, locknuts are reliable fasteners for installations where efficiency is essential.

• Built to Stay Tight: MF locknuts feature a unique design that flattens permanently when tightened down. Think of it like a built-in grip that gets even stronger over time. This permanent set ensures your connection stays secure, regardless of vibrations, temperature changes, or other challenges. Tengco offers a locknut solution that assures your connection remains strong and secure.

Custom Locknut Solutions for You

At Tengco, we know that different applications have nonstandard requirements and specifications. In addition to standard MF locknuts, we also offer custom fasteners with precise fitment for your unique projects.

• The Right Fit: An oversized locknut won't create the friction needed for a secure hold. Undersized ones won't engage the threads properly, leaving your connection vulnerable to loosening and potential failure. It's like using the wrong size wrench – a loose fit means the job won't be done right.

• Coated To Last: Locknut coatings are vital armor. Over time, uncoated fasteners can rust, seize, or weaken in harsh environments, compromising their grip and risking connection failure. The right coating shields your locknuts, ensuring they stay strong and reliable even when facing rain, wind, snow, and other outdoor elements.

• Parts When You Need Them: Our "stock and release" program keeps you running smoothly. Instead of managing a full inventory of custom parts, tell us what you need, and we'll pre-build your order. This frees up your storage space and ensures you have the right custom locknuts exactly when needed, keeping your projects on track.
