S-94828A410 1/4"-20 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance with the unique flex-top locking design that maintains clamp load under dynamic conditions.
• Enhanced corrosion protection from cadmium-plated steel construction, ideal for harsh industrial environments.
• Efficient installation and removal using the extra-wide thin hex profile, providing better tool engagement and reduced assembly time.
• Reliable thread compatibility with Class 2B fit and 1/4"-20 UNC coarse threads, ensuring secure fastening in various assemblies.
• Space-saving low profile at only 7/32" height, allowing use in confined spaces without compromising strength.
• Durable external hex drive for high-torque applications, minimizing wear and stripping during repeated use.

Professional Applications & Engineering Value

This 1/4"-20 UNC flex-top locknut is engineered to address common challenges in machinery, automotive, and structural applications where vibration-induced loosening can lead to equipment failure. The cadmium-plated steel material offers excellent resistance to corrosion and wear, extending service life in demanding conditions. Its extra-wide thin hex profile allows for easier wrench access and improved torque application, reducing installation errors. The flex-top locking mechanism provides consistent clamping force, making it ideal for vibration-resistant assemblies such as engine components, conveyor systems, and heavy-duty fixtures. By combining precise Class 2B thread fit with a coarse thread design, it ensures quick engagement and reliable performance in high-stress environments, minimizing maintenance downtime.

Specification Summary & Compliance

This locknut features a 1/4"-20 UNC coarse thread with Class 2B thread fit for dimensional accuracy, and complies with industry standards for external hex drive and locking nuts. It meets general specifications for material and plating, with cadmium-plated steel providing corrosion resistance. The product adheres to common industrial requirements, though specific compliance such as RoHS or REACH should be verified per application needs.
