S-96282A101 1/4"-20 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through precision serrations that bite into surfaces, preventing loosening under dynamic loads.
• Enhanced load distribution with a 19/32" flange diameter, reducing surface pressure and minimizing material stress.
• Exceptional strength and durability from Grade 8 steel construction, suitable for high-stress industrial applications.
• Reliable corrosion protection with zinc plating, extending service life in harsh environments.
• Easy installation and removal using standard external hex drive tools, improving assembly efficiency.
• Secure coarse thread engagement with UNC 1/4"-20 threading and Class 2B fit, ensuring consistent fastening performance.
• Compliance with environmental standards including REACH and RoHS 3, meeting global regulatory requirements.

Professional Applications & Engineering Value

This Grade 8 zinc-plated steel flange lock nut is engineered to address critical challenges in industrial assembly, such as vibration-induced loosening and uneven load distribution. The serrated locking design provides permanent resistance against rotational forces in machinery, automotive, and construction applications, eliminating the need for additional lock washers. Its UNC coarse thread ensures quick, reliable engagement even in debris-prone environments, while the external hex drive allows for high-torque installation with common tools. The 19/32" flange diameter acts as an integrated washer, spreading clamp load over a wider area to prevent joint fatigue and surface damage. Ideal for heavy-duty equipment and structural frameworks, this nut delivers long-term reliability under extreme operational stresses.

Specification Summary & Compliance

This flange lock nut features a 1/4"-20 UNC coarse thread with Class 2B thread fit for consistent engagement and dimensional accuracy. Manufactured from high-strength Grade 8 steel with zinc plating for corrosion resistance, it includes a standard hex profile (7/16" width) and 15/64" height. The product complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring safe use in regulated industries.
