S-99961A450 10-24 Hex Nuts

Key Features & Benefits at a Glance

• Left-hand threading provides secure fastening in applications requiring reverse rotation resistance
• Zinc-plated steel construction offers excellent corrosion protection for extended service life in harsh environments
• Grade 2 strength rating ensures reliable performance for general industrial applications
• UNC coarse threading enables faster installation and reduced cross-threading risks
• Standard hex profile with 3/8" width allows for easy installation using common wrenches
• Class 2B thread fit provides consistent engagement with mating components
• Compact 1/8" height saves space in confined assembly areas

Professional Applications & Engineering Value

These left-hand thread hex nuts are engineered specifically for applications where standard right-hand threading could loosen due to rotational forces or vibration. The zinc-plated steel construction provides a durable barrier against corrosion, making these UNC coarse thread fasteners ideal for industrial machinery, rotating equipment, and assembly lines where reverse-direction security is critical. The external hex drive design ensures straightforward installation and removal using standard tools, while the coarse threading reduces the risk of cross-threading during high-speed assembly operations. These nuts deliver reliable performance in demanding environments where conventional fasteners might fail.
