• Fully threaded design offering maximum grip length and uniform stress distribution

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 2-56 UNC thread screws with nylon patch locking technology provide reliable vibration resistance in machinery, electronic enclosures, and automotive assemblies. The black-oxide alloy steel construction combined with Rockwell C39 hardness ensures durability against wear and environmental factors. The rounded button head profile with hex drive facilitates installation in confined spaces while preventing surface damage. These fully threaded fasteners maintain clamping force under dynamic loads, making them ideal for precision equipment where coarse thread engagement and permanent locking are critical for long-term performance.
