Professional Applications & Engineering Value
Engineered for demanding industrial settings, this 4-40 UNC nylon plastic screw combines material resilience with precision threading to address common fastening challenges. The nylon plastic body inherently resists chemicals, moisture, and corrosion, making it superior to metal fasteners in HVAC, electronics, and outdoor equipment. Its coarse thread and Class 2A fit ensure rapid, vibration-resistant installation in thermoplastic components, reducing assembly time and thread stripping risks. The pan head with Phillips drive offers a secure, low-profile hold that withstands thermal cycling from -40° to 185°F, providing long-term durability in automotive, consumer appliances, and packaging machinery without compromising electrical insulation.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. It features a 4-40 thread size, 9/32" length, and fully threaded construction. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures it meets stringent environmental and safety regulations for industrial use.
