- Full threading along 5/16" length delivers maximum grip strength and uniform load distribution
Professional Applications & Engineering Value
Engineered for precision assemblies requiring non-conductive, corrosion-resistant fastening solutions, these nylon plastic flat head screws solve critical challenges in electrical enclosures, marine equipment, and food processing machinery. The 2-56 UNC coarse thread configuration provides excellent pull-out resistance in plastic and soft metal substrates, while the 100° countersink angle ensures seamless integration into tapered recesses. Particularly valuable in electrical insulation applications, these screws prevent galvanic corrosion between dissimilar metals and maintain integrity in environments where metal fasteners would degrade. The slotted drive style offers compatibility with standard installation tools, making them ideal for maintenance-sensitive industrial equipment.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerances ensuring precise dimensional accuracy. These screws feature UNC coarse threads (2-56 size) with right-hand orientation and full threading along the 5/16" length. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and material safety standards for global industrial applications.
