Professional Applications & Engineering Value

These 6-32 x 3/8" flat head Phillips machine screws are engineered to address common challenges in industrial assembly, such as corrosion in humid or chemical-exposed settings. The Black-Oxide 18-8 stainless steel construction provides a durable barrier against oxidation, extending service life in machinery, electrical enclosures, and automotive components. The Phillips drive and UNC coarse threads facilitate quick installation with standard tools, reducing assembly time while the flat head design with an 82° countersink ensures a secure, flush fit that minimizes protrusion and improves aesthetic finish. Ideal for applications requiring high tensile strength and reliable performance, these screws support efficient production and maintenance workflows.

Specification Summary & Compliance

This screw features a 6-32 UNC thread size with Class 2A fit for precise dimensional accuracy, fully threaded along a 3/8" length. It meets ASME B18.6.3 specifications for manufacturing consistency and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards without hazardous substances.
