Professional Applications & Engineering Value
Engineered for precision fastening in industrial settings, these 4-40 UNC brass slotted rounded head screws address critical needs for corrosion-resistant components in electrical enclosures, marine hardware, and plumbing systems. The coarse thread design ensures quick assembly and reliable holding power in softer materials, while the fully threaded configuration provides consistent clamping force across the entire length. Brass material inherently resists galvanic corrosion and maintains conductivity, making these screws ideal for electronic assemblies and outdoor applications where environmental factors degrade inferior fasteners. The combination of ASME B18.6.3 compliance and standardized dimensions guarantees interchangeability and fitment accuracy in OEM and MRO scenarios.
Specification Summary & Compliance
Manufactured to exact Class 2A thread fit tolerances per UNC standards, ensuring precise engagement with mating components. These screws conform to ASME B18.6.3 specifications for dimensional accuracy and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) adherence, confirming restriction of hazardous substances. The inch-system measurements (0.211" head diameter, 3/16" length) maintain consistency with North American industrial standards for seamless integration into existing assemblies.
