Professional Applications & Engineering Value

These 5-40 UNC brass rounded head slotted screws are engineered to address common industrial challenges such as corrosion, electrical interference, and mechanical stress. The brass material inherently resists rust and galvanic corrosion, making these screws ideal for marine, plumbing, and electronic enclosures where moisture exposure is a concern. The coarse thread design ensures secure engagement in softer materials or applications prone to vibration, reducing the risk of loosening over time. With a fully threaded shank and high tensile strength, they provide consistent clamping force in assembly lines, electrical panels, and machinery maintenance. Their compliance with ASME B18.6.3 guarantees dimensional accuracy and interchangeability, streamlining procurement and inventory management for B2B buyers.

Specification Summary & Compliance

These screws feature precise Class 2A thread fit per UNC standards, ensuring consistent engagement and ease of assembly. Manufacturing adheres to ASME B18.6.3 specifications for dimensional integrity, including head diameter (0.236") and length (1/2"). They are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances for safe use in global markets.
