Professional Applications & Engineering Value
This 5-40 UNC brass rounded head slotted screw delivers critical engineering advantages where corrosion resistance and electrical conductivity are paramount. The brass material inherently resists galvanic corrosion and weathering, making it ideal for marine, plumbing, and outdoor electrical enclosures. Its coarse thread design provides superior pull-out resistance in softer materials like plastics and wood, while the Class 2A thread fit ensures consistent engagement without binding. The slotted drive offers compatibility with standard tools for field service and maintenance operations. With fully threaded construction along its 3/4" length, it maintains maximum thread contact for vibration-resistant connections in assembly applications requiring reliable fastening performance.
Specification Summary & Compliance
This screw maintains Class 2A thread fit tolerances per UNC standards with 5-40 thread size and coarse thread spacing. Manufacturing conforms to ASME B18.6.3 specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries.
