Professional Applications & Engineering Value
These 5-40 UNC brass screws are engineered to address common industrial challenges such as corrosion, vibration loosening, and assembly efficiency. The brass material provides inherent resistance to rust and oxidation, making them perfect for electrical enclosures, marine equipment, and plumbing systems where moisture exposure is frequent. The pan head with Phillips drive allows for quick, secure fastening without specialized tools, reducing labor costs and improving production throughput. With coarse threading and a Class 2A thread fit, these screws offer reliable engagement in soft metals and plastics, preventing strip-out and ensuring stable connections in dynamic environments. Their fully threaded design distributes load evenly, enhancing durability in industrial applications that demand consistent performance under stress.
Specification Summary & Compliance
These screws feature precise Class 2A thread fit per UNC standards, ensuring accurate engagement and ease of assembly. Manufacturing adheres to ASME B18.6.3 specifications for dimensional consistency, including a head diameter of 0.245" and length of 3/4". Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms they are free from hazardous substances, supporting safe use in regulated industries.
