Professional Applications & Engineering Value

This 10-32 UNF brass flat head slotted screw is engineered to address critical challenges in precision assemblies, such as corrosion resistance in marine or electrical enclosures where moisture exposure is common. The fine thread and Class 2A fit ensure tight, reliable connections in vibrating machinery, reducing maintenance needs. With a 4" length and partial threading, it provides optimal grip in layered materials without over-penetration, while the 82° countersink allows for seamless integration in aerospace or automotive panels. Made from brass, it combines non-magnetic properties with high tensile strength, making it ideal for sensitive electronic or plumbing systems where durability and compliance with ASME B18.6.3 are paramount.

Specification Summary & Compliance

This screw maintains precise Class 2A thread fit per UNF standards with a fine thread spacing for accurate engagement. Dimensions include a head diameter of 0.362", length of 4", and minimum thread length of 1-1/2", manufactured to ASME B18.6.3 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability for industrial use.
