Professional Applications & Engineering Value

These 6-32 UNC flat head screws are engineered from 2024 aluminum to address critical needs in lightweight yet high-stress applications. The fully threaded design and coarse thread spacing ensure rapid, secure fastening in materials where fine threads may strip or fail. The undercut flat head with an 82° countersink angle allows for a flush fit, eliminating snagging points in assemblies such as aerospace components, electronic enclosures, and precision instruments. With a tensile strength of 50,000 psi and Rockwell B55 hardness, these screws resist deformation under load, making them ideal for industrial fasteners requiring repeatable disassembly without wear. The Phillips No. 2 drive simplifies maintenance, while compliance with ASME B18.6.3 ensures dimensional consistency across batches, reducing installation errors and improving project timelines.

Specification Summary & Compliance
