Professional Applications & Engineering Value

Engineered for precision-driven industries, these 2024 Aluminum flat head screws deliver critical advantages in weight-sensitive applications like aerospace components, electronic enclosures, and transportation equipment. The 5/16"-18 UNC coarse thread configuration enables rapid assembly cycles while maintaining vibration resistance, significantly reducing production downtime. With fully threaded design and 82° countersink angle, these fasteners provide maximum surface contact for stress distribution, preventing material deformation in thin-section assemblies. The Phillips No. 4 drive system ensures compatibility with standard industrial tools, while the 50,000 psi tensile strength maintains structural integrity under dynamic loads. Ideal for applications requiring RoHS 3 and REACH compliance, these screws meet stringent environmental regulations without compromising mechanical performance.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerances ensuring dimensional accuracy. The UNC coarse thread (5/16"-18) provides optimal engagement in various materials. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety. Standard right-hand thread direction with 0.313" thread diameter and 1" length maintains interchangeability with industry-standard components.
