Professional Applications & Engineering Value

Engineered for precision assembly, these 12-24 UNC slotted screws deliver exceptional performance in machinery, electronics, and automotive systems. The zinc-plated steel construction provides a durable barrier against oxidation, while the coarse thread design enables quick installation and high resistance to loosening under vibration. The fillister head with its high, narrow profile is ideal for applications requiring deep counterbores or limited headspace, ensuring secure fastening without protruding components. With a Rockwell B69 hardness and 60,000 psi tensile strength, these screws maintain integrity in high-stress environments, reducing maintenance cycles and enhancing operational reliability. Their fully threaded configuration ensures uniform load distribution, making them suitable for critical joints in industrial equipment and metal fabrications.

Specification Summary & Compliance

This fastener adheres to Class 2A thread fit per UNC standards, ensuring precise dimensional accuracy and interchangeability. Manufacturing complies with ASME B18.6.3 specifications for slotted head screws, guaranteeing consistent quality and performance. Environmental and safety regulations are met through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming the absence of restricted substances. The right-hand coarse thread (12-24 UNC) and 1" length provide reliable fastening in various materials, supported by full threading for optimal grip strength.
