Professional Applications & Engineering Value
Engineered for industrial machinery, electronic enclosures, and automotive assemblies, this 12-24 UNC rounded fillister head slotted screw addresses critical fastening challenges. The zinc-plated steel material combats rust and corrosion, essential for maintaining integrity in humid or outdoor settings. Its coarse thread and Class 2A thread fit enable rapid installation and reduce cross-threading risks, boosting assembly line efficiency. The high-profile fillister head with a slotted drive offers excellent torque transmission, preventing tool slippage and ensuring secure connections in high-vibration applications. Fully threaded from head to tip, it delivers uniform stress distribution, minimizing the risk of joint failure and supporting long-term operational reliability.
Specification Summary & Compliance
This screw adheres to Class 2A thread tolerance per UNC standards, ensuring precise fit and performance. Manufactured in compliance with ASME B18.6.3 specifications for dimensional accuracy and mechanical properties. It is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting environmental and safety regulations for global industrial use.
