Professional Applications & Engineering Value
These 2-56 UNC brass flat head slotted screws are engineered to address critical fastening challenges in precision industries. The brass material provides inherent corrosion resistance, making them ideal for electrical components, marine equipment, and plumbing systems where moisture exposure is common. The UNC coarse thread design ensures rapid installation in soft materials while maintaining holding power, while the slotted drive style offers compatibility with standard tools for maintenance flexibility. With 50,000 psi tensile strength and Rockwell B50 hardness, these screws withstand vibration and mechanical stress in automotive assemblies, instrumentation, and electronic enclosures. The 82° countersink angle creates seamless flush mounting in precision machined components, eliminating protrusions that could interfere with moving parts or aesthetic requirements.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerances for consistent performance. These fully threaded 1/4" screws feature UNC coarse threads (2-56) in right-hand direction with standard flat head profile. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets.
