S-90273A241 10-24 x 7/16" ASME B18.6.3 Steel Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• High tensile strength of 60,000 psi ensures reliable fastening under significant mechanical stress
• Class 2A thread fit provides smooth assembly and consistent engagement with standard UNC nuts and tapped holes
• 82° countersink angle allows for flush mounting in standard countersunk applications
• Fully threaded design maximizes grip length and load distribution across the entire fastener
• Phillips No. 2 drive enables efficient installation with common industrial tools
• Rockwell B70 hardness maintains thread integrity and prevents stripping during repeated use

Professional Applications & Engineering Value

These 10-24 UNC flat head screws deliver exceptional performance in industrial assembly where flush surface mounting is critical. The zinc-plated steel construction provides essential corrosion protection for machinery, electrical enclosures, and automotive components exposed to harsh conditions. The coarse thread design ensures rapid installation and superior resistance to vibration loosening, while the 60,000 psi tensile strength guarantees joint integrity under dynamic loads. Engineers specify these Phillips drive screws for applications requiring reliable fastening with standard tooling, from production lines to maintenance operations where Class 2A thread fit ensures compatibility with existing components.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerances for consistent performance. These fully threaded screws feature UNC coarse threads with right-hand direction and standard 82° countersink profile. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
