S-90275A192 8-32 x 3/8" ASME B18.6.3 Steel Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel coating, extending service life in harsh industrial environments.
• High tensile strength of 60,000 psi ensures reliable load-bearing capacity and prevents fastener failure under stress.
• Rockwell B70 hardness provides excellent wear resistance and maintains thread integrity during repeated use.
• Fully threaded design offers maximum grip and uniform holding power along the entire screw length.
• Class 2A thread fit with UNC coarse threading enables quick, easy installation and reduces cross-threading risks.
• Standard 82° countersink angle allows for flush mounting in pre-drilled holes, creating a smooth surface finish.
• Slotted drive style facilitates straightforward installation with common hand or power tools.

Professional Applications & Engineering Value

These 8-32 UNC flat head screws are engineered from zinc-plated steel to address common industrial fastening challenges, such as vibration loosening and environmental corrosion. The coarse UNC thread and full threading provide enhanced pull-out resistance in materials like metal, wood, and plastic, making them ideal for assembly lines, machinery, and electrical enclosures. The flat head design with an 82° countersink ensures a secure, flush fit that minimizes protrusion risks in tight spaces. With a 60,000 psi tensile strength and Rockwell B70 hardness, these screws deliver consistent performance in high-stress applications, reducing maintenance needs and downtime.
