S-90276A148 6-32 x 1/2" ASME B18.6.3 Steel Round Head Slotted Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• High-reliability fastening from a 60,000 psi tensile strength and Rockwell B69 hardness, preventing failure under stress.
• Efficient installation and removal with the standard slotted drive, compatible with common hand tools.
• Optimized thread engagement through the UNC coarse thread and Class 2A fit, reducing cross-threading risks.
• Full-length threading ensures maximum grip and holding power along the entire 1/2" shank.
• Rounded head design provides a finished appearance and reduces snagging on components or wiring.
• Regulatory peace of mind with compliance to ASME B18.6.3, RoHS 3, and REACH for global supply chain suitability.

Professional Applications & Engineering Value

This zinc-plated steel rounded head screw is engineered to address common industrial challenges such as vibration loosening and environmental corrosion. The fully threaded UNC coarse thread design ensures rapid assembly and superior clamp load distribution, making it ideal for electrical enclosures, machinery panels, and automated assembly lines. The combination of 60,000 psi tensile strength and a Rockwell B69 hardness provides a durable fastening solution that maintains integrity under dynamic loads. The slotted drive offers broad tool compatibility, while the rounded head profile minimizes protrusion in space-constrained applications, enhancing both safety and aesthetics.
