S-93140A746 6-32 x 3/8" ASME B18.6.3 Plastic Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional clarity and chemical resistance from polycarbonate material, ideal for applications requiring visual inspection or exposure to harsh environments.
• Reliable performance across a wide temperature range (-40° to 210° F), ensuring stability in both extreme cold and moderate heat conditions.
• Superior flush mounting with a standard 82° countersink angle flat head, providing a smooth, finished surface and reducing snag hazards.
• Easy installation and removal with a standard slotted drive, compatible with common hand tools for efficient assembly and maintenance.
• Secure and precise coarse threading (UNC, 6-32) with Class 2A fit, offering excellent grip and vibration resistance in various materials.
• Full threading along the 3/8" length maximizes holding power and allows for adjustable positioning in assemblies.
• Built-in corrosion resistance as a non-metallic fastener, eliminating rust and galvanic corrosion in sensitive or electrical applications.

Professional Applications & Engineering Value

This 6-32 UNC flat head slotted screw is engineered from clear polycarbonate plastic to address critical needs in industries where metal fasteners fall short. Its inherent corrosion resistance makes it perfect for chemical processing, marine, and food-grade equipment, avoiding contamination and degradation. The fully threaded design and Class 2A thread fit ensure consistent engagement and holding strength in plastic, wood, or soft metal assemblies, reducing the risk of stripping. With a temperature range from -40° to 210° F, it maintains integrity in outdoor, automotive, or electronic enclosures exposed to thermal cycling. The flat head with 82° countersink provides a sleek, low-profile finish, essential for consumer products, display units, and safety covers where protrusions are unacceptable. By specifying this screw, engineers achieve reliable, non-conductive, and visually discreet fastening solutions.
