S-92929A112 2-56 x 5/16" ASME B18.6.3 Plastic Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Excellent corrosion resistance due to nylon plastic construction, ideal for humid or chemically exposed environments
• Secure and flush mounting with standard 82° countersink angle, preventing snagging and providing a smooth surface finish
• Reliable thread engagement with Class 2A thread fit and coarse UNC threading for quick assembly and vibration resistance
• Broad temperature tolerance from -40° to 185°F, maintaining performance in varied operating conditions
• Full thread coverage along the 5/16" length for maximum grip and holding power in plastic or soft materials
• Industry-standard compliance with ASME B18.6.3 and RoHS 3, ensuring quality and environmental safety
• Easy manual installation with slotted drive design, requiring only basic tools for straightforward fastening

Professional Applications & Engineering Value

Engineered for precision fastening in electrical enclosures, automotive trim, and consumer electronics, these nylon plastic flat head screws provide exceptional electrical insulation and eliminate galvanic corrosion risks when mating with dissimilar metals. The fully threaded UNC coarse spacing ensures rapid installation and superior pull-out resistance in plastic housings and soft substrates. With an operating range from -40° to 185°F, they maintain dimensional stability in both freezing and elevated temperature environments. The standard 82° countersink angle creates seamless flush mounting while the slotted drive accommodates manual assembly lines. These RoHS 3 compliant fasteners deliver non-conductive, lightweight solutions where metal screws would cause interference or weight penalties.
