S-92929A117 2-56 x 7/16" ASME B18.6.3 Plastic Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Corrosion-resistant nylon plastic construction ensures reliable performance in humid or chemically aggressive environments without rust or galvanic corrosion.
• Wide operating temperature range (-40° to 185°F) maintains structural integrity and dimensional stability in both freezing cold and elevated heat conditions.
• Class 2A thread fit with UNC coarse threading provides faster assembly, reduced cross-threading risk, and secure fastening in plastic or soft materials.
• 100° countersink angle and flat head design enables flush mounting for sleek finishes and prevents snagging in assembled products.
• Full threading along the 7/16" length offers maximum grip and adjustment flexibility across the entire fastener engagement area.
• RoHS 3 compliance and ASME B18.6.3 conformance guarantees environmental safety and mechanical reliability for regulated industries.
• Slotted drive style allows easy installation with standard screwdrivers, simplifying maintenance and field repairs.

Professional Applications & Engineering Value

Engineered for electrical enclosures, automotive trim, and consumer electronics, these nylon plastic flat head screws solve critical challenges like electrical insulation, weight reduction, and corrosion avoidance. The right-hand UNC coarse thread ensures rapid installation in thermoplastic assemblies, while the 100° countersink delivers a seamless finish that meets aesthetic requirements. With a temperature range of -40° to 185°F, they perform reliably in outdoor equipment and thermally dynamic environments where metal fasteners would fail. The fully threaded design maximizes pull-out resistance, making them ideal for vibration-prone applications where plastic fasteners must maintain clamp load without loosening.

Specification Summary & Compliance

This 2-56 UNC flat head screw features Class 2A thread fit per unified inch standards, ensuring precise tolerance for consistent engagement. Manufacturing adheres to ASME B18.6.3 specifications for dimensional accuracy and mechanical performance. The product is fully RoHS 3 (2015/863/EU) compliant, containing no restricted hazardous substances, and is designed for use in inch-system assemblies requiring corrosion-resistant fastening solutions.
