S-90114A543 8-32 x 1/4" ASME B18.6.3 Brass Fillister Head Slotted Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with high-quality brass construction, ideal for humid or chemically exposed industrial environments
• Enhanced torque transmission from the deep, narrow fillister head design, reducing cam-out during installation
• Reliable coarse threading (UNC) ensures quick assembly and secure fastening in softer materials
• Consistent Class 2A thread fit provides smooth engagement and reduces cross-threading risks
• High tensile strength (50,000 psi) and Rockwell B40 hardness deliver exceptional durability under mechanical stress
• Full threading along the 1/4" length maximizes grip and load distribution across the entire fastener
• Compliance with ASME B18.6.3, RoHS 3, and REACH guarantees safety, quality, and environmental responsibility

Professional Applications & Engineering Value

Engineered for precision and longevity, these 8-32 UNC brass slotted screws address common industrial challenges like corrosion, vibration loosening, and assembly efficiency. The rounded fillister head offers a low-profile yet robust design, allowing for higher torque application without stripping the slotted drive. Made from durable brass material, they resist oxidation and galvanic corrosion, making them ideal for electrical enclosures, marine hardware, and plumbing systems. The coarse thread and Class 2A fit ensure quick, reliable fastening in wood, plastic, or soft metals, reducing installation time and maintenance costs in assembly lines and machinery.

Specification Summary & Compliance

This screw adheres to ASME B18.6.3 dimensional standards, with precise Class 2A thread fit for consistent performance. It features a right-hand UNC thread with 0.164" diameter and coarse spacing, fully threaded over a 1/4" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets environmental and safety requirements for industrial use.
