S-92929A159 8-32 x 1/4" 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 chemical environments without rust concerns
• Secure Class 2A thread fit ensures consistent engagement and reliable fastening in repetitive assembly operations
• Wide temperature tolerance from -40°F to 185°F maintains integrity in varied thermal conditions
• Standard 100° countersink angle allows for flush mounting, reducing snagging and improving aesthetic finish
• RoHS 3 compliance guarantees environmental safety and meets international regulatory standards
• Fully threaded design provides maximum grip length and uniform stress distribution
• Lightweight nylon material reduces overall assembly weight while offering good electrical insulation properties

Professional Applications & Engineering Value

This 8-32 UNC coarse thread nylon plastic flat head screw is engineered to address common industrial challenges such as corrosion, electrical conductivity, and weight reduction. The nylon material inherently resists moisture, chemicals, and galvanic corrosion, making it perfect for electrical enclosures, marine equipment, and food processing machinery. Its 100° countersink angle and flat head design ensure a smooth, flush finish that prevents interference in moving parts. With a temperature range of -40°F to 185°F, it performs reliably in both freezing and moderately high-temperature environments, while the fully threaded right-hand UNC coarse threading ensures quick installation and strong holding power in plastic, wood, or soft metal substrates. This screw is an optimal choice for lightweight assembly, insulating applications, and RoHS-compliant production lines.

Specification Summary & Compliance

This fastener adheres to Class 2A thread fit per UNC standards, ensuring precise dimensional accuracy and interchangeability. It is manufactured in compliance with ASME B18.6.3 for consistent quality and performance. The screw is RoHS 3 (2015/863/EU) Compliant, confirming it is free from hazardous substances, and operates within a specified temperature range of -40°F to 185°F. The inch system measurements, including thread size 8-32 and length 1/4", provide compatibility with standard imperial components.
