S-99091A204 8-32 x 1 1/4" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Corrosion-resistant nylon construction eliminates rust and galvanic corrosion, ideal for electrical and marine environments
• Wide temperature tolerance (-40° to 185°F) ensures reliable performance in both extreme cold and moderate heat applications
• External hex head design provides secure tool engagement for efficient installation with standard wrenches
• Class 2A thread fit with UNC coarse threading delivers consistent, reliable fastening with reduced cross-threading risk
• Full threading along the 1-1/4" length offers maximum grip and adjustment flexibility in various material thicknesses
• RoHS 3 compliance guarantees environmental safety and meets international regulatory standards
• Non-conductive and lightweight plastic material prevents electrical conductivity and reduces overall assembly weight

Professional Applications & Engineering Value

These nylon hex head screws solve critical challenges in electrical enclosures, automotive components, and food processing equipment where metal fasteners would cause short circuits or contamination. The black nylon plastic provides excellent chemical resistance against oils and solvents while maintaining dimensional stability. With 8-32 UNC coarse threads and Class 2A fit, they ensure quick assembly in plastic and soft materials without stripping threads. The external hex drive allows for high-torque installation while the temperature resistance makes them suitable for outdoor equipment and thermal cycling environments.

Specification Summary & Compliance
