S-95868A751 1/4"-20 x 2 1/4" Plastic Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance ensures long-term reliability in humid or chemically aggressive environments without rust or degradation.
• Excellent electrical insulation properties prevent short circuits and electrical interference in sensitive electronic assemblies.
• Wide operating temperature range from -40° to 140°F maintains structural integrity and performance in both freezing and moderate heat conditions.
• Precise Class 2A thread fit guarantees consistent engagement and secure fastening, reducing the risk of cross-threading or loosening.
• Partially threaded design allows for controlled clamping force and easier alignment in assemblies where full threading isn't required.
• 3/16" hex drive socket head enables high-torque installation with standard tools, speeding up assembly and disassembly processes.
• RoHS 3 compliance ensures environmental safety and meets stringent international regulations for hazardous substance restrictions.

Professional Applications & Engineering Value

This 1/4"-20 UNC nylon socket head cap screw is engineered to address critical challenges in industrial and electronic applications where metal fasteners fall short. The nylon plastic material provides inherent corrosion resistance, eliminating galvanic corrosion risks when mating with dissimilar metals and making it ideal for marine, chemical processing, and outdoor equipment. Its electrical insulation properties prevent current leakage in electrical enclosures, control panels, and PCB mounting, while the coarse UNC thread ensures rapid installation and vibration resistance in automated assembly lines. The partially threaded configuration offers precise clamping control in positioning applications, and the standard socket head profile with 3/16" hex drive accommodates high-torque installation without stripping, reducing maintenance downtime and improving overall assembly reliability.

Specification Summary & Compliance

This fastener features a 1/4"-20 UNC coarse thread with Class 2A thread fit for consistent dimensional accuracy and reliable engagement. The partially threaded rod provides a minimum thread length of 1" on a total 2 1/4" length, with a 3/8" head diameter and 1/4" head height designed for standard socket wrench compatibility. Manufactured in accordance with inch system standards, it is fully RoHS 3 (2015/863/EU) compliant, ensuring adherence to hazardous substance restrictions for global market acceptance.
