Professional Applications & Engineering Value

This nylon plastic socket head cap screw delivers critical engineering advantages where metal fasteners fail. The 1/4"-20 UNC coarse thread configuration with Class 2A fit provides reliable engagement in plastic and soft material applications, resisting stripping while maintaining consistent clamping force. The hex drive socket head design enables high-torque installation in confined spaces, while the nylon material inherently resists chemicals, solvents, and moisture that typically degrade metal components. These socket head cap screws are engineered for electrical enclosures, food processing equipment, marine applications, and chemical handling systems where corrosion resistance and electrical insulation are mandatory. The fully threaded design ensures maximum thread contact throughout the engagement length, providing superior vibration resistance in dynamic applications.

Specification Summary & Compliance

Manufactured to inch system specifications with 1/4"-20 UNC coarse threads meeting Class 2A dimensional tolerances for consistent fit and performance. The socket head cap screw features standard hex drive configuration with 3/16" drive size. Compliant with RoHS 3 (2015/863/EU) regulations for environmental safety, containing no restricted hazardous substances. Suitable for temperature applications ranging from -40° to 140°F while maintaining mechanical properties and dimensional stability.
