S-95868A815 5/16"-18 x 1 1/4" Plastic Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance for reliable performance in harsh chemical environments without rust or degradation
• Excellent electrical insulation properties prevent current leakage and short circuits in electrical assemblies
• Wide temperature tolerance from -40° to 140°F maintains structural integrity across diverse operating conditions
• Precision Class 2A thread fit ensures smooth installation and consistent clamping force in UNC coarse thread applications
• 1/4" hex drive socket design provides secure tool engagement and prevents stripping during high-torque applications
• Partially threaded shank design offers optimal grip range and prevents over-tightening in precision assemblies
• RoHS 3 compliance meets international environmental standards for hazardous substance restrictions

Professional Applications & Engineering Value

This nylon socket head cap screw delivers critical engineering advantages where metal fasteners fail. The Nylon Plastic construction provides inherent chemical resistance against solvents, oils, and corrosive agents while offering complete electrical insulation - making it ideal for electrical enclosures, chemical processing equipment, and marine applications. The 5/16"-18 UNC coarse thread with Class 2A fit ensures rapid installation and vibration resistance in plastic, composite, and soft material assemblies. The standard socket head profile with 1/4" hex drive accommodates high torque applications without cam-out, while the partially threaded design provides precise clamping control. Operating across a -40° to 140°F temperature range, this fastener maintains dimensional stability in both industrial freezing conditions and elevated temperature environments.

Specification Summary & Compliance

Manufactured to inch system specifications with 5/16"-18 UNC coarse threads and Class 2A thread fit tolerance for consistent engagement. Features right-hand thread direction with partial threading and standard socket head profile. Complies with RoHS 3 (2015/863/EU) regulations restricting hazardous substances. The 1-1/4" length with 1/4" minimum thread length provides versatile fastening capability across various material thicknesses.
