Professional Applications & Engineering Value
This Nylon Socket Head Cap Screw delivers critical engineering advantages where metal fasteners fail. The Nylon Plastic construction provides inherent corrosion resistance, eliminating galvanic corrosion in mixed-material assemblies and making it ideal for chemical processing, marine, and outdoor applications. Its excellent electrical insulation properties prevent short circuits in electrical enclosures, control panels, and automotive electronic systems. The UNC coarse threads with Class 2A fit ensure rapid installation and reliable holding power in plastic, composite, and soft material applications. The partially threaded design concentrates clamping force precisely where needed, while the 1/4" hex drive socket head provides superior torque transmission compared to slotted plastic fasteners.
Specification Summary & Compliance
This inch-system fastener features 5/16"-18 UNC coarse threads with Class 2A thread fit for standard industrial applications. The partially threaded design provides 2 1/2" overall length with minimum 1 1/16" thread engagement. Manufactured to industry standards for Socket Head Cap Screws with right-hand thread direction and standard socket head profile. Compliant with RoHS 3 (2015/863/EU) regulations for hazardous substance restriction, ensuring environmental responsibility and global market acceptance.
