- RoHS 3 compliance guaranteeing environmentally safe materials free from hazardous substances
- Partially threaded shank design providing unthreaded grip length for enhanced clamping force in assembled joints
Professional Applications & Engineering Value
These Gray PVC Hex Head Screws deliver exceptional value in applications where metal fasteners would corrode or contaminate processes. The PVC plastic material offers inherent resistance to chemicals, moisture, and electrical non-conductivity, making them perfect for water treatment facilities, chemical processing equipment, and food handling machinery. The 1/2"-13 UNC coarse threads ensure quick installation in plastic frames, composite panels, and wooden structures, while the external hex drive permits high torque application without stripping. With a 3" length and partial threading, they provide optimal unthreaded shank sections for improved shear strength, solving common issues of thread fatigue in dynamic load environments.
Specification Summary & Compliance
This screw features a 1/2"-13 UNC thread with Class 2A thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and interchangeability. Key dimensions include 0.5" thread diameter, 1 1/2" minimum thread length, 13/32" head height, and 3/4" head width. Manufactured from PVC plastic in gray color with inch system measurements, it is fully RoHS 3 (2015/863/EU) compliant for environmental safety in industrial applications.
