Key Features & Benefits at a Glance
- Corrosion-resistant PVC construction ensures long-lasting performance in humid or chemical environments, eliminating rust concerns.
- External hex drive design provides secure tool engagement for quick and easy installation with standard wrenches.
- Coarse UNC threading with Class 2A fit offers faster assembly and reliable grip in plastic or soft materials.
- Partially threaded shank allows for precise clamping force control, preventing over-tightening in delicate assemblies.
- RoHS 3 compliance guarantees environmentally safe manufacturing, meeting strict international regulatory standards.
- 140°F temperature rating makes these screws suitable for moderate thermal applications without deformation.
- Gray color and inch system sizing provide easy identification and compatibility with North American industrial specifications.
Professional Applications & Engineering Value
These PVC hex head screws are engineered to address common industrial challenges where metal fasteners fail. The gray PVC material inherently resists corrosion, making them ideal for electrical enclosures, water treatment systems, and outdoor equipment where moisture exposure is constant. The 5/16"-18 UNC coarse thread design ensures rapid installation in plastic panels or composite materials, reducing assembly time while maintaining a secure Class 2A thread fit. With a partial threading configuration, they provide controlled clamping force, preventing material stress in applications like HVAC ducting or chemical processing fixtures. Their external hex drive allows for high-torque application without stripping, offering reliability in maintenance-heavy environments.
Specification Summary & Compliance
This screw features a 5/16"-18 UNC coarse thread with Class 2A thread fit for consistent dimensional accuracy. It is manufactured to inch system standards with a 1 1/2" length and partial threading up to 1". The product is fully RoHS 3 (2015/863/EU) compliant, ensuring adherence to hazardous substance restrictions. While not rated for hardness, it operates reliably up to 140°F in industrial applications.
