S-91970A712 1/2"-13 x 1" Plastic Hex Head Screws

Key Features & Benefits at a Glance

• Corrosion-resistant black nylon construction ensures long-lasting performance in harsh environments without rust or degradation.
• External hex drive design allows for quick and secure installation with standard tools, reducing assembly time.
• Class 2A thread fit with UNC coarse threading provides reliable engagement and vibration resistance in various materials.
• Wide operating temperature range (-40° to 185°F) maintains integrity in both freezing and elevated heat conditions.
• RoHS 3 compliance guarantees environmental safety and adherence to international regulatory standards.
• Fully threaded 1-inch length offers consistent holding power along the entire shaft for uniform load distribution.
• Lightweight plastic material reduces overall weight in assemblies while providing excellent electrical insulation.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these nylon plastic hex head screws with 1/2"-13 UNC coarse threads deliver exceptional value in applications where metal fasteners are unsuitable. The black nylon material inherently resists corrosion, chemicals, and moisture, eliminating galvanic corrosion risks in electrical enclosures, marine equipment, and food processing machinery. The external hex drive ensures high torque application without stripping, while the Class 2A thread fit prevents cross-threading in repetitive assembly lines. Ideal for plastic fabrication, automotive components, and outdoor structures, these screws provide reliable fastening without conductive or thermal expansion issues, streamlining maintenance and reducing total cost of ownership.
