Midwest Fasteners Grade MR Plastic Nylon Hex Nut

Midwest Fasteners Grade MR Plastic Nylon Hex Nut

The Midwest Fasteners Grade MR plastic nylon hex nut is a molded hex nut built from durable nylon material, designed for applications where a lightweight, non-metallic fastener is preferred over standard steel or stainless hardware. This family is available in #10 and #14 sizes, covering the common range needed for light-duty assembly, panel work, and general repair jobs around the shop or jobsite. Because the body is molded plastic rather than metal, it resists corrosion by nature of its construction and will not conduct electricity, which matters anywhere a steel or stainless nut would be the wrong call. Every size in this family shares the same Grade MR plastic specification and a standard hex nut profile, so it threads onto matching fasteners and seats consistently regardless of which size from the range is selected.

Key Features

• Size Range: Available in #10 and #14 to match common fastener diameters used in light-duty assembly.
• Material: Molded plastic construction delivers a lightweight, non-conductive, corrosion-resistant fastener body.
• Finish: Nylon finish adds surface durability and a smooth, consistent thread engagement every time it's installed.
• Grade: Manufactured to a Grade MR plastic specification for consistent performance and fit across both sizes.
• Hex Profile: Standard six-sided nut head accepts common hand tools, wrenches, and nut drivers at every size.
• Non-Metallic Construction: A plastic/nylon build means no rust streaking and no risk of galvanic corrosion when paired with dissimilar metal hardware.
• Shop-Ready Sizing: Manufactured to consistent hex nut dimensions for predictable fit in maintenance and repair work across the #10 to #14 range.

Technical Specifications

• Grade: MR

Typical Applications

• General maintenance and repair projects calling for a lightweight, non-metallic nut instead of plated steel.
• Applications where the corrosion resistance of a plastic/nylon build is preferred over standard plated hardware.
• Equipment assemblies where the electrical non-conductivity of a plastic fastener is a benefit, not a liability.
• Replacement hardware for panels, covers, and light-duty fixtures that use a standard hex nut.
• Shop and jobsite hardware bins stocking a plastic alternative to steel hex nuts across multiple common sizes.
