Value Collection 06FNH 6-40 Machine Screw Hex Nut Zinc

Product Description

The VALUE COLLECTION 06FNH is a 6-40 machine screw hex nut manufactured from steel with a zinc-plated finish. It features a right-hand thread and meets the ANSI ASME B18.6.3 fastener standard for machine screw hex nuts. The 5/16-inch across-flats dimension allows for standard hex wrench or socket engagement. This nut is used in light-duty mechanical assemblies, electrical enclosures, panel fabrication, and equipment manufacturing where a compact, corrosion-resistant fastener is required. Installation is performed by hand and tool by maintenance technicians, electricians, and assembly workers across commercial and industrial applications.

The 06FNH suits applications where a fine-thread 6-40 fastener is specified, offering tighter thread engagement than coarse-thread equivalents. The zinc plating provides moderate corrosion resistance suitable for indoor and light-exposure environments. This nut is commonly used in electronic chassis assembly, sheet metal work, and small-equipment fabrication where the 6-40 thread size is called out by design specification.

Key Features

• 6-40 thread size with right-hand thread direction for standard fastening applications
• Zinc-plated steel construction for moderate corrosion resistance
• 5/16 inches across flats for standard hex tool engagement
• Meets ANSI ASME B18.6.3 fastener standard
• Thread fit class 2B for general-purpose mechanical assembly
• Compact profile at 0.114 inches height for space-constrained installations

Compatibility

Designed as a standard machine screw hex nut for use with 6-40 threaded fasteners per the ANSI ASME B18.6.3 specification in general mechanical and electrical assembly applications.

Installation Notes

Installation requires a 5/16-inch hex wrench or appropriately sized socket. Ensure mating screw threads are clean and free of debris before engagement to avoid cross-threading. Do not overtighten, as the small thread size is susceptible to stripping under excessive torque. This fastener is intended for use by qualified assembly technicians and tradespeople familiar with fine-thread fastener practices.
