Value Collection 3394 Hex Nut 1/2-13 316 Stainless Unc

Product Description

The VALUE COLLECTION 3394 is a 1/2-13 hex nut machined from Grade 316 stainless steel with a bright, uncoated finish. It features a right-hand UNC thread and is used to fasten threaded fastener assemblies in applications where corrosion resistance is a priority. The 3/4-inch width across flats accepts a standard 3/4-inch wrench. At 0.05 pounds each, these nuts are suited for light mechanical assemblies, fluid system hardware, and structural connections exposed to moisture, chemicals, or salt environments. Licensed tradespeople and maintenance technicians working in marine, chemical processing, food service, and industrial plant settings commonly specify Grade 316 hardware for its superior resistance to chloride pitting compared to Grade 304.

These hex nuts are appropriate for use in HVAC equipment mounting, plumbing pipe flange connections, pool and spa equipment assemblies, and general electrical enclosure hardware where stainless fasteners are required by specification or environment. The 1/2-13 UNC thread is one of the most common coarse-thread fastener sizes in North American trade work, making this nut a standard replacement or supplemental stock item for service vans and shop bins. Sold individually with a minimum order quantity of 25 pieces.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in chloride and chemical environments
• 1/2-13 UNC right-hand thread for compatibility with standard coarse-thread fastener assemblies
• Bright, uncoated finish — no coating to flake, chip, or contribute contamination in sensitive assemblies
• 3/4-inch width across flats fits standard 3/4-inch open-end, box, or socket wrenches
• 5/16-inch height — standard hex nut profile for 1/2-inch fastener class

Compatibility

Designed for use with any 1/2-13 UNC threaded bolt, stud, or rod where a Grade 316 stainless steel hex nut is required.

Installation Notes

Installation is performed by any licensed trade professional working with fastener assemblies. Ensure mating threads are clean, free of debris, and compatible with 1/2-13 UNC specification before installation. When pairing stainless steel nuts with stainless bolts, apply an anti-seize compound to prevent galling during tightening. Follow applicable mechanical or structural codes for proper torque requirements based on joint design and load conditions.
