Hillman Fasteners 150003 1/4-20 Hex Nut 100 Pack

Product Description

The HILLMAN FASTENERS 150003 is a 100-pack of 1/4-20 coarse thread hex nuts manufactured from zinc plated steel. These nuts are a standard fastening component used across HVAC, plumbing, electrical, and general mechanical assembly applications. The 1/4-20 thread designation indicates a 1/4-inch nominal diameter with 20 threads per inch, conforming to Unified Coarse (UNC) thread standards. The zinc plating provides a basic level of corrosion resistance suitable for indoor and sheltered installations. Each pack contains 100 individual hex nuts, making this a practical bulk quantity for service vehicles, shop stock, or job-site use.

These hex nuts are suited for residential and light commercial trade work wherever 1/4-20 fasteners are specified. Common applications include equipment mounting, panel assembly, conduit support hardware, ductwork components, and general mechanical connections. The coarse thread profile allows for faster installation and greater resistance to cross-threading compared to fine thread alternatives, which is an advantage in field conditions. Electricians, HVAC technicians, and plumbers routinely stock 1/4-20 hardware for bracket and support installations.

Key Features

• 1/4-20 coarse thread (UNC) for broad compatibility with standard 1/4-inch fastener systems
• Zinc plated steel construction provides corrosion resistance for general indoor use
• 100-piece pack quantity supports bulk stocking for service and installation work
• Hex drive geometry accepts standard 7/16-inch open-end, box, or socket wrenches
• Coarse thread profile reduces risk of cross-threading during field installation

Compatibility

Designed for use with any 1/4-20 UNC threaded bolt, stud, or rod in standard trade fastening applications.

Installation Notes

Installation of hex nuts does not require a licensed trade but is commonly performed by HVAC technicians, electricians, and plumbers during equipment and support hardware assembly. Use a properly sized wrench or socket to achieve a snug, firm fit without over-torquing, which can strip threads or crack mounting flanges. Ensure mating threaded components are clean and free of debris before assembly. Zinc plated hardware is not recommended for prolonged exposure to moisture, salt, or chemical environments without additional corrosion protection.
