Midwest Fasteners Hot Dip Galvanized Steel Coarse Thread Hex Nut

Midwest Fasteners Hot Dip Galvanized Steel Coarse Thread Hex Nut

The Midwest Fasteners Finished Hex Nut is a coarse thread steel hex nut finished with a hot dip galvanized coating for serious corrosion resistance on outdoor, structural and heavy-duty assembly work. This family is available in sizes from 1/4"-20 through 1/2"-13, including 1/4"-20, 5/16"-18, 3/8"-16 and 1/2"-13, so buyers can match whatever coarse thread bolt or threaded rod diameter their project calls for. Machined from steel and coated silver-gray by the hot dip galvanizing process, these finished hex nuts are built to pair with coarse thread bolts and threaded rod where exposure to moisture, weather or harsh jobsite conditions would quickly degrade a plain or lightly plated fastener. As finished hex nuts, every size in this range carries standard hex nut geometry and chamfered faces for easy driving with a wrench or socket, and each threads on smoothly thanks to the coarse thread pitch common to general construction and fabrication hardware.

Hot dip galvanizing produces a thicker, more durable zinc coating than electro-zinc plating, making these nuts a better fit for fence posts, guardrail, outdoor structures, agricultural equipment and any application left exposed to the elements. Steel construction gives every size in the range the strength needed for structural and load-bearing connections, while the coarse thread class keeps assembly forgiving on dirty, rusty or slightly damaged mating bolts compared to a fine thread nut. This is a basic, no-frills hardware line meant for buyers who already know their bolt size and thread pitch and need a matching galvanized hex nut to complete the connection, whether that is a single replacement nut or a batch for a larger fencing, decking or outdoor construction project.

Key Features

• Nut Size Range: Available from 1/4"-20 through 1/2"-13 (1/4"-20, 5/16"-18, 3/8"-16, 1/2"-13) to match coarse thread bolts and threaded rod of the same diameter.
• Type: Finished Hex Nut with standard hex wrenching flats for use with a wrench or socket.
• Material: Steel body for structural strength in general construction and fabrication applications.
• Finish: Hot Dip Galvanized coating delivers heavy-duty corrosion resistance for outdoor and exposed-weather use, far more durable than standard zinc plating.
• Thread: Coarse thread pitch across every size for easy, forgiving assembly with matching coarse thread bolts and threaded rod.
• Color: Silver-gray galvanized appearance, consistent nut to nut and size to size.

Technical Specifications

• Product Size: 1/4"-20 - 1/2"-13

Typical Applications

• Outdoor fencing, gate hardware and guardrail assembly where moisture exposure demands galvanized corrosion resistance.
• Agricultural equipment and outdoor structure construction using coarse thread bolts or threaded rod.
• Deck, dock and other exterior framing connections exposed to weather.
• General maintenance and repair work requiring a durable, weather-resistant hex nut in any size from 1/4"-20 to 1/2"-13.
• Fabrication and assembly projects pairing with galvanized or plain steel coarse thread bolts.

Why Midwest Fasteners?

Midwest Fasteners builds this hex nut line from steel and finishes every size with a true hot dip galvanized coating, giving contractors and maintenance crews a consistent, corrosion-resistant fastener for demanding outdoor work across the full 1/4"-20 to 1/2"-13 range. Coarse thread sizing keeps assembly straightforward in the field, and the finished hex nut's standard geometry means it drops into any standard wrench or socket workflow without surprises. For professionals who need dependable, weather-ready hardware on every job, this galvanized steel hex nut delivers consistent material, finish and thread quality batch after batch, size after size.
