Hex nut for 1/2"-13 threads

This DOTTIE HNT12 hex nut fits a 1/2"-13 bolt and is made from carbon steel with a Grade 2 rating. The zinc plating adds corrosion resistance for general-purpose fastening. It suits maintenance, repair and assembly tasks where a standard-height nut is required.

Simple hand or wrench installation

The nut threads onto a matching 1/2"-13 bolt by hand and is tightened with a standard wrench or socket. Cross-threading is the most common issue, so start the nut squarely and turn smoothly. Overtightening can strip the coarse threads, especially in softer mating materials.

0.427 in overall height

The nut measures .427 in tall, which determines how much bolt protrusion remains after tightening. Verify this height clears adjacent components and meets the joint's grip-length requirement. Buyers needing a thinner jam nut or a taller heavy-pattern nut should select a different style.

Questions about this item

How can I confirm the 1/2"-13 hex nut is properly seated after installation?

The nut should thread fully onto a matching 1/2"-13 bolt until the faces meet flush, with the 0.427 in height visible above the joint.

What comes in the box and what must I source separately?

The package contains the Grade 2 zinc-plated carbon steel hex nuts; you will need matching 1/2"-13 bolts or threaded rod and appropriate washers.

Which version should I choose for a standard 1/2"-13 fastening job?

The HNT12 is a single specification — 1/2"-13 thread, Grade 2 strength, zinc finish, 0.427 in height — so no alternative version exists for this thread size.
