DOTTIE HN34 Hex Nut 3/4"-10 Grade 2

The DOTTIE HN34 is a carbon steel hex nut with a 3/4"-10 thread pitch and a height of .617 in. It features a zinc plated finish for corrosion resistance and meets Grade 2 strength specifications. This fastener suits general purpose assembly and maintenance tasks.

Suits mechanics and DIYers needing Grade 2 strength

This nut fits applications requiring standard Grade 2 holding power and a 3/4"-10 thread. It is not for buyers who need higher tensile strength grades or different thread pitches. Users requiring stainless steel or alternative plating should look at other options.

Fits 3/4"-10 bolts and threaded rod

The component pairs with matching 3/4"-10 bolts or studs in structural or automotive builds. The zinc coating frees the joint from immediate rust concerns in dry environments. No specialised tools beyond a standard wrench are required for installation.

Questions about this item

What bolt size and thread pitch must I already have to use this 3/4"-10 hex nut?

You need a bolt with a 3/4" diameter and 10 threads per inch so the nut engages correctly.

Will this Grade 2 zinc-plated nut gall or seize when paired with an older Grade 5 or Grade 8 bolt?

The softer Grade 2 nut will deform before the higher-grade bolt, reducing galling risk; zinc plating adds lubricity during initial tightening.

How can I confirm the nut is seated properly after installation?

Measure the installed height — it should be approximately 0.617 in — and verify the bolt threads protrude slightly past the nut face.
