Shoulder Pattern with Nut Eye Bolts

When to use a shoulder nut eye bolt

A shoulder nut eye bolt combines two features: the shoulder that allows angular lifting when seated flush, and the extended shank that mounts through a hole and secures with a nut on the far side. That suits angular lifts through a plate, beam, or panel where you have access to both sides, rather than threading into a tapped hole. The angular rules still apply: seat the shoulder completely flush and derate for load angle, with capacity dropping to about 25% of the vertical rating at 45 degrees, the maximum acceptable angle. Choose the material for the environment, with 304 and 316 stainless for corrosion resistance and hot dipped galvanized for outdoor use. Always confirm the rated capacity and inspect before each lift.

Shoulder Pattern with Nut Eye Bolts FAQ

Why choose a shoulder nut eye bolt?

It combines angular lifting capability with through-hole mounting, securing with a nut on the far side where you have access to both sides.

Can I use these for angular lifts?

Yes, if the shoulder is seated completely flush and the capacity is derated for the load angle. At 45 degrees, capacity drops to about 25% of the vertical rating.

Does the shoulder need to be flush?

Yes. The shoulder must seat completely flush against the load surface to function safely under angular loads.
