Thread: Eye Bolts or Eye Nuts which is better?

In practical terms I doubt there is any difference, since your safety factor should be so large that any differences are irrelevant.

But the eye bolt would be a bit stronger, I would think, in that any side load is resisted by the shank directly rather than having to be relayed through the thread. But a straight pull would be the same except I'm not sure you can get 'high tensile' eye bolts.

The most important difference, more important than nut/bolt is to have the largest pad behind the eye, again, to resist side loads.

What I did last time was use Eye Bolts, I positioned them in the bar in line with the chassis rails. Inside the ARB bar the way it's weld up there is a box section that bolts to the chassis. I put a plate as large as it will fit in there 8mm thick.

Rob - you've raised a good point - what the eye bolt is attached to is probably more important than whether it is a bolt or nut!

From Google:
Shoulder Eye Bolts Stainless Steel

Shoulder eye bolts allow you to lift or place the load at an angle. Stainless steel heavy duty construction. The shoulder supports line load at angles.

The lifting eye nut is perfect for applications where you have to bolt through a thick deck. Use a stainless steel bolt from below with the lifting eye nut on top. For extra strength use a forged lifting eye nut.

For 3600kg at a 45 degree pull angle, you need a 30mm base on the eye nut.

Ok whilst talking to a friend who moves machines every day for a living, he suggested I look at these load rings as they have a rated working lift load and design factor of 4:1 in any direction. They also swivel 360° in any direction.

Load ring VLBG 4t M24 with bolt


Ref.-No.: 8500827
Nominal WLL: 4000 kg
Weight: 1,50 kg


T: 125 mm
A: 50 mm
B: 82 mm
C: 54 mm
D: 58 mm
E: 67 mm
F: 18 mm
G: 43 mm
H: 37 mm
J: 130 mm
K: 78 mm
L: 80 mm
M: 24 mm
N: 48 mm

I would use the load rings over eye bolts any day. The reason is that eye bolts are designed to take load only when it is vertical to the bolt, and not any other way
