Why use 304 stainless for shoulder nut eye bolts?
304 stainless gives strong corrosion resistance for outdoor and freshwater use, combined with the shoulder that allows angular lifting and the extended shank that mounts through a hole and secures with a nut on the far side. The angular rules apply: seat the shoulder completely flush and derate for load angle, with capacity dropping to about 25% of the vertical rating at 45 degrees. Pair it with 304 or 18-8 stainless nuts and washers. For coastal or saltwater exposure, step up to 316. Always confirm the rated capacity, ensure the shoulder is flush, and inspect before each lift.
Why choose 304 stainless shoulder pattern with nut eye bolts
- Angular and vertical lifts: shoulder handles side loads when seated flush.
- Through-hole mount: secures with a nut on the far side.
- Corrosion resistant: 304 stainless resists rust in wet and outdoor use.
- Match grade: pairs with 304 and 18-8 stainless hardware.
Common applications for 304 shoulder nut eye bolts
- Outdoor angular and vertical through-hole lifts
- Bridle slings and multi-point picks
- Mounting through plates, beams, and panels
- Marine-adjacent rigging with side loads

304 Stainless Shoulder Pattern with Nut Eye Bolts FAQ
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.
Is 304 good for coastal use?
304 handles most outdoor and freshwater exposure but can pit in salt. For coastal or saltwater use, choose 316.
Does the shoulder need to be flush?
Yes. The shoulder must seat completely flush against the load surface to function safely under angular loads.
