Why use 304 stainless for shoulder pattern eye bolts?
304 stainless gives strong corrosion resistance for outdoor and freshwater use, and the shoulder pattern allows both vertical and angular lifts when the shoulder is seated completely flush against the load. Remember the derating: rated capacity drops sharply with load angle, to about 25% of the vertical rating at 45 degrees, which is the maximum acceptable angle. Pair it with 304 or 18-8 stainless hardware. For coastal or saltwater exposure, step up to 316 where available. Always apply the manufacturer's angle derating, ensure the shoulder is flush, and inspect before each lift.
Why choose 304 stainless shoulder pattern eye bolts
- Angular and vertical lifts: shoulder handles side loads when seated flush.
- Corrosion resistant: 304 stainless resists rust in wet and outdoor use.
- Non-staining: will not rust-streak the mounting surface.
- Match grade: pairs with 304 and 18-8 stainless hardware.
Common applications for 304 shoulder pattern eye bolts
- Outdoor angular and vertical lifts
- Bridle slings and multi-point picks
- Marine-adjacent machinery lifting points
- Freshwater rigging with possible side loads

304 Stainless Shoulder Pattern 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 where available.
Does the shoulder need to be flush?
Yes. The shoulder must seat completely flush against the load surface to reduce bending stress and function safely under angular loads.
