When to use zinc plated shoulder pattern eye bolts
Zinc plated shoulder pattern eye bolts are the economical choice for angular and vertical lifts in dry and indoor conditions. The shoulder allows angular lifting when seated completely flush against the load, but remember the derating: rated capacity drops sharply with load angle, to about 25% of the vertical rating at 45 degrees, the maximum acceptable angle. The zinc plating adds corrosion resistance over bare steel. For outdoor or wet exposure, choose hot dipped galvanized or stainless. Always apply the manufacturer's angle derating, ensure the shoulder is flush, and inspect before each lift.
Why choose zinc plated steel shoulder pattern eye bolts
- Angular and vertical lifts: shoulder handles side loads when seated flush.
- Economical: cost-effective for indoor and general use.
- Corrosion resistant: zinc plating protects better than bare steel.
- Versatile: for rigging and machinery lifting points.
Common applications for zinc shoulder pattern eye bolts
- Indoor angular and vertical lifts
- Bridle slings and multi-point picks
- Machinery and equipment lifting points
- Dry rigging where side loads are possible

Zinc Plated Steel 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.
Are zinc shoulder eye bolts good outdoors?
The zinc plating suits indoor and dry use. For outdoor or wet exposure, choose hot dipped galvanized or stainless.
Does the shoulder need to be flush?
Yes. The shoulder must seat completely flush against the load surface to function safely under angular loads.
