Why use 8620 alloy steel for shoulder eye bolts?
8620 is a case-hardening alloy steel with a strong, tough core, which suits forged lifting eye bolts that carry heavy loads without deforming. The shoulder pattern allows both vertical and angular lifts when the shoulder is seated completely flush against the load, with the standard derating: capacity drops to about 25% of the vertical rating at 45 degrees, the maximum acceptable angle. Alloy steel is typically supplied plain or coated; protect against corrosion in damp or outdoor use, or choose galvanized or stainless where rust is a concern. Always apply the manufacturer's angle derating, ensure the shoulder is flush, and inspect before each lift.
Why choose 8620 alloy steel shoulder pattern eye bolts
- Alloy strength: 8620 is strong and tough for demanding lifts.
- Angular and vertical lifts: shoulder handles side loads when seated flush.
- Forged grade: suited to heavy industrial loads.
- Reliable core: resists deformation under load.
Common applications for 8620 shoulder pattern eye bolts
- Heavy angular and vertical lifts
- Bridle slings and multi-point picks
- Industrial machinery lifting points
- Demanding rigging with possible side loads

8620 Alloy 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.
What is 8620 alloy steel?
A case-hardening alloy steel with a strong, tough core, commonly forged for lifting hardware that must carry heavy loads reliably.
Does the shoulder need to be flush?
Yes. The shoulder must seat completely flush against the load surface to function safely under angular loads.
