What are Pad Eyes?
Pad eyes are low-profile anchors with a solid eye on a mounting base used to create a reliable tie-down or lifting point on equipment, vehicles, frames, and decks. They pair with shackles, hooks, or slings to secure loads where space is tight and a fixed, in-line pull is required. Our selection features USA-made pad eyes by Ken Forging.
When to Use Pad Eyes
- Fixed tie-downs on skids, trucks, machinery, and fabricated frames
- Marine and dock hardware attachment points on decks and rails
- Rigging pick points for controlled, in-line lifts with compatible shackles
- Permanent anchors in material handling and construction fixtures
Pad Eyes vs Hoist Rings
Choose a pad eye when you need a rugged, fixed anchor for straight pulls. For dynamic or angular lifts where the connection must pivot or swivel, use a rated hoist ring instead.
How to Select the Right Pad Eye
- Hole to pin fit: Match the pad eye hole to the shackle pin size so the pin sits snugly and rotates freely.
- Material & finish: Carbon steel for general duty; stainless for wet or corrosive environments; galvanized or zinc-plated options for added corrosion resistance.
- Mounting style: Weld-on for permanent structural anchors; bolt-on for removable or serviceable points (use proper fasteners and backing where required).
- Load direction: Plan for straight, in-line loading through the eye. If off-axis loading may occur, upgrade to a solution that accommodates angle or rotation.
- Size & capacity: Confirm Working Load Limit (WLL) meets or exceeds your required load with an appropriate safety factor.
Installation Tips
- Verify base thickness and grade are suitable for the rated load.
- For bolt-on installs, use properly sized fasteners, washers, and backing plates; torque to spec.
- For weld-on installs, follow qualified welding procedures and inspect welds before putting into service.
- After installation, confirm the shackle pin can rotate freely in the eye.
Inspection & Safety
- Inspect before each use for cracks, deformation, corrosion, or elongated holes.
- Use only within the stated WLL; avoid shock loading and side-loading.
- Replace any pad eye or shackle showing damage or excessive wear.

Frequently Asked Questions about Pad Eyes
-
What does a pad eye do?
It provides a compact anchor point for shackles, hooks, or slings, creating a secure tie-down or lifting point for in-line loads.
-
Are pad eyes rated for lifting?
Many are, when installed on suitable structure and used in-line within the published Working Load Limit. Always verify the device rating and installation method.
-
How do I size the hole to my shackle?
Choose a pad eye with a hole that closely matches the shackle pin diameter so the pin seats fully and rotates freely without excess play.
-
Can I use a pad eye for angled or rotating lifts?
Pad eyes are best for straight pulls. For angled or rotating lifts, use a swivel/hoist ring designed to maintain capacity at angle.
-
Weld-on or bolt-on pad eye?
Weld-on provides a permanent structural anchor when welded by qualified procedures. Bolt-on is preferred where serviceability or access beneath the mounting surface is needed.
-
How should I inspect pad eyes?
Look for cracks, distortion, elongated holes, corrosion, or weld defects; ensure the shackle pin seats and rotates properly; replace if any damage is found.
