Crosby Eye Bolts
The shoulder on a Crosby G-414 eye bolt is not a cosmetic feature, it's what makes the difference between an eye bolt rated for angular loading and one that's only good for straight pulls. Riggers who know the G-414 know the shoulder designation, and they know why it matters when the sling angle isn't vertical.

About Crosby Eye Bolts
Crosby G-414 forged eye bolts are the standard reference for tapped-hole lift points in North American industrial rigging. The G-414 is a shouldered eye bolt, the shoulder seats against the load surface when the bolt is torqued in, providing a bearing surface that allows the eye to take angular loading within rated limits.
Plain-shank eye bolts without a shoulder are rated for in-line loading only. Any angular pull on a plain-shank eye bolt reduces capacity below the stamped WLL and introduces a bending moment on the shank. The G-414's shoulder design distributes that angular load through the shoulder-to-surface contact rather than through the shank.
All Crosby eye bolts in load-handling service fall under ASME B30.26-2015 (Rigging Hardware), which governs design factors, WLL marking, installation requirements, and inspection criteria.

Types of Crosby Eye Bolts
G-414 Shouldered Eye Bolts
The Crosby G-414 is the go-to forged eye bolt for applications requiring both in-line and angular loading capability. The shoulder seats against the load surface to distribute angular forces. Available in UNC thread sizes from 1/4" through 3" and metric equivalents. Forged carbon steel, self-colored or hot-dip galvanized depending on model.
Nut Eye Bolts
Nut eye bolts use a nut engagement rather than a threaded shank. They're used where the application requires the eye to pass through a hole and be secured from the other side. Crosby nut eye bolt designs maintain the shouldered feature to preserve angular load capacity where the bearing surface geometry allows.
Stainless Steel Eye Bolts
Stainless steel eye bolts are specified for corrosive environments, marine hardware, chemical processing, food and beverage installations. Crosby stainless eye bolts follow the same shouldered design geometry as the G-414 carbon steel series.
Crosby Eye Bolt Sizes and Working Load Limits
Crosby G-414 shouldered eye bolts cover thread sizes from 1/4" through 3" UNC and equivalent metric sizes. WLL varies by thread size and load angle, in-line WLL is higher than angular WLL at the same thread size. Crosby's manufacturer documentation provides the angular derating table for each bolt size.
Materials :
- G-414: Forged carbon steel, self-colored or hot-dip galvanized.
- Stainless models: Forged 304 or 316 stainless.
Marking :
- WLL and thread size on the eye body per ASME B30.26-2015 (Rigging Hardware).
- Manufacturer identification.
Why Crosby for Eye Bolts
The G-414's shouldered design is what riggers and engineers specify when the lift involves an angular sling pull. The shoulder-to-surface bearing area is the mechanism that allows the rated angular capacity, without that feature, an eye bolt is only good for straight-down loads.
Crosby's forging process and alloy steel sourcing back the G-414 with the same traceability that applies to their shackle and hardware lines. WLL markings are on the eye body, and the bolt ships with Crosby catalog data that includes angular derating values by thread size.
Holloway Houston also offers rigging inspection services. Our qualified inspectors examine eye bolts, hoist rings, and hardware per ASME B30.26-2015 (Rigging Hardware) and OSHA standards.

Eye Bolt Safety and Awareness
Eye bolts in load-handling service fall under ASME B30.26-2015 (Rigging Hardware). OSHA 1926.251 references eye bolts as load-handling equipment in jobsite use.
Key awareness points for eye bolts in service:
- Per ASME B30.26-2015 (Rigging Hardware), eye bolts are marked with WLL and size. A plain-shank eye bolt (without shoulder) is rated for in-line loading only, angular loading on a plain-shank eye bolt degrades capacity below the marked WLL.
- Crosby G-414 shouldered eye bolts carry angular load ratings that derate with increasing load angle. The angular derating table is in Crosby's manufacturer documentation and applies to properly seated, fully torqued installation.
- Eye bolt installation requires the shoulder to be fully seated against the load surface. A gap between the shoulder and the surface indicates the bolt is not fully engaged and the angular capacity rating does not apply.
- Pre-use inspection covers the eye for cracks or deformation, the shank thread condition, and the shoulder seating against the load surface.
Frequently Asked Questions
A shouldered eye bolt has a collar at the base of the shank that seats against the load surface. That shoulder bearing area distributes angular load forces through the surface contact rather than through the shank alone, allowing the eye bolt to carry rated capacity at specified sling angles. A plain-shank eye bolt has no shoulder and is rated for in-line (vertical) loading only, any angular pull imposes a bending moment on the shank and degrades capacity significantly.
The Crosby G-414 is a forged carbon steel shouldered eye bolt for tapped-hole lift points. It is rated for in-line and angular loading when properly installed with the shoulder fully seated. WLL is marked on the eye body per ASME B30.26-2015 (Rigging Hardware). Available in UNC thread sizes from 1/4" through 3" and metric equivalents.
ASME B30.26-2015 (Rigging Hardware) covers eye bolts in load-handling service, including design factors, WLL marking, and inspection requirements. Crosby's manufacturer documentation provides angular derating values and installation torque specifications.
