The Crosby G-277 Shoulder Nut Eye Bolts are premium forged lifting points engineered for secure through-bolted lifting applications. Each unit is forged from quenched and tempered steel, hot-dip galvanized for corrosion protection, and supplied with a heavy hex nut for proper clamping and seating. Designed for both in-line and angular loading (with capacity reduction), the G-277 meets or exceeds all ASME B30.26 requirements for identification, ductility, design factor, and proof load performance.
Key Features
Forged steel construction, quenched and tempered for strength and durability
Supplied complete with hot-dip galvanized heavy hex nut
5:1 design factor; proof tested to 2× the Working Load Limit (WLL)
Fatigue rated to 1.5× WLL at 20,000 cycles
Meets ASME B30.26 and Crosby’s internal fatigue, impact, and traceability standards
Hot-dip galvanized after threading for full corrosion protection
Rated for in-line loading; angular use permitted with reduced capacity
Pro Tip: Unlike the S-279 Machinery Eye Bolts, the G-277 includes a heavy hex nut and is designed for use in through-hole applications. Ensure the shank protrudes completely through the load so the nut can seat flush against the surface. If excess thread extends beyond the nut, use properly sized washers or spacers to achieve full shoulder contact before lifting.
Working Load Limits & Size Range
Thread sizes from 5/16" to 1-1/2"
Working Load Limits from 1,200 lbs to 24,000 lbs
All threads are UNC and hot-dip galvanized
Safety & Installation Notes
Rated capacities apply to in-line pulls only. Reduce WLL for angular lifts:
15° = 80% of WLL
30° = 65% of WLL
45° = 30% of WLL
90° = 25% of WLL
Always seat the shoulder flush against the load surface; never undercut the shoulder to achieve fit.
Inspect threads and eye for wear, bending, or elongation before each use.
For two-nut assemblies (when shank protrusion ≤ one bolt diameter), tighten both securely against the load.
Do not reeve slings through multiple eye bolts; it changes load direction and reduces capacity.
Typical Applications
Machinery and equipment lifting
Through-bolted hoisting points on fabricated structures
OEM mounting and maintenance lifts
Important: For angular lifting or side-pull applications, always apply rated capacity reductions as listed above. Maintain clean, undamaged threads, and ensure all assemblies are tightened securely before use. Refer to Crosby’s official warning and application charts for complete safety guidance.
