Regular Nut Eye Bolt G-291	Shoulder nut Eye Bolt G-277	Machiner Eye Bolt S-279/ M-279

Important Safety Information -Read & Follow

Inspection/Maintenance Safety:

•Always inspect eye bolt before use

•Never use eye bolt that shows signs of wear or damage.

•Never use eye bolt if eye or shank is bent or elongated.

•Always be sure threads on shank and receiving holes are clean.

•Never machine, grind, or cut eye bolt.

Assembly Safety:

•Never exceed load limits specified in Table I & Table 2.

•Never use regular nut eye bolts for angular lifts.

•Always use shoulder nut eye bolts (or machinery eye bolts) for angular lifts.

•For angular lifts, adjust working load as follows:

•Never undercut eye bolt to seat shoulder against the load.

•Always countersink receiving hole or use washer with sufficient I.D. to seat shoulder.

•Always screw eye bolt down completely for proper seating.

•Always tighten nuts securely against the load.

Shoulder Nut Eye Bolt - Installation for Angular Loading

IMPORTANT - Read and understand these instructions before using eye bolts. Regular Nut & Shoulder Nut Eye Bolt - Installation for In-line Loading

Operating Safety

•Always stand clear of load.

•Always lift load with steady, even pull - do not jerk.

•Always apply load to eye bolt in the plane of the eye - not at an angle.

•Never exceed the capacity of the eye bolt-see Table I & 2.

•When using lifting slings of two or more legs, make sure the loads in the legs are calculated using the angle from the vertical to the leg and properly size the shoulder nut or machinery eye bolt for the angular load.

Machinery Eye Bolt - Installation for In-line & Angular Loading

These eye bolts are primarily intended to be installed into tapped holes.

1. After the loads on the eye bolts have been calculated, select the proper size eye bolt for the job.

For angular lifts, adjust working load as follows:

2. Drill and tap the load to the correct sizes to a minimum depth of one-half the eye bolt size beyond the shank length of the machinery eye bolt.

3. Thread the eye bolt into the load until the shoulder is flush and securely tightened against the load.

4. If the plane of the machinery eye bolt is not aligned with the sling line, estimate the amount of unthreading rotation necessary to align the plane of the eye properly. Remove the machinery eye bolt from the load and add shims (washers) of proper thickness to adjust the angle of the plane of the eye to match the sling line. Use Table 3 to estimate the required shim thickness for the amount of unthreading rotation required.
