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.
- 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:
| Direction
of Pull |
Adjusted
Working Load |
| 45
degrees |
30% of
rated working load |
| 90
degrees |
25% of
rated working load |
- Never undercut eye bolt to seat shoulder
against the load.
- Always countersink receiving hole or use
washers to seat shoulder.
- Always screw eye bolt down completely for
proper seating.
- Always tighten nuts securely against
the load.

 WARNING |
- Loads
may slip or fall if proper eye bolt assembly and lifting procedures
are not used.
- A
falling load can seriously injure or kill.
- Read
and understand both sides of these instructions, and follow
all eye bolt safety information
presented here.
- Read,
understand, and follow information in diagrams
and charts below before using eye bolt assemblies.

Shoulder Nut Eye Bolt ---
Installation for Angular Loading |
| IN - LINE 
|
- The threaded shank must protrude through the load
sufficiently to allow full engagement of the nut.
|
- If the eye bolt protrudes so far through the load that the
nut cannot be tightened securely against the load, use properly sized washers to take up
the excess space BETWEEN THE NUT AND THE LOAD.
|
- Thickness of spacers must exceed this distance between the
bottom of the load and the last thread of the eye bolt.
|
|
- Place washers or spacers between nut and load so that when
the nut is tightened securely, the shoulder is secured flush against the load
surface.
