Proper Use of Forged Shoulder Eyebolt
General Hardware Information
4
Any hardware used in an overhead suspension application must be load rated for the intended use.
Generally, this type of hardware is available from rigging supply houses; industrial supply catalogs and
specialized rigging distributors. Local hardware stores do not usually stock these products. Hardware that
is intended for overhead suspension will comply with ASME B30.20 and will be manufactured under prod-
uct traceability controls. Compliant hardware will be referenced with a working load limit (WLL) and a
traceability code.
All SoundFactor Install loudspeakers include a rigging hardware kit (part# 229-00009-01) which includes
3 forged shoulder eyebolts and 3 washers. When installing these speakers, use hardware found in the kit
provided. For additional rigging components, consult with a professional rigging hardware supplier.
Sources for specialized rigging hardware may be found on page 11.
The JBL SoundFactor Install loudspeakers are supplied with three forged M10-1.5 x 35 mm shoulder eye-
bolts with appropriate ratings and certified standards compliance, for use in overhead suspension appli-
cations. To install the eyebolts into the provided threaded holes on the loudspeaker, first remove the fac-
tory installed, flat head machine screw using a 6 mm hex key wrench. The M10-1.5 threaded internal
brace is accessible once the flat head machine screw is removed. Deposit thread lock adhesive, follow-
ing the adhesive manufacturer's instructions, onto the threaded tip of the eyebolt. Install the forged shoul-
der eyebolt as a replacement for the machine screw, being careful not to cross-thread the fasteners.There
should be little resistance when installing any fastener. As a general rule for "soft surface" installations
such as a wooden surface, the suggested torque is achieved by installing the fastener until snug and then
rotating the fastener an additional 180 degrees (1/2 turn).
The load imposed on the eye of the eyebolt fastener must remain in the plane of the eye only. When any-
thing other than a straight-line pull is used, the provided forged, shoulder eyebolt load rating must be
adjusted as follows:
