S S E M B L Y

Features
• Cold formed bolt with roll-formed threads
• Captivated sliding sleeve with resilient grommet
• Fastener/sleeve meets strength levels up to P.C.10.9
• Custom-engineered to desired compression load and
distance requirements
• Manufacturing method minimizes damage to grommet

Acument® Global Technologies
maximizes performance in joints that
must accommodate expansion and
contraction due to creep and in-service
load relaxation.

Benefits
• Accommodates vertical movement of joint components
caused by in-service conditions, including load relaxation and
thermal expansion
• Can be used with nonparallel joint surfaces
• Minimizes damage to the top surface of the joint
• Accommodates tolerance variations in components
• Engineering changes in sleeve length easily and quickly
accommodated
• No added costs for tooling changes for varying sleeve lengths
• No special tooling required for installation

D

Thermal expansion, creep and material relaxation cause
application materials to expand or contract. These dimensional
changes can result in the loss of clamp in the joint members. A
fastener that can accommodate these changes while
maintaining the integrity of the application is needed.

The sliding sleeve features a grommet that can expand or
contract as needed to accommodate changes in the
application material. The sleeve is not crimped into place but
instead is held in place by the washer. This maximizes
fastener strength.
The foot increases
contact area to
minimize potential
embedment at the
surface of the
tapped hole, while
the resilient
grommet protects
the top surface of
the joint.
The sliding action
of the sleeve allows
faster and easier
alignment into the
tapped hole.
