The bolt and sleeve assembly maximizes performance in joints that must accommodate expansion and contraction due to creep and in-service load relaxation.
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 design of the bolt and sleeve assembly maximizes fastening performance in these applications while minimizing in-place costs. 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. |
