Expansion Bolt is also called Fixed Anchor Bolt. Expansion bolts can be used to secure heavy objects to walls or floors. Can handle vertical and horizontal loads.

The expansion mechanism may be a sleeve, slotted shell, slotted stud, or wedge assembly which is actuated by a tapered cone, tapered plug, nail, bolt, or screw depending upon the anchor style.

It is a penetration type casing anchor bolt. When the nut and bolt are tightened, the conical head of the anchor bolt is pulled into the expansion casing, and the expansion sleeve expands and presses on the borehole wall to play a fixed role. The compression of the expansion mechanism against the wall of the drilled hole allows the anchor to transfer the load to the base material. Anchors which are expanded by tightening a bolt or nut are considered to be torque controlled while those that are actuated by driving a nail or plug are considered to be deformation controlled. A deformation controlled anchor can develop a higher initial compression force when compared to a torque controlled anchor. Compression anchors may also be pre-expanded and/or used in conjunction with a drive nail. The expansion mechanism on an anchor of this style is actuated as it is compressed during the driving operation into the anchor hole.
