A sleeve anchor, also known as an expansion bolt, is constructed of a lead sleeve, a nut, a washer and a threaded stud. Similar to strike anchors, sleeve anchors are extensively used where traditional threaded fastening is not permitted, including concrete, brick, block and the like. During installation, the metal cone is pulled into the lead sleeve and forcing the lead sleeve outward to fill all the pores of base material. In this way, the sleeve anchor are locked in the place firmly, regardless of light to heavy loads.

A zinc plated sleeve anchor is composed of a nut, a washer, lead sleeve and threaded stud.


A nut & washer - Screwed into the stud, a washer and a nut are used to urge the cone-shaped head of the threaded stud in the sleeve.

Lead sleeve - With four equally spaced slots, this expansive split sleeve is butted against the small diameter of the cone-shaped end before installation.

Threaded stud - Located inside of the lead sleeve, this threaded stud features an outwardly flared cone-shaped end.
