The Hexsert® provides a blind threaded insert with a hexagonal body, yielding high torque-to-turn and pull-out performance, particularly in soft metals.

The hexagonal section and bore improves torque-to-turn by up to 200% in sheet metal, compared to round-body inserts. Plus, the Hexsert® can be used in very thin materials (from 0.50mm [0.02"]) with quick and easy insertion.

Available in various platings and options, The Hexsert® can be used with hand tools, pneumatic tools, and fully automated machines to suit a wide range of assembly methods.

74290 tool for hexagonal hole production
The 74290 tool complements and extends the range of Avdel® hand tools for installing threaded inserts, by offering the capability of producing hexagonal holes for threaded Hexsert® inserts into materials where access is only possible from one side. The 74290 tool allows customers to benefit from the non-rotational properties of hexagonal inserts compared with round inserts. This is achieved by drilling a round hole, then inserting the 74290 tool and forming a hex hole.
