These screw-mount nuts are often used to attach glides and levels to wood.

The flange distributes the load over a large area and reduces stress where the nut meets the material surface.

Tri-groove nuts are narrower than sloped and drilled spanner nuts to fit in tight spaces. Install with a tri-groove socket bit and either a drive handle or an open-end wrench.

The flange keeps these inserts from being pulled through a hole and provides a load bearing surface.

Assortments include various sizes of tapping inserts for softwood.

An open end allows long screws and bolts to pass through the insert.

Also known as caulk-in anchors, these stay secure when there's not much material to hold.

Often referred to as four-way expansion anchors, these expand in four directions to resist loosening from vibration.

Also known as drive rivets, install by hammering the screw into the body. Unthread the screw to remove.

Connect T‐slotted rails and reinforce joints for structural stability.
