The A to X of insert nuts

There are a lot of insert nuts to choose from. The team at JET PRESS is always on hand to give you the best possible advice. In the meantime, here is a quick guide to some of the options available.

A Type or B Type are suitable for lightweight applications. They tap quickly and easily into a pre-drilled hole. External barbs prevent spinning and offer a good level of pull-out resistance, particularly in hard wood and plywood. Type A Inserts are unheaded so they can be embedded in the timber for a flush fit. Type B has a flanged head which prevents pull-through when bolted from the underside.

Screw-in Type D and Type E Insert Nuts offer a greater degree of hold-in and a higher resistance to vibration, thanks to the external, self-tapping thread. The hex head makes fitting quick, accurate and easy using a hexagon driver or Allen key. This makes them well suited for use in soft woods and chipboard. The flange on the D Type ensures that the insert is screwed tightly up to the timber surface whilst the Type E can be fully embedded within the pre-drilled hole

Type I inserts offer a neat finish where the head is visible. Large flanged inserts spread load across a larger surface area on heavy duty assemblies. Type P inserts ensure a highpull-out resistance and expanding brass, Type X inserts grip tighter as the bolt is screwed in and serrated.

There’s a lot to think about when selecting the correct Insert Nut for your job. The thread size and length of insert required are often determined by the fixings being used and the timber thickness. And you have to factor in the forces in play in the joint where the Insert Nut is to be used.
