T nuts

T Nuts Details

T-nut, T nut, or tee nut (also known as a blind nut, which can however also refer to as a rivet nut or an insert nut, and likewise drive-in nut is a type of nut used to fasten a wood, particle, or composite materials workpiece, leaving a flush surface.T nuts have T slot nuts and weld nuts, two types.

T-nuts have a long, thin body and a flange at one end, so they look like a T in profile. The prongs on the flanges sink into the wood to hold it more securely. The flanges of T-nuts often have hooks or serrations on the prongs that dig into a wooden workpiece as the bolt is tightened from the opposite side of the piece, providing better retention.
In 1969, the first four-prong T-nut with an eight-sided base was patented. Unlike standard round base T-nuts, eight-sided T-nuts can be fed efficiently and reliably via machine. The eight-sided T-nut base has become the standard configuration for T-nuts inserted by machine

Frequently Asked Questions

Use a hammer to get the t-nuts completely flush and seated. Make sure they are straight and flush with the surface of the plywood. There are 288 in one 4×8 sheet of plywood. Your arm will bet tired but stick with it and get them all seated correctly.

What is this? Since the only way the T-nut can come out of the wood is to be pulled through it, it is an incredibly strong fastener. T-Nuts installed into soft plywood have a pull out strength of 1378 pounds, while those installed in hardwood plywood have a pull out strength of 1850 pounds.

A T-slot nut is used with a threaded clamp to position and secure pieces being worked on in a workshop. The T-slot nut slides along a T-slot track, which is set in workbench or table for a router, drill press, or bandsaw

Tee nut size refers to its nominal thread diameter. Typically, sizes range from about #6 to 3/8″. Sizes less than 1/4″ appear as a number size (the larger the number the larger the size) while sizes that are 1/4″ and larger are specified in inches, usually fractional rather than decimal.
