T Nuts
T-nuts, also known as tee nuts or T-slot nuts, are a type of fastener named after their shape, namely how they look like a “T” when viewed from the side. The shape consists of a flat base with prongs or spikes protruding from the bottom and a threaded barrel on top. The threaded barrel is what allows for the attachment of bolts, screws, and threaded rods, providing a secure and adjustable connection point.
Frequently Asked Questions About T-Nuts
What are t-nuts used for?
T-nuts are frequently used in woodworking, cabinetry, and metalworking. They are designed to provide a threaded socket in materials to allow for the attachment of bolts or screws.
How are T-nuts installed?
T-nuts are installed via first inserting the prongs into pre-drilled holes or slots, and then hammering or pressing the T-nut into place. The prong’s grip on the material prevents the T-nut from rotating or loosening. T-slot tracks and extrusions are often installed alongside T-nuts, allowing for flexible positioning and installment of accessories (ie workbenches, machine tables, industrial equipment).
What is the difference between a 3-prong and 4-prong T-nut?
Other than the number of prongs, the main difference between these two types of T-nuts is the stability they provide. Due to having fewer prongs, 3-prong T-nuts provide less stability, but offer more flexibility. They also minimize the splitting of the mating surface, making them perfect for applications involving harder materials like metal to wood. 4-prong T-nuts provide a stronger grip and increased stability, and therefore are a great fit for heavy-duty fixtures.
What sizes are T-nuts available in?
AFT offers T-nuts in diameter-thread sizes ranging from #6-32 to 3/8”-16, as well as lengths ranging from 1/4” to 5/8”.
What materials and finishes are T-nuts available in?
T-nuts are available in steel (popular due to strength and durability), stainless steel (excellent corrosion resistance, used in outdoor furniture and food processing environments), brass (electrical conductivity and aesthetics, used in decorative fixtures and electrical enclosures), aluminum (lightweight, used in aerospace and automotive applications, as well as for aluminum extrusions). AFT offers T-nuts in plain finish, as well as Zinc or Zinc Cr+3 for extra corrosion resistance (popular with steel T-nuts).
