T-nuts, also known as tee nuts or blind nuts, are specialized fasteners used in woodworking, metalworking, and other applications where a threaded insert is needed. They are designed to create a strong and reusable female thread in materials like wood, plastic, or composite boards. Below is a detailed description of T-nuts:
Key Features:
-
Shape:
T-nuts are typically flat, disc-shaped metal inserts with a threaded barrel extending from the center. -
Flange Design:
They have a flange at the base, often with prongs or teeth that embed into the material for a secure hold. Some T-nuts have smooth flanges for non-wood applications. -
Threaded Barrel:
The central barrel is internally threaded, allowing for the attachment of bolts or machine screws. -
Material:
T-nuts are commonly made from steel, stainless steel, or brass, depending on the intended application. Steel T-nuts may have zinc or black oxide coatings for corrosion resistance. -
Sizes:
They are available in various thread sizes (e.g., M4, M6, 1/4″-20) and barrel lengths to suit different material thicknesses.
Applications:
-
Woodworking:
Used to secure components such as furniture parts, knobs, and handles by creating a strong threaded connection in wooden surfaces. -
Metalworking:
Embedded into softer metals or composite materials to provide a durable thread. -
Rock Climbing Walls:
Commonly used to attach climbing holds securely to plywood or other wall panels. -
Fixtures and Machinery:
Ideal for joining and assembling mechanical components that require frequent disassembly.
