Frequently Asked Questions (FAQs)

1. What is the use of T-slot nut?

T-slot nuts are used in workshops with a threaded clamp to position and secure pieces being worked on. They slide along a T-slot track, which is set in a workbench or table for tools like a router, drill press, or bandsaw.

2. What is the difference between a T bolt and a T nut?

The main difference between a T bolt and a T nut is that when the nut is tightened, the stud in the T nut may rotate, producing a jacking force pushing up on the T slots. With a T bolt, the tightening force is focused on compressing the metal above the slot.

3. What size are Tee Nuts?

The size of Tee nuts refers to their nominal thread diameter. They typically range in size from #6 to 3/8". Sizes smaller than 1/4" are indicated by a number, with larger numbers representing larger sizes. Sizes 1/4" and larger are specified in inches, usually in fractions.

4. What are the advantages of T bolts?

T bolts are ideal tighteners because they can prevent objects from loosening due to vibrations. They effectively manage vibrations and provide tight fixations, ensuring that objects stay securely in place during work.

5. What is the difference between T slot and V slot?

T-slot and V-slot are two common types of aluminum extrusion profiles. While they are sometimes used interchangeably, they are not exactly the same. T-slot profiles have a 'T' shaped groove on each side, while V-slot profiles have a beveled edge.

6. How do you measure a T-slot nut?

To measure a T-slot nut, measure the width at the top of the T-slot. This dimension is used to specify T-slot nuts and clamping kits. For example, if the measurement at the top is 0.468 inches, a 7/16" (0.438") T-slot nut or clamping kit should be used.

7. Can you hammer in tee nuts?

Yes, tee nuts can be installed by drilling a hole slightly wider than the diameter of the barrel of the nut and then pushing or lightly tapping the nut with a hammer. This causes the prongs of the nut to dig into the material, securing it in place.

8. How much weight can a tee nut hold?

The weight that a tee nut can hold depends on its size and material. For example, a 3/8-16 4-prong stainless steel tee nut can hold up to 1426 pounds of force when properly installed and seated in a material like a 3/4" ACX plywood panel.

9. What are the different types of tee nuts?

There are two broad types of tee nuts - pronged tee nuts and weld nuts. Pronged tee nuts are commonly used with wood and have prongs that secure them into a predrilled hole. Weld nuts, as the name suggests, are designed to be welded onto a surface.
