Frequently Asked Questions (FAQs)

1. What are T-bolts used for?

T-bolts are threaded fasteners used to securely fasten two or more objects together. They have a unique design with a head that has two wings on either side. These wings allow the T-bolt to be tightened securely when inserted into a pre-drilled hole, making them ideal for various applications where strong, reliable fastening is required.

2. How strong are T-bolts?

T-bolts are generally stronger than T-slot nuts and hex-head cap screws. For example, a heavy-duty T-slot nut with an M12 bolt can support up to 10,000 N (about 1 imperial ton at rest). This strength makes T-bolts a reliable choice for applications that require robust fastening and secure connections.

3. What do T-bolts look like?

T-bolts have a distinct appearance that sets them apart from other bolts. They typically have a flat, straight head that resembles the top of a letter 'T', hence the name. The upper part of the shank is unthreaded, while the lower section is threaded. This unique design allows for easy insertion and secure tightening when used in conjunction with a pre-drilled hole.

4. What is a T-slot bolt?

A T-slot bolt is a type of bolt commonly used in machine tables. It is designed to protect machine table slots and provide increased bearing surface. T-slot bolts have a finished machined head that offers at least 50% more bearing surface under the table slot compared to T-bolts. They are known for their durability and wear resistance, making them suitable for various applications.
