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.

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).
