The uses of Threaded Inserts are not restricted to just machines and tools but also for other exciting purposes like fixing up your musical instruments and some daily utilities. In guitars, mainly these threaded inserts are used to attach the `bolt-on` neck to the instrument or the bass and the most common method of doing this involves 8 screws in total. It is very easy and simple to fix them on the instrument and for people who find this difficult, there is a manual attached with each pack. These threaded inserts can be bought straight from the dealers or can be ordered online to this provider TAPPEX, with the correct specifications.
