1988, Michael Ross, “The Electric Guitar as an Acoustic Instrument”, in Getting Great Guitar Sounds: A Non-technical Approach to Shaping Your Personal Sound, Milwaukee, Wis.: Hal Leonard Books, ISBN 978-0-88188-596-5, page 18:
- Some guitars have the neck glued to the body (Les Pauls), some are bolted on (Fenders), and in some the neck is part of one piece of wood that extends through the body (Jackson). The theory of the neck through the body design is that if the pickups, bridge, and the strings (from tuners to tailpiece) are mounted on the same piece of wood, sustain will be greatly enhanced. In practice, a well joined glue-on and a properly fitted bolt-on will sustain just as well.
1998, John Bell, “Mechanisms for Cross-fertilisation of Administrative Law in Europe”, in Jack Beatson and Takis Tridimas, editors, New Directions in European Public Law, Oxford: Hart Publishing, ISBN 978-1-901362-24-4, page 147:
- I would draw a distinction between transplants and cross-fertilisation. […] Cross-fertilisation implies a different, more indirect process. It implies that an external stimulus promotes an evolution within the receiving legal system. The evolution involves an internal adaptation by the receiving legal system in its own way. The new development is a distinctive but organic product of that system rather than a bolt-on.

2017 May 13, Barney Ronay, “Antonio Conte’s brilliance has turned Chelsea’s pop-up team into champions”, in The Guardian, London, archived from the original on 9 September 2017:
- Friday night's crowning victory at The Hawthorns was the 25th in 30 league matches since Antonio Conte's decisive re-gearing of his team in September, the tactical switches that have coaxed such a thrilling run from this team of bolt-ons and upcycled squad players, most notably Victor Moses, who was dredged out of the laundry bin in the autumn to become a key part of the title surge.
- (figuratively) A functionality or service that can be added to an existing arrangement or plan (for example, a mobile telephone subscription).

- [I]f an innovation has reached the maturity stage of the product life-cycle, then perhaps its functionality will be developed to provide a ‘bolt-on’, with the core of the innovation remaining essentially the same. A classic example of a sustained innovation is the mobile phone, where functionality is increased by adding on extra capabilities, such as video, Internet acss, GPS tracking systems, music, and email.

- [T]he first model of this now most famous line of related types, the [Gibson] Les Paul also appeared in 1952, […] The trapeze style tailpiece and combined bar bridge was also fitted, although this gave way to a bolt-on bar bridge by 1953.

- This week we take a close look at four top contenders in the multitasking arena […] All the multitasking systems available for microcomputers today fall into one of two distinct categories: "bolt-on" multitaskers, which add multitasking to an operating system (DOS, for example) that originally executed one task at a time; and "built-in" multitaskers, which are part of the operating system by design.
