It's an obvious misnomer.

bolt
(bōlt)n.
1. A bar made of wood or metal that slides into a socket and is used to fasten doors and gates.
2. A metal bar or rod in the mechanism of a lock that is thrown or withdrawn by turning the key.

3. A fastener consisting of a threaded pin or rod with a head at one end, designed to be inserted through holes in assembled parts and secured by a mated nut that is tightened by applying torque.


screw

(skro͞o)n.
1.
a. A cylindrical rod incised with one or more helical or advancing spiral threads, as a lead screw or worm screw.
b. The tapped collar or socket that receives this rod.

2. A metal pin with incised threads and a broad slotted head that can be driven as a fastener by turning with a screwdriver, especially:
a. A tapered and pointed wood screw.

The Machinery Hanbook is a good reference accepted by engineers as an authoritative guide. I don't have my copy handy, so I can't quote it directly, but this is what I think it says about screws and bolts.

A bolt is an externally threaded fastener designed for insertion through holes in assembled parts, and is normally intended to be tightened or released by torquing a nut.

A screw is an externally threaded fastener capable of being inserted into holes in assembled parts, of mating with a preformed internal thread or forming its own thread and of being tightened and released by torquing the head.

Thus, "bolt on" is not an accurate term for wood screws, or machine screws used to attach a neck.
 
"Real" bolted joints as opposed to wood screw[edit]
The term is usually a misnomer, introduced mostly by Fender whose guitars traditionally had what is called bolt-on necks. Real bolted joints (i.e., using bolt coupled with a nut) exist—particularly in acoustic guitars—but are less common in electric guitars.[3] However, at least one aftermarket manufacturer[4] offers a replacement for Fender neckplates and screws that uses captive inserts—embedded in the guitar body by means of an external self-tapping thread — and M4 machine screws. The maker claims this permits a higher fastening torque than ordinary wood screws, and hence a better coupling between neck and body.
