BOHLT/bəʊlt/

A bolt here is a metal pin with a thread, used with a nut to fasten things together: a steel bolt; bolt and nut. Screw is a close twin, often wood; pin is unthreaded. Give the bolt size in the DT spec, then the torque if asked. Mix-up: bolt vs bold; the “run away” verb and the door-bolt sense — use those only if the source names flight or a lock; do not write bolt for a nail.

Meaning

A metal pin with a thread, used with a nut to fasten things together.

Examples

• “Give the bolt size in the DT spec, then the torque if asked, not a “run for it” caption.”
