(a) Headless tapered bolt

(b) Tap-bolt or cap screw

(c) T-headed bolt

(d) Countersunk-headed bolt

I got this question during a job interview.

This is a very interesting question from Bolts in chapter Screw Threads & Screwed Fastening of Engineering Drawing

Answer 1

Correct choice is (c) T-headed bolt

To explain I would say: This bolt is used in machine-tool tables in which T-slots are cut to accommodate the T-heads. This is often made use of in gland and stuffing box arrangement in boiler mountings such as stop valve, feed-check valve etc.
