    Hi, first of all I apologise if I posted this in the wrong section, I wasn't sure which category it would fall under. I had a door bolt installed on my bedroom door but it broke today. I need to get another door bolt but I have no clue which one to get.

    With the one I had previously. I had to use the handle and open it ever so slightly to get the door lock to actually fit into bolt hole.

    Also what is the difference between necked and straight door bolts?

    Measure the old one and buy a straight bolt of a similar size. Fit the bolt first and then align the keep, packing out with e.g. thin cardboard behind it so it all sits flush and the bolt is easy to use.

    Problem is actually other way round Rusty and Teabreak as OP said 'have to use handle and open door slightly to get lock to fit in bolt hole'

    As we would instantly know, either a thinner door has been fitted or frame stops sets too far back
    Need to either recess the keep or pack out the lock (easier than messing around with stops) to get all to align

    Would say bolt you have is around this size; (also available in brass)

    But simply measure outline on door, doesn't need to be exact but will be helpful as will cover old paint on door (and they do tend to come in set sizes)

    As for the need to open door slightly to line up bolt in keep, door has been set back slightly too far in frame
    Two options here - either cut around the keep on door frame and chop away a little timber to recess, like a mm or 2 (same amount as you need to bring door forward)

    Or as Mr Rusty suggested (but other way round) pack out lock with cardboard, screw through lock and card so both parts line up
    Card from back of an A4 pad works well :) (how do I know) :D

    A necked bolt would be used on other side of door with a hole being drilled into door stop for the cranked bolt to slip into, flat cover plate then neatens drilled hole
    You will see how your 'straight bolt' wouldn't work on other side of door as bolt would line up with very edge of door stop and you cant fit the keep supplied

    Anyway, easy job even with limited diy skills so good luck
