Hex/ Allen Socket Countersunk Screw/ Bolts Description
Countersunk fasteners are designed to fit flush on the connecting surface when fully tightened. They are tightened and loosened with an allen/ hex key drive.
How to measure a countersunk fixing/ fastener
The length of a countersunk fixing/ fastener is always from tip to top.
Socket Countersunk Screws come as 'sets' and 'bolts'. The, ‘SET’, term is used to describe a fastener that is fully threaded. Over a certain length (around 2.5 x the diameter) the length the fastener will have a, 'shoulder,' or unthreaded area under the head (plain shank). This space of unthreaded area confirms that the fastener is now a bolt (socket countersunk bolt in this case) and is shouldered. Some people might simply call them socket allen bolts,' in association with the Allen, Hexagonal Key which is used to tighten and loosen the fastener. So, ‘Socket,’ refers to the hexagon shaped indentation found on the top of the fasteners’ head.
Measuring a Countersunk Socket Screw/ Bolt's Length
The length of a countersunk fixing/ fastener is always from tip to the top.

If the item was sent to your home, ask anyone else living there if they accepted the delivery. Please also check if the item has been left with a neighbour, or in your designated Safeplace if you have one.
If the item was sent to your work address, check with the post room and your colleagues to see if someone accepted the delivery.
If you bought the item online, check the shipping address was correct.
