Hexagon Bolt

Bolt is the term used for a partially threaded fastener (part plain shank, bolt), with a hexagon shaped head, designed to be used with a nut and washer. 

Material:

A4 Stainless Steel (marine) also known as 316. Marine grade stainless has a very high resistance to corrosion

Thread

Metric Coarse Thread - measured in Millimetre (mm) units and were developed to simplify the imperial systems. Europe moved to this system but the Americans choose Imperial as their default. A coarse thread has less helical coils per mm and a fine one has more. Coarse is used for heavier loads and fine is used for lighter loads prone to vibrations.

Bolt Thread Length

The thread length of a shoulder bolt/ plain shank bolt tends to be 2.5 times the diameter of the fastener. Please ask for exact measurements if the shoulder is crucial.

Bolt vs Screw

A screw screws into something, a bolt joins several things together from both sides of materials joined. A screw is fully threaded from underneath the head and a bolt is partially threaded (has a part-plain shank)
