Hex Bolt vs Hex Set Screw
A HexBoltis the term used for apartially threadedfastener, with a hexagon head; designed to be used with a nut and washer. A HexSet (Screw Bolt)is the same, except it isfully threaded.A screw screws into something, a bolt joinsseveral 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/ shoulder).
UNIFIED THREAD STANDARDS
Thread standards agreed upon by standard bodies of Canada, the United Kingdom, and the United States.
Unified National (UN)thread form with a rounded root contour, applies only to external threads. (The UN thread form has a flat, or optionally, a rounded root contour.) The majority of fasteners with a Unified thread form (UNC, UNF) have a rounded root contour i.e. are UNR threads.
Unified National Fine (UNF)is a thread form with a 60 degree flank angle rounded roots and flat crests. For a given diameter it has a smaller thread pitch than an equivalent diameter UNC thread.
