Description
UNF, 3/4″, Hexagon Head Bolts, High Tensile (5/ 8.8), Zinc/ BZP/ Cr3, DIN 931
UNF 3/4″, 16 T. P. I (Threads Per Inch)
Fixabal sells all lengths of 3/4″ UNF Bolts(PT-Partially Threaded) and Sets (FT-Fully threaded).
Bolt vs Set
A Hex Bolt is 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.
These bolts have threads as long as their diameters x 2.5 as a rule of thumb (please ask for exact measurement if it’s crucial). As the bolt length gets longer the plain shank gets longer and the threaded part stays the same.
If the size you need isn’t shown, please make an inquiry.

High Tensile, Bolt, 5 Grade Steel (8.8)
UNC and UNF high tensile standard is marked with an, ‘5’. This is comparable with, High Tensile – 8.8.
Bolt vs Set
A HexBolt(Part Plain Shank Bolt)is 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.
Bolt vs Screw
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). There are exceptions to the rules!
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.
