Available base and top coatings for ASTM/ASME Fasteners

See table below for all possible base coatings

Base Coat	Note
Electro Zinc plated (Zn)	Minimal against corrosion, suitable for inside. Easy torque.
Zinc-Nickel (Zn-Ni)	Excellent against corrosion, suitable for outside. Easy torque.
Hot Dip Galvanized, HDG (Zn)	Good against corrosion, suitable for outside. Uneasy torque.
GEOMET 500 (Zn-Al)	Good against corrosion, suitable for outside. Easy torque.

UNC Thread Chart

The Unified Thread Standars (UTS) defines a standard thread form and series along with allowances, tolerances and designations for screw threads, commonly used in energy, petrochemical and offshore industries. It is the main standard for bolts, nuts and other threaded fasteners.

UNC – Unified National Coarse thread. has the same 60° profile as the ISO metric screw thread, but the dimensions of the outer diameter were choses as an inch value.
UNF – Unified National Fine thread.

Diameter size	Thread Form & Pitch
5/16"	18 UNC
3/8”	16 UNC
7/16”	14 UNC
1/2”	13 UNC
5/8”	11 UNC
3/4”	10 UNC
7/8”	9 UNC
1”	8 UN
Bigger than 1″	8 UN
