- 5 16-18 UNC Tap Drill: F (0. 2570) — ASME B1. 1
5 16-18 UNC is the Unified coarse thread for the 5 16 in (7 94 mm) diameter: 18 threads per inch, a pitch of 0 05556 in (1 411 mm), on a 60° profile ASME B1 1 lists it in the UNC series
- 5 16-18 UNC Thread Size Tap Drill | Great Lakes Shafts
5 16-18 UNC is a Unified National Coarse thread: 0 3125 in nominal major diameter and 18 threads per inch, a pitch of 0 0556 in from one crest to the next It is a 60° V-form thread The major diameter, 0 3125 in, is the outside of the external thread and the diameter a shaft end is turned to before the thread is cut
- 5 16-18 Bolt Size (UNC, drill, hex) - boltlab. io
5 16-18 UNC uses 0 3125in diameter, 18 TPI, and letter F tap drill in many charts Compare M8 equivalents below and use metric to imperial conversion
- UNC Thread Chart: 33 Sizes, Tap Drills Pitch Diameters
The threads are deep relative to the diameter, which makes them quick to assemble, tolerant of dirt, burrs and plating, and strong in soft materials such as cast iron and aluminium, where the nut thread is the weak part of the joint
- Unified Thread Standards: UNC UNF Size Charts Specifications
UNC threads according ANSI B1 1: Pitch is the distance between screw grooves and is commonly used with inch sized products and specified as threads per inch Lead is the linear travel the nut makes per one screw revolution The pitch and lead are equal Example - Typical designation of an UNC thread UNF threads ANSI B1 1:
- UNC Thread Chart
Use nominal diameter and TPI to identify the UNC designation, and use the calculated basic dimensions to understand the ideal thread geometry For manufacturing or inspection, continue to the governing ASME B1 1 class limits and the applicable product gaging requirements
