ROLLED THREADS Are more accurate than machined threads
LASER-ETCHED MARKING Ensures size identification won’t wear off
Product Information — Tap Point Styles PLUG
ff General-purpose tap with 3–5 chamfered threads ff Used when there is sufficient room on a blind hole and tapping to the bottom is not required
TAPER
ff 8–10 chamfered threads at the tip are ideal for starting threads in tough materials ff Longest chamfer of all three types ff Commonly used in thru-holes and with materials where a guide is necessary ff Requires less torque due to more working teeth
Note: Tap and die size is indicated by two numbers. The first number represents the diameter of the screw or bolt. The second number represents threads per inch. The letters after the tap size indicate particular screw or bolt standard: NC = National Coarse UNC = Unified National Coarse NF = National Fine UNF = Unified National Fine NS = National Special NEF = National Extra Fine NPT = National Pipe Taper BSP = British Standard Pipe ISO = International Thread Standard (metric) Example: A 1/4–20 NC tap will cut 1/4 In. outside diameter with 20 threads per inch for a National Coarse-type screw.
BOTTOMING
ff Used after the threads have been started ff 1–3 chamfered threads at the tip are enough to start the hole and taps all the way to the bottom
