Greenfield M16x2 Straight Flute Hand Tap

The Greenfield Threading 313524 is a straight-flute hand tap designed for creating metric M16x2 threads. It is made from high-speed steel with a bright uncoated finish and features three flutes. This tool suits machinists and maintenance technicians who need to cut precise internal threads by hand.

Suited for metric M16x2 through-hole work

This tap suits users cutting new threads in through-holes where chip evacuation ahead of the tool is preferred. It is not for blind-hole applications where chips must be pulled upward, nor for left-hand thread requirements. Builders needing a bottoming or taper lead, or a different thread limit, should select another tool.

Thread limit D11 and 6H class of fit

The tap is manufactured to a D11 thread limit with a 6H class of fit, which determines the allowance and tolerance of the finished thread. This single specification decides whether the produced thread meets the engineering drawing requirements for the assembly. Verify the required limit and fit before purchase.

Questions about this item

What drill diameter does the M16x2 tap require for a 75 percent thread?

Use a 14.00 mm drill to achieve a 75 percent thread before tapping the M16x2 hole.

How do you start the 313524 tap straight in the hole?

Apply steady axial pressure while turning the square drive clockwise; the plug chamfer guides the first threads so the tap does not walk.

When should the 3-flute high-speed steel tap be replaced?

Replace it when the cutting edges dull enough to produce rough threads or require excessive torque on the M16x2 size.
