TITANIUM COATINGS

Wrentham can supply punches with two types of wear resistant Titanium Nitride coating, Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD). The properties of Titanium Nitride that make it useful are its hardness and low coefficient of friction. When applied to punches the coating acts as a chemical and thermal barrier between the punch and the screw. The low coefficient of friction helps to prevent galling and metal pick-up, resulting in increased punch life, improved surface finish, and minimized downtime from fewer setups. Wrentham can quote other special coating requirements upon request.

TITANIUM NITRIDE PLUS

Wrentham Tool Products can also supply punches and pins with Titanium Nitride Plus coating. These punches are highly polished prior to CVD or PVD coating. This results in an increase of benefits as specified above.

CALIBRATION

Wrentham Tool can inspect and certify your penetration gages, plug gages, ring gages, and test blocks. We certify to known standards applicable for the various recess types: ANSI/ASME B.18.6.4-1981, Screw Research Assoc. and Phillips® Screw Standards.
