The first step in proper pitch-line measurement is achieved by selecting the Contact Points best suited for a specific thread form and pitch. Allen Contact Points assure repeatable, accurate thread measurements through a consistency in dimensions and concentricity. Whenever possible our contacts are made from Tungsten Carbide to meet the most exacting standards of long life and consistent pitch-line measurement. A variety of sizes are supplied in Plain Shank for Allen Lead Gauges and Threaded Shank for all other applications.
Plain Shank Ball Points for Lead Gauges models 5690-C, 5690-G and 5690-O.

Cone Point Contacts
Precise measurement of V-threads will not permit the cone to come into contact with the thread flanks. This is achieved by precise manufacturing of the contact cone angle, end radius and length, using high grade tool steel. Cone Point wear and damage can be verified on the appropriate Allen Height Standard.
Root radius measurement of API Round Thread Casing is achieved through a unique double cone design. The outer cone centers the inner contact cone for rapid and more accurate reading. For longer life, Tungsten Carbide is used in the CP 32050 inner contact cone.
