Description: The 5690-O is used to check lead error on any External or Internal API Thread Form and therefore can be considered a universal Lead Gauge. Our latest series of Lead Gauges feature reverse tension on the moveable contact, which engages the load flank to simplify measurements on Buttress Type Threads. High accuracy coupled with the ability to make quick and precise readings have made this a user favorite for decades. The body of the 5690-G is chromed and contoured to insure durability, which will allow it to be a reliable tool for many, many years. Craftsmanship in manufacturing and hand fitting in assembly allows the gauge to read product errors of up to 0.010″ with an accuracy of 0.0002″. Measurement is determined by first “zeroing” the gauge on the second component of the measuring system, a precision ground setting standard. These are available in various pitches and accommodated for specific tapers. The third component, naturally, are the interchangeable contact points. These are made of Tungsten Carbide and available in the various diameters needed for pitch line contact. Their spacing can be varied at1/2″ intervals for a maximum cumulative lead measurement of 4″. The measurement taken then indicates the deviation from the API Nominal. The Allen Lead Gauge, 5690 Series, is without a doubt the top of line when it comes to reliability, durability, and most of all precision.

All lead gauges are furnished with 2 Allen Ball Points, a certificate of compliance to API specifications and a fitted box.
