Lead Gauges- Internal and External – High Accuracy

Allen Lead Gauges are designed to check lead error on internal and external threads quickly and accurately. The gauges are used with contact points which can be set at 1/2″, 1″, 2″, 3″, or 4″ intervals allowing per-inch or cumulative errors to be measured. All gauges feature reverse tension of the moveable contact point that simplifies handling on buttress thread types, allowing measurements to be taken against the 3° flank in the same manner and ease as with any other thread. The shorter 5690-C identical to the 5690-G but has a span of up to 2″. Used with an Allen Lead Gauge Setting Standard, a lead error of 0.010 fast to 0.010 slow can be measured to the nearest 0.0005″ and estimated to the nearest 0.002″. Gauges are furnished with 0.072 diameter tungsten carbide contact points, unless otherwise specified.

Contact points from 0.18 diameter to .500 diameter can be easily changed to equip gauges for a variety of thread forms. Refer to Lead Gauge Setting Standards for best contact point sizes and matches setting standards.

External Lead Gauges: For all external threads. These gauges can also be used on internal threads 4″ nominal and larger.

5690-G

Gauge Type: External Lead Gauge, 4″
Thread Type: All API Thread types
Dial Type: 10~0~10, Balanced
Accuracy: 0.0002″ over entire range
Dial Travel: 0.020″

Description: The 5690-G is used to check lead error on any External API Thread Form. 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.
